Dealer 10t Natural Gas fired boiler Industrial Thailand

Such as the use of coal fired dealer 10t fired boiler industrial thailands, coal heating value 5500Kcal / Kg (in terms of standard coal) around, (coal prices have continued their upward trend in the market price of 460 yuan per ton, and the purchase and sale channel is not smooth, to control the current energy under rotten mining waste and serious situation, the price of coal have continued upward momentum). 10t steam boiler steam coal consumption per ton of 0.2 ton, the price of 92 yuan. The hot gas is 8000kcal / Nm3, the price of natural gas per cubic 2.0 million, according to gas consumption per ton of steam gas consumption 80Nm3, the price of 160 dollars.

The calculated results indicate that the simulation values are consistent with the experimental values. Effect of dealer 10t fired boiler industrial thailand load on the temperature of furnace, flue gas emission, inlet and outlet flue gas of economizer was discussed based on the model. Boiler load on the increase results in a increase in temperature of furnace, flue gas emission, inlet and outlet flue gas of economizer. The main performance parameters of 65t/h oil shale CFB boiler system were discussed and preliminarily predicted by the model.

Four combustion modes of dealer 10t fired boiler industrial thailandBoiler as an energy conversion equipment, plays a very important role in industrial production, can be said to be the core main force of production enterprises. I know the boiler, but it is estimated that most people do not know much about the combustion mode of the boiler. Today, our Fangkuai Boiler will take you to understand the four combustion modes of the boiler. It can be divided into suspended combustion, boiling combustion, layered combustion and gasification combustion. The following is one by one. First, suspension combustion, also known as fire chamber combustion, is a combustion mode in which fuel is injected into the furnace with air in the form of fog, powder or gas. Suspension combustion ignition is rapid, combustion heat The efficiency is high. It is easy to realize automatic operation. The adaptability to load variation is strong. And the adaptability to the fuel is also strong. However, this combustion mode requires a high level of operation, and should not run intermittently. Secondly, boiling combustion is a kind of fluidized boiling combustion of fuel in fluidized bed under the action of appropriate velocity of air. Boiling combustion is suitable for all kinds of coal, especially inferior coal, such as coal gangue. Stone coal, and so on, this combustion mode on the size of coal particles also have certain requirements. The coal mass must be processed and broken into particles with an average diameter less than 10mm during combustion. Delivered by coal-feeding equipment Enter the furnace. Third, layered combustion, also known as fire bed combustion, is a way of burning fuel in a certain thickness on the grate. This combustion mode is only suitable for solid fuels. However, there are certain requirements for particle size (6~50mm). Layered combustion can basically adapt to solid fuel. As long as the mixture of air and fuel layer is good, and there is a certain combustion temperature, the ideal combustion can be achieved. If the air and fuel layer do not mix well, or the local air supply is insufficient, the combustion will be incomplete and the combustion efficiency will be low. This type of combustion is generally used in chain furnaces. IV. Gasification combustion Gasification combustion mainly refers to gasification and direct combustion of coal put into furnace, and this combustion mode is not suitable for coal with low ash content. High-temperature gasification and staged combustion is different from ordinary gasification combustion. Its utilization principle is as follows: under the condition of oxygen, the fuel surface is heated with high-temperature heat source above 800 ℃, so that the fuel can be rapidly pyrolysis and gasification combustion from outside to inside. Part of the high temperature produced by combustion is then gasified at high temperature, and part of the fuel is discharged for work, thus forming a continuous high temperature gasification combustion reaction.

To build greener homes, recently, the ecological environment of the Office of Hebei Province issued "on improving air quality guidance on the implementation of regional differentiation of access environment." "Opinions" clearly states: Shijiazhuang, Baoding and other eight cities as a red zone atmospheric transmission channel, a ban on new industrial projects and expansion of 10 large iron and steel, thermal power, cement and so on.

"Opinions" also pointed out that the province's administrative regions and the municipalities and districts male An District, Dingzhou City, Xinji City administrative area, is strictly prohibited new construction, expansion (except for cogeneration and the same amount of alternative projects) coal; a ban on new , expansion of production capacity of iron and steel, cement, plate glass, petrochemicals project (excluding off-site relocation of upgrading) and 35 tons of steam coal-fired boilers; prohibit new emissions intensity below the access conditions of other industrial projects.

Handan, Xingtai, Shijiazhuang, Baoding, Langfang, Tangshan, Dingzhou, classified as a red zone xinji atmospheric transmission channel. Within this administrative area (except city back removal capacity), to prohibit new and expanded (except equivalent replacement) steel, thermal power (except CHP), coke, cement, lime, gypsum, fertilizer, general casting of ferrous alloys, iron alloys smelting, carbon, other industrial projects using coal as a fuel; Jing Kun high-speed east, north wing black high speed, and Langfang, Baoding and Beijing bordering county area designated as coal ban areas, not in addition to the approval of central heating coal-fired project.

Future, Hebei Province, will strengthen self-examination, government oversight and something in the ex post regulation, the implementation of various construction projects of environmental protection requirements as well as changes in environmental quality, pollutant emissions such as the implementation of dynamic monitoring of the implementation of environmental access requirements for non-construction strictly punished according to the law project, supervise the rectification of the problem is serious, shut down or banned. Meanwhile, according to relevant laws and regulations, environmental protection requirements and regional environmental quality changes and other regional differentiation environmental access requirements will be adjusted in due course.
