Challenges when Converting Coal-Fired Boilers to Natural Gas

Riley Power recently participated in field testing on a wall fired boiler rated at 1,779,000 lb/hr of main steam flow. The boiler is an opposed fired design with two (2) levels of burners on both the front and rear walls. The natural gas supply system to the boiler utilized a single flow control valve for all the burners.

What the Power Industry Should Know about Cyclone …

A cyclone-fired boiler uses large crushed coal particles (typically 4 mesh size), which must be burned at a slower rate than PC 1 to complete the combustion process. This slower rate of combustion requires a unique burner design. 2 The burner's assembly is a long, round chamber (6- to 10-ft. diameter) formed by water wall tubes attached to

Coal-Fired Boiler - an overview | ScienceDirect Topics

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

Cyclone furnace - Wikipedia

A cyclone furnace is a type of coal combustor commonly used in large industrial boilers.. Background. Developed in the early 1942 by Babcock & Wilcox to take advantage of coal grades not suitable for pulverized coal combustion, cyclone furnaces feed coal in a spiral manner into a combustion chamber for maximum combustion efficiency.

Cyclone Boiler - an overview | ScienceDirect Topics

Cyclone boilers burn crushed (but not pulverized) coal in large (e.g., 10-ft dia.) cyclone barrels and send hot (e.g., 3200–3550°F or 1760–1950°C) gases into the furnace and then convective pass. Cyclone boilers are designed to maximize the production of slag from the inorganic constituents in fuel; inorganics are managed in this manner.
