A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa).High-pressure locomotives can be considered to start at 350 psi (2.41 MPa), when special construction techniques become necessary, but some had boilers that

What is boiler | Types of boiler | How does a steam boiler

Heat Transfer In Steam Boiler. A steam boiler is designed to absorb the maximum amount of heat released from the process of combustion. There are three way (Radiation, convection & Conduction) that heat is transfer in the boiler and relative percentage of each heat transfer within system boiler is dependent on the type of steam boiler, fuels and the designed transfer surface.

Are there any condensing residential steam boilers out

Answer #1. "As far as I know, there is not anything available for steam that fits the bill. Condensing boilers are limited in their ability to condense as output temperatures rise. Steam, at 212(or so), is the hotest that atomospheric pressure water can get, therefore condensing within the boiler would be NEARLY impossible." Answer #2. "Guy is
