Natural gas and alcohol based fuels are more advantageous

I don't think there's much advantage to the alcohol base as long as there is a gas pipeline interface. It is mainly reflected in the following aspects: the gas appliances corresponding to natural gas are more mature and safer than alcohol-based gas appliances; Pipeline natural gas will basically not be out of stock, and it can be taken at any time, without manpower and time; Pipeline natural gas is easy to meter, with little fluctuation in quality, while alcohol-based metering and quality are prone to risks; Another point is that some alcohols themselves are made of natural gas, and in the current situation of marketization, informatization, and transportation convenience, as fuel, their comparison will gradually approach.

as an emerging fuel. Alcohol-based fuel has its unique advantage is environmental protection and energy saving, the best affordable, at present, people are very optimistic about the market of alcohol oil, more and more people are beginning to use such an emerging fuel, Hebei Norka has been operating alcohol-based fuel since 06 years, after several years of development and growth in the peer emerged, the strength of the entity company.

Natural gas users need to open an account and maintain costs, which are not generally high, and they also have to buy their own stoves and equipment. Alcohol-based fuels do not incur these costs. A larger shop according to the installation of natural gas, these costs will be more than 100,000, with alcohol-based fuel can not be used at a point, but also to help you repair and install, if the local alcohol-based fuel market is cheaper, then the natural gas does not have a little advantage.

1. The calorific value is low, the combustion energy consumption is relatively high, and only by changing the ratio can it be promoted.

2. It is liquid, and it is difficult to completely gasify and burn.

3. The flame temperature is low, the fire power is small, and the heating speed is slow.

4. In the combustion process, when the temperature reaches about 250 degrees, it begins to become gas, but when the temperature reaches about 250 degrees, it begins to form carbon, blocking the gas pipe and the stove, resulting in its inability to be used normally for a long time in the gasification state.

5. When the combustion is insufficient, the exhaust gas emitted after combustion seriously exceeds the standard.

6. The technical difficulty is high, and more advanced technical research and practice are required to synthesize fuels comparable to gasoline and diesel.

Alcohol fuel is a new alternative energy source, people's understanding, practical use of it has a development process, it has many characteristics compared with ordinary gasoline and diesel, and its advantages are very obvious. Save oil in the finished gasoline, diesel mixed with 15% fuel alcohol [can also be added with a higher proportion], through the co-solvent compounding, the thermal efficiency and refined oil is basically equal, can replace the finished gasoline, diesel use to save valuable petroleum resources, save a lot of foreign exchange. In the long run, the development of the alcohol energy industry can drive the development of many industries, especially when the oil resources are exhausted, replacing petroleum fuels as the leading energy source is of great strategic significance to maintaining national energy security.

The steam pressure of safe and convenient alcohol is smaller than that of gasoline, the specific gravity is higher, the steam is less volatile than gasoline, and the risk of fire is smaller than that of gasoline; Alcohol has excellent conductivity, can reduce the risk of static electricity, less possibility of accidental fire, and its production, storage, transportation and use are safer than petroleum fuels. Alcohol vapor and diesel can be mixed with refined oil, which can be switched at any time, flexible and convenient to use. The oil supply system can use the equipment and facilities of the gas station, and there is no need to build a special oil supply system.

The power is good, the alcohol contains oxygen, which can promote full combustion, and the latent heat of evaporation is large, which can improve the thermal efficiency of the engine. Adding 15% alcohol to the refined oil can significantly increase its octane number, increase the 90 gasoline to 95 clean gasoline, upgrade the 0 diesel to 10 diesel, and the calorific value of the cartridge of M15 mixed fuel is, the net calorific value is 38MJ KG, which can fully meet the power requirements of the engine, and the experiment proves that the power of alcohol fuel is better than that of refined oil. Reducing emissions alcohol fuel is internationally recognized as a clean fuel, alcohol is an oxygenated compound, its combustion emissions are significantly lower than the harmful substances generated by oil combustion, the experimental monitoring results show that the Santana car uses M15 methanol gasoline, CO [carbon monoxide] and HC [hydrocarbon] emissions are lower than the use of 93 gasoline and respectively; M15 methanol diesel is used on Yuchai YC6105, CO is reduced, NO is reduced, and the exhaust smoke is reduced.

