Novel Diode Laser Cladding of High Temperature Alloys for Used in Ultrasupercritical Coal-Fired Boilers …

This project will develop novel cladding processes based on the use of a high-power direct-diode laser, the smallest and most efficient laser in the world today. The diode laser will enable the welding of very thin, smooth, low-slag-adhesion clad layers of creep resistant alloys onto steel substrates, with little or no dilution, with low distortion, and at very high deposition rates.

What are Boilers and Their Types? - Engineering Choice

In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be the combustion of coal, oil, or natural gas. In some cases, byproduct fuel such as the carbon-monoxide-rich off-gasses of a coke battery can be burned to heat a boiler, biofuels such as bagasse, where economically available, can also be used.

Oxyfuel Combustion - an overview | ScienceDirect Topics

However, because of high power consumption on the application of oxygen-rich combustion, the economy of oxy-fuel pulverized-coal boiler was not good. The focus of oxy-fuel combustion technology then changed to circulating fluid bed boiler.
