Coupled heat transfer model for the combustion and steam

This paper presents a coupled heat transfer model for coal-fired boilers that integrates boiler's fire side computational fluid dynamics (CFD) solution with the boiler's steam cycle, and thus, can pre-dict the boiler steam temperatures subject to different boiler design and operation conditions. In

How to Run a Coal Fired Boiler at the Best Efficiency

Jul 05, 2009 · Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.

Conversion of Existing Coal-Fired Boilers to Natural Gas

improves boiler cleanliness and tends to increase heat absorption. However, combustion -zone radiation rates to the furnace walls tend to be lower. Achieving design steam temperatures and full boiler output can be difficult for a boiler originally designed to burn coal. Higher tube -metal temperatures may be experienced when firing natural gas.
