摘要

With China's economy growing rapidly, requirement of electricity is more and more. Now, 300MW coal-fired units are main units. With diversification of coal, there are big differences between actual coal and design coal, this affect on the safety of running. In this paper, a 300MW coal-fired unit was studied. A, B and C three kinds of mixed coal were chosen. Under the rated load, characteristics of coal were studied. Experiments of adaptabilities of mixed coal A, B and C with boiler were done. And results indicated that slag of boiler was related with distribution of fire box temperature, degree of flame-brush wall and degree of flue-gas turbidness. Slag of mixed coal C was serious, while mixed coal A was not easy lagging in superheater and water wall. Therefore, mixed coal A as fuel could meet the need of safe running of boiler.
