africa coal boiler suppliers

According to this feature, the blower must be segmented to meet the needs of the combustion. Although the current domestic production of africa coal boiler supplierss are taken into account this feature, using the sub-air room, and is equipped with a damper. However, according to the survey, many units in the actual operation is not performed in accordance with the combustion characteristics of air volume control, the amount of air required for combustion and an actual amount of supply air does not fit very well, so that incomplete combustion loss increases. Therefore, adjustment the combustion in the boiler, the air amount to be supplied to the combustion timely adjusted according to need, to reduce heat loss and improve the thermal efficiency. 3. The use of secondary air. Strengthening of the combustion secondary air stream is very effective, it has the following effects: (1) strengthening the furnace turbulence and mixing of the gas stream in the furnace oxygen and fuel gas are uniformly mixed, so that the chemical loss of incomplete combustion and furnace excess air coefficient is decreased. (2) the secondary air vortex formed in the furnace flue gas, on the one hand to extend the suspension of fine coal particles travel in the furnace increases the residence time of the suspension of fine particles in the furnace, so that there is sufficient time than combustion, incomplete combustion to reduce heat loss; on the other hand due to the separation effect of the vortex gas flow, the coal particles and ash particles thrown back to the furnace, reducing the amount of fly ash escaping the mechanical incomplete combustion to reduce heat loss. (3) the high temperature secondary air in the furnace flue gas is improved fullness, that eliminates dead reduced stagnation zone and improve the utilization of the furnace heating surface. In addition to the secondary air had a marked effect on energy conservation, but on the smoke and dust is also very effective.

Fast africa coal boiler suppliers particularly strong technical team, they listened carefully to our needs and give us tailored technology solutions, from boiler production, transport to the site installation and commissioning took only 35 days time, all aspects of the deal in place, the boiler quickly it is put into use. --customer feedback

75ton h CFB africa coal boiler suppliers

Circulating fluidized bed combustion technology mechanism research, has assumed the "research and test modeling and numerical simulation of large-scale circulating fluidized bed combustion system working process," nearly ten National Natural Science Foundation, the national "eight five" key project and "circulating fluidized bed gas-steam generation equipment research," national "Nine Five" project "75ton circulating fluidized bed package design," and the National Key Basic Research Development Program projects. In cooperation with Canadian institutions concerned a joint application to the Canadian International Development Agency CIDA Canadian project "Development Research burning coal combustion CFB China", made a series of achievements in scientific research, especially in the circulating fluidized bed combustion , heat transfer, desulfurization and other aspects of a deeper study, in cooperation with the United Technologies Corporation a "vortex fluidized bed combustion technology research", in cooperation with the US F & W company "a new gas-solid separation technology research." Cooperation with South Korea development of large-scale circulating fluidized bed boiler. In extensive research on the basis of the mechanism for circulating fluidized bed combustion technology with sufficient awareness, especially in the hydrodynamic characteristics of circulating fluidized bed, a circulating fluidized bed coal and special fuels (anthracite, coal, coal, raw biomass fuels, coal, petroleum coke, etc.) of the combustion characteristics of a circulating fluidized bed furnace heat transfer characteristics and tail heating surface, the control process pollutants (SO2, NOx and heavy metals) circulating fluidized bed combustion, circulating fluidized Key components such as splitters bed, feed back mechanism and external fluidized bed heat exchanger. The main fluidized bed combustion test rig owned are: cross-section of 200 × 200 high as cold circulating fluidized bed test stand 4000, cross-section of 200 × 200 high of 4000 circulating fluidized bed thermal test bench, sectional as high as 500 × 500 6000 circulating fluidized bed thermal test bench, cross-section of 350 × 350 high as 10,000 hot circulating fluidized bed test bed 1MW fluidized bed combustion test stand and vortex. In addition to research in the laboratory scale test rig performed, still 75t / h circulating fluidized bed boiler and 220t / h circulating fluidized bed boiler exhaustive testing, to obtain large flow boiler, combustion, heat transfer, pollutant Characteristics emissions.

biomass/coal fired steam africa coal boiler suppliers for tofu machine

Our biomass/coal chain grate boiler in structural design, relative to the larger space of the traditional boiler hearth, while the layout of a secondary air, a reasonable composition of the aerodynamic field, to ensure that flue gas in the furnace residence time to avoid the tiny carbon particles are taken out of the furnace, So that a large number of volatile components precipitated instantly burning biomass fuel combustion.
