Boiler Introduction | CleanBoiler.org

In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Since tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (as high as 3,000 psi) are required.

Water Tube Boilers - Solid Fuel Water Tube Boiler

Our offered Water Tube Boilers are a form of boiler in which steam is generated by circulating water through tubes exposed to the source of heat. This provides maximum steam pressure with a bi drum water tube design that has proven performance and reliability. Additionally, the overall water holding capacity is high and the boiler responds quickly to sudden peak load steam demands.