Disadvantages: The latent heat of vaporization of alcohol is high, which is easy to cause poor low-temperature starting performance of alcohol fuel, and corresponding measures need to be taken in winter; Alcohol is mixed with gasoline to form azeotropic substance, and the vapor pressure of methanol gasoline is significantly increased near the ratio of alcohol 15%, and when the ambient temperature is high, alcohol gasoline is easy to form gas resistance in the oil circuit, resulting in poor fuel supply to automobiles; The incomplete combustion of alcohol is easy to form unconventional pollution emissions, among which the emission of aldehydes is higher than that of conventional gasoline vehicles, which is easy to cause poisoning of automobile three-way catalytic converters; Since the calorific value of alcohol is less than half of that of gasoline, the dynamic performance of automobiles using medium and large proportions of alcohol gasoline will be affected. Alcohol is corrosive and has a swelling effect on rubber, so anti-corrosion and anti-swelling additives are often added to alcohol gasoline; Alcohol is an excellent solvent, which will damage the oil film of the cylinder wall after entering the cylinder, and it is easy to cause abnormal wear of the cylinder wall - piston ring friction pair; The incomplete combustion products of alcohol contain acidic substances, which can easily cause the engine lubricating oil to acidify in advance.

Gas, natural gas, if you insist on saying that there are shortcomings, then I think the amount of use is large, and it may be a disadvantage to be troublesome, but compared to his advantages, it is acceptable, and the gas also needs to be changed.

Natural gas is still a relatively economical energy source, but there is a danger of leakage, and other than the first time, alcohol-based fuels are not competitive with him.

Alcohol-based fuels are resource-saving and more environmentally friendly

Methanol is a hazardous chemical that can easily cause accidents after inhalation. Refined methanol is colorless and odorless, and it has affected health when people feel uncomfortable when they inhale.

Liquefied gas is used as fuel, and if the purity is high, it should burn with a blue flame and no pungent atmosphere. At present, the liquefied gas on the market is mixed with dimethyl ether, which makes the combustion yellow flame, and has a pungent smell, and sometimes people are smoked so that they can't open their eyes. However, it is not very harmful to the human body.

At present, the installation of natural gas pipelines has become widespread in many places. It is recommended to use natural gas, although a one-time investment of 2000-3000 yuan, but at least good combustion and little harm to the human body. If the landlord is a small restaurant operating for a short time, or the local area does not support the installation of natural gas pipelines, use liquefied gas.

But don't use methanol, this thing will have too much impact on the people around you after leaking, it can be poisoning at least, and it will cause a risk of death or **.

1. Safety. Once liquefied gas leaks, it can easily happen**. Alcohol-based fuels are called "fuels that will not be **", alcohol-based fuels can only be ignited with open flames, cigarette butts are not, and once leaked, they can be diluted and doused directly with water.

2. Low cost. Generally at least 50% lower than liquefied gas**, but consumption is a little higher than liquefied gas, saving at least 30% of fuel costs overall.

3. It is more convenient to use than liquefied gas, and there is no need to change the liquefied gas tank frequently.

Alcohol-based boilers are mainly fueled by alcohol-based liquids, and the cost is much cheaper than natural days.

Relative gas boiler advantage version: methanol boiler does not need expensive gas opening costs, the opening fee of 1 ton gas boiler is about 100,000 yuan, if you use methanol boiler opening fee can be saved. In addition, the cost of methanol boiler is cheaper, the cost of methanol boiler to produce 1 ton of steam is 101kg of methanol, calculated at 2000 yuan, the cost of methanol boiler is 202 yuan, the cost of 1 ton of gas steam boiler is 80m natural gas, and the cost of natural gas boiler is 304 yuan in yuan m.

If it is used for 10 hours a day, the methanol boiler can save about 1,000 yuan a day.

