boiler rice husk fired

Third, the installation of blowdown or heat exchanger.

To the steam boiler blowdown installed on the heat exchanger or boiler blowdown recycle, and subjected to rigorous controls to ensure emissions below 5%, and if the best conditions to control below 2%. In addition, heat may also be recovered by utilizing a trap device expansion, so that the work holder can also trap properly. Trap in the steam condensate, water quality is often good, it comes from the quality of the boiler feed water, the recovery process can also save the cost of water.

When the boiler rice husk fired operation, the reason of maintaining the water level in the normal range: the boiler drum water level is too high, will affect the effect of water separation, the wet saturated steam fraction increases, increased salinity, and likely to cause wall superheater Steam Turbine sCALING stream, superheater flow area decreases, the resistance increases, to improve the heat resistance, the wall-temperature, and even burst pipes; the other also result in increased moisture vapor turbine efficiency is lowered, increasing the axial thrust and the like. Serious water superheated steam temperature over a sharp decline in the steam piping and steam turbine to generate water impact. Cause devastating accidents.

How to prevent the boiler rice husk fired furnace coke? In order to prevent the boiler coking, on the run may take the following measures: (1) a reasonable adjustment of combustion. Flame distribution in the furnace, the flame is not deflected center; (2) to ensure the proper amount of excess air, to prevent combustion hypoxia; (3) to avoid operating the boiler load exceeds the force; (4) ash periodically. Ground inspection found that fouling and coking village promptly removed. In terms of maintenance should be done: (1) improve the quality of maintenance, to ensure accurate installation burner; the boiler (2) maintenance tightness better, to prevent air leakage.

Recently, Guizhou Province to combat air pollution, protecting and improving the quality of atmospheric environment, the protection of public health, promote the construction of ecological civilization, and promote comprehensive, coordinated and sustainable economic and social development, in accordance with the provisions of "People's Republic of China Air Pollution Prevention Law" and relevant laws and regulations of atmospheric pollution prevention and control regulations to be amended.
