Thermal power plant flue gas waste heat storage peak load regulation

What is a heat pipe flue gas waste heat utilization system?

A heat pipe flue gas waste heat utilization system is installed in front of the inlet of the electrostatic precipitator of a boiler to heat the condensate of the steam turbine. In order to understand the performance characteristics of the system, the performance evaluation of flue gas waste heat utilization and transformation is carried out.

Can exhaust flue gas be used to improve thermal power plant efficiency?

The exhaust flue gas will be emitted to the atmosphere. But we can use the heat energy of the waste gas to improve the efficiency of the thermal power plant. But if the temperature of the exhaust gas drops low will lead to the formation of the acids which will reduce the efficiency of the boiler[2,3].

How a thermal power plant works?

That the heat of the flue gas is used in the condensate system. That one of the low pressure heater (LPH) is replaced by the flue gas heater. So the efficiency of the thermal power plant will be improved and the energy used by the power plant will be reduced. The thermal power stations are used to generate electricity for a long time.

What are the performance characteristics of flue gas waste heat exchanger?

In order to understand the performance characteristics of the system, the performance evaluation of flue gas waste heat utilization and transformation is carried out. When the load is 310 MW ∼ 325 MW, the average flue gas temperature drop of the heat pipe heat exchanger is 26.3 °C.

Why is tail flue gas a problem in coal-fired power station boilers?

There is a common problem that the waste heat of tail flue gas is directly discharged into the atmosphere without utilization in large coal-fired power station boilers. The flue gas emission of boiler will not only increase the energy loss of thermal power, but also cause damage and pollution to the environment .

Does flue gas save energy?

Therefore, the waste heat recovery and utilization of flue gas is of great practical significance for saving energy, reducing consumption and improving the economy of units for large-scale coal-fired power plant boilers .
