Cyclone Furnace for Brown Coal

摘要

The operating time of the brown coal cyclone boiler has so far been too short to give a definite opinion on its operation under continuous running. The initial difficulties with this new design, on which there was no previous experience, were in no way greater than with other known boiler and furnace types. The three months operation have shown that the specified figures have been confirmed and that the new design has come up to expectations in all essentials. The boiler plant operates reliably, and the cyclone furnace can be rapidly and flexibly adjusted to the steaming requirements. The boiler rating and efficiency, the slag flow and fusion rate, the crusher/drier efficiency and power consumption are satisfactory, and the real economy obtained in steam raising compares well with other furnaces firing Rhineland brown coal. As the result of the good experience obtained, a second cyclone boiler for firing brown coal has been ordered. This will be constructed as a Benson boiler with two cyclones for a steam output of 200 t/h, a pressure of 176 atmospheres and a steam temperature of 535 exp 0 C. (ERA citation 05:020037)
