An Economiser Boiler is an energy-efficient boiler component designed to recover waste heat from exhaust flue gases and utilize it to preheat boiler feed water before it enters the boiler system. This heat recovery process significantly improves overall boiler efficiency, reduces fuel consumption, and lowers operating costs.

Economisers play a vital role in enhancing thermal performance by minimizing heat loss through flue gas discharge. By increasing the feed water temperature, they reduce the energy required for steam generation, resulting in faster steam production and improved boiler reliability.

Widely used in industrial steam boilers, thermal power plants, and process heating systems, economisers support energy conservation initiatives while helping industries reduce emissions and improve operational efficiency.
