The introduction of industrial kilns, the difference between industrial furnaces and gas furnaces

A kiln is a refractory material used to calcine materials or fired products.

The differences between them are as follows:

1. Different fuels: Industrial furnaces usually use various different types of fuels, such as coal, oil, natural gas, liquefied petroleum gas, etc. These fuels are burned to produce high temperatures and heat energy, which are used to heat materials in industrial furnaces.

Gas furnaces, on the other hand, use gas as the main fuel. Coal gas can be natural gas, liquefied petroleum gas, etc. It is burned to produce high-temperature rent and heat energy, which is used to heat the materials in the furnace.

2. The working principle is different: industrial furnaces usually use the high temperature and heat energy of burning fuels to heat the materials. They are usually heated either directly or indirectly.

The gas furnace uses the high temperature and heat energy generated by burning coal gas to heat the material. They typically use a gas burner to spray gas into the furnace chamber.

Legal analysis: This standard stipulates the maximum allowable emission concentration and emission limits of industrial furnace smoke, production dust, harmful pollutants and smoke blackness according to the number of years. This standard is applicable to the management of industrial furnaces and kilns that use solid, liquid, gaseous fuels and electric heating other than coke ovens, incinerators and cement plants, as well as the environmental impact assessment, design, completion acceptance and emission management of industrial furnace construction projects.

Legal basis: Standardization Law of the People's Republic of China

Article 14 Mandatory standards must be implemented; Products that do not meet the mandatory standards are prohibited from being produced, sold and imported; Recommended standards, which the state encourages enterprises to adopt voluntarily;

Article 15 Enterprises with national standards or industry standards for products, can apply to the competent standardization administrative department or the department authorized by the standardization administrative department to apply for product quality certification.

1) If the certification is qualified, the certification department shall grant the certification certificate, and the certification mark shall be allowed to be used on the product or the packaging of Qingshan Qing.

2) The products that have obtained the certification certificate do not meet the national standards or industry standards, and the products are not certified or unqualified, and the certification mark shall not be used for sale.

A boiler is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam. The original meaning of pot refers to a container of water heated on a fire, and a furnace refers to a place where fuel is burned, and a boiler includes two parts: a pot and a furnace. The hot water or steam produced in the boiler can directly provide the heat energy needed for industrial production and people's lives, and can also be converted into mechanical energy through steam power devices, or converted into electrical energy through generators.

The boiler that provides hot water is called a hot water boiler, which is mainly used in life, and there are also a small number of applications in industrial production. The boiler that produces steam is called a steam boiler, often referred to as a boiler, and is mostly used in thermal power stations, ships, locomotives and industrial and mining enterprises.

The "pot" in the boiler refers to the part of the boiler equipment that holds water and gas and bears pressure, and its function is to absorb the heat released by the "furnace" and heat the water to a certain temperature and pressure (hot water boiler) or evaporate it into steam (steam boiler). "Furnace" refers to the part of the boiler equipment where the fuel reacts with the air to produce high-temperature flame and flue gas, and its function is to maximize the release of the heat energy of the fuel for the "pot" to absorb.

Industrial kilns and industrial furnaces are collectively referred to as industrial kilns. Industrial kilns mainly refer to those devices that use combustion reactions to heat materials. "Kilns" are mostly used in silicate industrial systems, such as furnaces for the production of ceramics, glass, cement and other products.

"Furnace" is mostly used in metallurgical and mechanical systems, mainly used to smelt and prepare steel and various non-ferrous metal materials, and can be divided into roasting furnaces, blast furnaces, cupola furnaces, converters, open hearths, soaking furnaces and crucible furnaces according to their uses.

The biggest difference between a boiler and an industrial kiln is that a boiler has a "pot" and a "furnace", while an industrial kiln only has a "furnace".

To put it simply, industrial furnaces are generally used to heat and dry objects. Boilers are generally used to burn steam or hot water.

Industrial kilns mainly refer to those devices that use combustion reactions to heat materials.

A boiler is a device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam.

1. According to the variety of calcined materials, it can be divided into: ceramic kiln, cement kiln, glass kiln, enamel kiln, lime kiln, etc.;

2. The former can be divided into continuous kiln (tunnel kiln), semi-continuous kiln and batch kiln according to the operation method;

3. According to pyrogen, it can be divided into: flame kiln and electric kiln;

4. According to the condition of the heat source facing the green body, it can be divided into open flame kiln, flame isolation kiln and semi-flame isolation kiln;

5. According to the green body carrier, it can be divided into kiln car kiln, push plate kiln, roller bottom kiln (roller kiln), conveyor belt kiln, walking beam kiln and air cushion kiln, etc.;

6. According to the number of channels, it can be divided into single-channel kiln, double-channel kiln and multi-channel kiln.
