A waste heat recovery boiler is a device which recovers the heat produced by another industrial process or equipment such as a genset, incinerator, furnaces, etc. Many industrial processes produce heat which is rejected into the environment as waste. This heat can be captured by the boiler and used to generate steam.
The steam which flows through the exhaust is diverted by means of a diverter to pass through the boiler and then to the exhaust.
This steam generated by the boiler can be used for a variety of functions such as to generate power, for other application such as in the case of a textile mill, for heating, etc.
Other benefits of Waste Heat recovery Boilers are that they reduce pollution and the temperature of the exhaust gas. This reduces the maintenance requirements of the exhaust systems.
