Crispin, L G

Babcock and Wilcox, under contract with Electric Power Research Institute, conducted preliminary design studies and a series of cycling field tests on an oil-fired, subcritical once-through boiler designed for base load operation. The field tests indicated what design changes should be made to the plant prior to being used for cyclic operation. Major concerns with the existing plant are thermal shock damage to the boiler, water clean-up, high temperatures in furnace tubes, steam temperatures in furnace tubes, steam temperature control during start-up, and difficulties coupling the cross compound turbine generator fields. Preliminary design studies indicate that for reliable on/off cycling operating, the boiler should be retrofitted with spiral furnace circuitry and an updated bypass system, and the turbine and large motors should be checked for their ability to start and stop a large number of times.
