water, and the thermal conductivity of the cooling tube material. The "cold end" of the thermal system of the power station is formed by a condenser, a low pressure cylinder and a water supply system. 2.2 Conventional cold junction optimization method . The water in the wet cooling tower is a heat sink, and the air is a heated body. The air absorbs

Failure Analysis and Control Optimization of RB Test Due

Jul 01, 2019 · As for the 1000MW ultra-supercritical unit of Beijiang Power Generation Co., Ltd, the FDF runback test (RB) is failed for the excess reducing of feed-water flow, and the reason is analized. In order to optimize the RB control logic, the method by using slow-to-fast pressure changing rate is applied during the RB process. Besides, the slowly interlock opening control logic of the motor

Combustion Air Requirements:The Forgotten Element In

Temporary air intakes such as open boiler room windows can be closed (and often are when persons in the boiler room are feeling cold), cutting off the boiler's air supply. When the combustion air supply is closed off, the fire starts to smoke as the air supply is exhausted. Incomplete combustion occurs and carbon monoxide is generated.
