Water Tube Boiler - Types, Working, Construction & Applications

2019/8/28 · Water Tube Boiler is a high-pressure boiler that operates at a pressure of about 165 bar. Basically, in this boiler, water will be flown inside the tubes surrounded by flue gases. More steam is generated by using this boiler so, the overall efficiency of the boiler is high. The water Tube boiler is shown in the figure below.

Description of Boiler Tube Grades & Recommended Uses per the ASME Boiler & Pressure Code Section 1 SA178 & SA213 grades - Chicago Tube & Iron

BOILER TUBE GRADES CARBON STEEL SA178 Carbon steels show mild corrosion resistance and fair strength up to 1000F. However, their usage above 800F must take into account the susceptibility to graphitization. Graphitization has not been a significant problem in thicknesses encountered in boiler tubing. Use of heavy section pipe above 800F, however, is not recommended. […]

Engineering Timelines - Richard Trevithick - High pressure steam

The first of Trevithick's high pressure engines, a steam whim working expansively at 172kN per sq m (25psi), was begun at Cook's Kitchen mine in 1800. It had a 480mm diameter cylinder with a 1.52m stroke and was still working in 1870. To cope with the higher pressure, he designed a wrought iron cylindrical boiler with internal "tube and fireplace".
