120 th Coal Fired CFB Boiler in Petrochemical Corporation

Nongfu Spring has been committed to the production of natural and healthy drinking water, only after a simple filtration, without changing the water quality, maintain natural water features indicators, unswervingly follow the environmental, health, natural path of development. Fast 120 th coal fired cfb boiler in petrochemical corporation since its inception, focused on research and development of clean boiler design, adhere to the concept of environmental protection has become condensing gas boiler industry leader. The same faith, the same dedication to promote fast boiler and Nongfu Spring work together to create new environmental future.

Fossil fuel prices rise substantially and bring serious environmental pollution, the government had to take the coal ban policy, in this case, the biomass 120 th coal fired cfb boiler in petrochemical corporation steam supply favored by the market, this article mainly introduces how to operate biomass steam boiler for enterprises which purchased a biomass steam boiler.

Treatment of natural gas leakage in horizontal gas 120 th coal fired cfb boiler in petrochemical corporation room

According to relevant data, with the speeding up of changing coal to gas, the project that change industrial coal-fired boilers to industrial gas boiler no matter in quality or quantity are growing faster. In addition to the support of national policy, the development of industrial gas boiler also benefited from the convenience of natural gas.

According to this feature, the blower must be segmented to meet the needs of the combustion. Although the current domestic production of 120 th coal fired cfb boiler in petrochemical corporations 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.
