INCREASING THE ENERGY EFFICIENCY OF BOILER AND HEATER

Circulating Fluidized Bed (CFB) Boilers. A circulating fluidized bed (CFB) boiler features higher gas velocity (superficial flow velocity) in the furnace (combustor) compared with a bubbling fluidized bed (BFB) boiler. The boiler activates a mixture of particles and gas to improve combustion reaction. Moreover, the fluid sand and fuel issuing out of the furnace are collected in a cyclone and recirculated into the furnace again, thereby improving combustion …

Alfa Laval - Saving fuel

The fuel consumption of a fired heater/furnace can be reduced by using waste heat from the plant for preheating the heater feed. Again, this reduces fuel bills, cooling system load, and greenhouse gas emissions. 10 MW of recovered heat can lead to annual fuel savings of 3,000,000 EUR, assuming: The need for 10 bar (a) process steam is reduced.
