The working principle of the cigarette lighter.

The economizer is a heat-exchange device located in the flue gas duct at the rear of the boiler. It utilizes the waste heat from flue gases at temperatures ranging from 400 to 600°C to preheat high-pressure feedwater, bringing its temperature close to the saturation state corresponding to the drum pressure.

What is the function of an air preheater?

Waste heat recovery: Utilizing flue gas heat to preheat combustion air, reducing flue gas temperature (which can be lowered to 100–120℃) and improving boiler thermal efficiency by 5%–15%.

The working principle of a superheater

The superheater is a component in a boiler that heats saturated steam into superheated steam by absorbing heat from high-temperature flue gases, thereby raising the steam temperature to improve power generation efficiency and protect turbine equipment.

The difference between superheaters and reheaters

The superheater boosts the initial energy of the steam, while the reheater optimizes the efficiency of the intermediate- and low-pressure cylinders. Together, these two components can increase the system’s thermal efficiency by 4% to 6%.
