Domestic development of gas burner, gas combustion and application?

The domestic gas burner is still in the research and exploration stage, mainly because of safety and quality issues, because gas is different from other fuel burners, once the gas leaks and the danger of pulverized coal or oil burners is completely different, but the domestic development speed is quite fast, the "Eleventh Five-Year Plan" has risen a group of small and medium-sized enterprises with technical strength, and its burner has become one of the few burner brands that can sell well abroad, and the manufacturer has a certain role in publicity. But the main reason is that the design of advanced gas and air premix, semi-premix and turbulent blending reflux combustion technology, thereby improving the combustion efficiency, increasing the combustion intensity and flame stability, and it happens that foreign (such as Riello, Italy and other countries) gas burners although the effect is the same, but due to the low cost value of China, so in foreign countries in a low price state, regardless of whether there is a problem with such a sales model, but it is also a high-tech and low-cost international market. The staged ignition combustion technology in the return zone is used to strengthen the combustion of low calorific value gas. Its optimized burner structure and random design with different brazier brick flame shapes, can make the flame shape form cylindrical, straight and flat, attached to the wall shape, to ensure the uniformity of the temperature field in the furnace, and the flame shape and flame length can be designed according to user requirements.

Reliable sound reduction measures reduce noise to meet environmental requirements.

It is undeniable that there is still a certain strength gap between domestic gas burners and foreign countries, but this also provides a good opportunity for China's gas burners to learn and develop. Now the highlight of the gas burner is energy saving, safety and technology, these three rings are closely related, interlocking, how to improve the domestic gas burner market, or the whole industry to form a virtuous circle of system, so as to drive the development of the industry.

Domestic gas burners are developing rapidly, and many of them are manufactured in the direction of low nitrogen or low energy consumption (energy saving).

General burners.

Low-nitrogen burners (burners).

Self-preheating burner (burner).

Summary. Gas Combustion and Applications?

Okay, wait a minute, my internet speed is a bit stuck.

You're here to solve the problem, aren't you?

Yes.

The target group of burners is wide, including boilers, smelting furnaces, furnaces, heat treatment and other fields, and heat-related industries, combustion systems are indispensable. The historical development of China's burner technology is relatively short compared with Europe and other industrially developed regions, with five to six years, strong vitality, the market is on the rise, and the production is growing steadily. The "Eleventh Five-Year Plan" has risen a group of small and medium-sized enterprises with technical strength, simply put, it is a one-stop design-processing-acceptance, which is a problem that other manufacturers rarely care about.

There is an obvious problem in China's industrial market is the low safety and quality standards, which is not only reflected in the burner industry, where does the safety come from? Let's start with these three points! Many burner companies abandon the acceptance, collect the balance of the hasty matter, after the accident can not be dealt with in time, because most of the domestic burner manufacturers are small enterprises, a few technicians can open a burner company, which is also the status quo of the domestic burner market.

Secondly, most domestic manufacturers rely on "copying" to make money, simply put, there is no innovation, which is why most domestic manufacturers cannot fight imported burners. Continue to take Beijing Kaimingyang as an example, they have the same development department as other burner manufacturers, but the difference is that the development department innovates products through physical experiments, that is, it puts an end to closed-door manufacturing. Even buying imported burners and their own developed products for use in the same furnace comparison, the author believes that this is rarely or will not be done by manufacturers, one increases the cost, the other increases the burden on developers, if there is no successful innovation but the gains outweigh the losses.

It is undeniable that there is still a certain strength gap between domestic burners and foreign countries, but this also provides a good opportunity for Chinese burners to learn and develop, and a series of problems such as quality, technology and enterprise development speed must have a detailed plan to ensure it. Now the highlight of the burner is energy-saving transformation, safety and technology, these three rings are closely related, interlocking, how to improve the domestic burner market, or the entire industry to form a virtuous circle of system, so as to drive the development of the entire industry.

It is said that in the early 70s, when ****** was visiting Europe, a progressive person gave him two 5-liter in-line water heaters when he was passing through Hong Kong on his way back. <>

After returning to Beijing, he instructed relevant people to develop this product, and under the attention of the people, the door of modern water heaters into ordinary people's homes was slowly opened; In 1979, China's first gas water heater was successfully developed in Nanjing Yuhuan Water Heater Factory, marking the end of the era of Chinese civilian pot boiling water bathing, and the people's bathing life has entered a new era; China's gas water heater has gone through 5 stages: straight discharge, flue, strong discharge, balance, and outdoor type, and each step is a technological breakthrough, and it is a step forward in the "safety" and "comfort" of bathing. <>

Among them, the in-line water heater completed its historical mission by June 2000 and was forcibly banned from sale and use by the state; China's gas water heater implementation standards have also experienced "86 standards, 94 standards, 2001 standards, 2007 standards" four standards, each time the standard is updated, marking a new level in the design and manufacturing of gas water heaters in China, but also improve the entry threshold of the industry.

With the deepening of China's reform and opening up, the rapid development of economic construction across the country, the rapid rise of high-rise civil buildings in cities, the state has put forward higher requirements for environmental protection, the vigorous development of oil and gas resources, and the application of oil-fired and gas-fired boilers has increased year by year. Looking at the development of oil-fired boilers in recent years, we can summarize the future development trend as follows:

1. High efficiency of the boiler.

2. Simple structure.

3. Use simple supporting auxiliary equipment.

4. Fully intelligent automatic control and equipped with multi-level protection system.

5. Equipped with burner (blower) and flue silencing system to reduce the noise of boiler operation.

6. It should be equipped with automatic dosing device and water treatment device.

7. Equipped with other monitoring and restriction devices, the boiler should be guaranteed to operate safely without supervision for at least 24 hours.

With the development and utilization of natural gas and the gradual liberalization of city gas utilities, the capital of Hong Kong, private and international multinational companies has rushed in, and the pure socks of the original state-owned gas companies that have been strengthened after the restructuring have gathered, making the competition for resources in the existing city gas market increasingly fierce.

The proposal of building a resource-saving and environment-friendly society, the opening up of the state to the city gas field, and the extension of pipeline construction have provided a rare opportunity for the development of city gas in China. With the advent of the opportunity period for the development of city gas, the three gas sources of natural gas, liquefied natural gas (LNG) and liquefied petroleum gas (LPG) in China's city gas will be complementary and complementary.