The advantages of methanol boilers can also be manifested as:

Good environmental benefits Methanol is a new energy, which will not cause pollution to the environment and can be used in industrial parks and urban areas; Low operating noise, the fan is integrated on the burner, the servo motor is automatically controlled and operated, the noise is less than 60 decibels, and it will not cause noise pollution to the surrounding environment;

Extensive energy Methanol is a biofuel, which is widely sold in major cities across the country, and the use of energy is easy to obtain;

No opening costs Natural gas pipeline openings require a large opening cost, which can be eliminated by methanol boilers;

Low fuel cost Compared with natural gas and oil, methanol has a lower cost and can effectively save operating costs.

Alcohol-based fuel is a fuel that is mainly configured with alcohols (such as methanol, ethanol, butanol, etc.) substances. It exists in liquid or solid form. It is also a kind of biomass energy, like nuclear energy, solar energy, wind energy, and hydro energy, and is an environmentally friendly and clean energy that is currently vigorously promoted by various countries; In the face of the depletion of fossil energy, alcohol-based fuels are the most potential new alternative energy sources, which are favored by enterprises and organizations in various countries.

Alcohol-based fuels are readily available and can be obtained in the future like alcoholic liquor. There will be two kinds of liquor in the future, one for drinking and one for burning"Wine"It's alcohol-based fuels.

Alcohol-based fuels can be used in catering and industrial boilers. Alcohol-based fuels have obvious economic comparability - compared with liquefied gas, diesel, and kerosene, high thermal efficiency is its best feature, and the advantages of alcohol-based fuels have attracted the attention of the industry since 08. But it is technically difficult, to synthesize gasoline, diesel fuel needs more advanced technical research and practice, as of the end of 2012, the domestic petrochemical oil and alcohol-based environmental protection oil full performance testing and research and development.

Alcohol-based fuel is a green energy source - compared with coal, coal tar, heavy oil, diesel and gasoline, alcohol-based fuel burns most completely and thoroughly, has the highest heat conversion efficiency, and is mainly water and carbon dioxide, which is the cleanest, most environmentally friendly and most promising fuel in the future. Alcohol-based fuels have been used in fighter fleets in developed countries to replace jet fuel for aviation. Compared with other fuels, the storage and transportation of alcohol-based fuels are relatively simple, and it has been said before that the transportation precautions of alcohol-based fuels!

It is recommended to use plastic drums when storing alcohol-based fuels, because iron drums are easy to react with methanol and corrode iron drums! When the world is discussing energy conservation and emission reduction, all countries are considering the use of new energy to meet the requirements of energy conservation, such as wind energy, solar energy, alcohol oil, etc., oil is still the oldest and most common energy source in the world, but on the one hand, due to the non-renewable nature of oil, on the other hand, due to the consequences of oil to the atmospheric environment, all countries have to consider new energy attempts! Therefore, bioalcohol oil energy is still very promising in the future!

Advantages: The combustion value of biofuel is lower than that of liquefied gas and diesel, but it has the advantage of being used as a substitute fuel for petroleum liquefied gas and fuel diesel, it is low-priced, safe and convenient, with no residue residue, no black pot bottom, with clean and hygienic, safe, cheap, easy to buy raw materials, easy to use, etc., and is a biomass clean energy encouraged by the state to develop. The cost is only about one-third of that of petroleum liquefied gas or diesel wholesale**, with huge profit margins and extremely high investment value.

This type of fuel oil is a replacement product of alcohol-based liquid fuel, which solves the problems of low calorific value of alcohol-based liquid fuel, furnace fire, low thermal efficiency, large consumption, environmental protection and uneconomical. It not only fully complies with the national standard for alcohol-based liquid fuels, but also has been greatly improved and improved in terms of calorific value, viscosity, flame temperature, etc. At present, most of the catering industries such as restaurants, guesthouses, and canteens of colleges and universities in large and medium-sized cities in China use diesel and liquefied gas as Chinese food stoves in energy, and some still burn coal.

Bioethanol oil is an environmentally friendly biofuel newly developed on the basis of alcohol-based fuel, which can be stored, transported and used at room temperature and pressure, without high-pressure cylinder storage, and can be stored in ordinary metal or plastic containers.

1. Different compositions: artificial gas uses hydrogen, methane, and carbon monoxide as the main components; Natural gas has methane as the main component.
