how to improve gas firetube boiler Agent efficiency

BOILER TYPES FOR STEAM APPLICATIONS

Increasing the flue gas velocity will directly increase the efficiency (up to a point) because more heat will be transferred to the boiler. The downside of higher velocity is that it takes a larger fan and motor to provide this velocity. b. Adding turbulators inside the convection tubes of a Firetube boiler will improve …

Economizers, Watertube Boilers, Firetube Boilers

Chanute's custom economizers increase the overall boiler thermal efficiency, resulting in more steam with less fuel. Boiler efficiency increases by approximately 1% for every 40°F that the flue gas is cooled. It is widely recognized throughout the industry that economizers provide a good return on investment while also reducing carbon emissions.
