240t / h boiler successfully used fly ash re-combustion system energy-saving effect is remarkable
 
November 19 to 25, the boiler plant in the 240t / h boiler on the fly ash re-ignition system test run, and the experimental data were recorded in detail, proved by the fly ash re-use technology, the boiler The amount of coal produced by the standard coal increased by 6.8%, the content of fly ash combustible material decreased by 38.56%, reached the expected target, and achieved remarkable energy saving effect. April 2015, for the boiler operating cycle is short, serious wear and tear of the wall, the experience of the same industry power plant, according to the actual production situation, the boiler plant put forward seven technical transformation techniques. The company leaders on the above technical transformation project attaches great importance to convene several times to promote the boiler plant technological transformation measures to promote the special meeting of the boiler plant energy-saving measures fully affirmed and put forward the guidance and requirements, the meeting requires production, mobile, Anhuan Department to assist the boiler plant to complete the implementation of the above projects. After the meeting, according to the spirit of the meeting, the boiler plant set up a leading group of scientific and technological research to security as the main line, to ensure the safety of boilers and other equipment on the basis of the implementation of the transformation.
 
Fly ash rejuvenation as an important part of technological transformation technology, is to meet the "Zibo City, the use of coal clean supervision and management approach" to improve the requirements of coal calorific value proposed. In accordance with the management requirements, the boiler must burn high calorific value coal, and this coal price is high, easy to cause boiler bed temperature is not easy to load, but the advantage is reduced coal consumption, the boiler wear will be reduced. In order to better burn high calorific value coal, must be combined with fly ash re-combustion technology, the primary combustion of fly ash once again returned to the furnace secondary combustion, both to increase the amount of circulating ash in the furnace can also be fully burned ash residual carbon Increase the efficiency of the boiler.
 
The results show that the flies can meet the environmental protection requirements, reduce the discharge of pollutants, and can solve the problem of boiler wear to ensure long-term operation of the boiler, thereby reducing maintenance and maintenance costs, while saving energy saving effect, Steam volume of 100,000 tons, will save 860 tons of 5300 kcal coal, according to 50% of the annual investment rate, with the fly ash after the comprehensive economic benefits, the annual reduction of the efficiency of about 252 million yuan.
