Waste heat recovery boiler are classified in two major categories:fire Tube waste heat recovery boiler and water tube waste heat recovery boiler which can also be divided into Natural circulation waste heat boiler and Forced circulation waste heat boiler.
The flow of water and steam within the boiler circuit is called circulation.Adequate circulation must be maintained to carry away the heat from the flue gas. If circulation is caused by density difference, the boiler is said to have natural circulation. If a pump causes it, it has forced or controlled circulation.
1. WHRB involves boiling of water, thus process involves very high heat
transfer rate. It is a compact unit requiring less surface area.
2. Cost of installation is usually lower than other waste heat recovery units.
3. The WHRB can withstand high exhaust temperature
4. Response rate is high and load can be adjusted by varying the steam
pressure with the help of the safety valve.
5.The temperature of the tube wall is close to the boiling liquid temperature.

Natural circulation waste heat recovery boiler can be maintained up to 30 bar.Both the down comers and riser tubes are placed inside the furnace. However, for pressure above 30bar, down comers are placed outside the furnace.
Natural circulation waste heat recovery boiler is used among others for heat recovery in iron, steel, copper, zinc, glass,ceramic and cement industry.Also it is used behind coke ovens, gas turbines,Diesel engines, sulfur burning plants and refuse incineration. The waste gases of wood, bagasse or black liquor are utilized.
