Comparison Between Fire Tube and Water Tube Boiler

Jun 05, 2018· Comparison Between Fire Tube and Water Tube Boiler. 1 In Fire-tube boilers hot flue gases pass through tubes and water surrounds them. In Water-tube boilers water passes through tubes and hot flue gasses surround them. 2 These are operated at low pressures up to 20 bar. The working pressure is high enough, up to 250 bar in super critical boilers.

The National Board of Boiler and Pressure Vessel Inspectors

If solid fuel in suspension, liquid or gaseous fuel, or heat from a turbine engine exhaust is used to fire an ASME BPV Code Section I steam boiler, one source of feedwater supply is acceptable if the heat input can be shut off before the water level reaches its lowest permitted level. This scenario does work well with a low-water fuel cutoff. The inspector should not panic if the typical float-chamber type low-water fuel
