coal. Many cyclone boilers currently operate the cyclone barrels substoichiometrically to reduce NOX emissions. The balance of air required to complete combustion is provided through overfire air ports. The extent of staging is limited by the minimum heat release in the barrel that is required to keep the slag molten and free flowing.

What the Power Industry Should Know about Cyclone Boilers

A cyclone-fired boiler is designed to burn crushed coal to generate electricity. It is just one of many boiler types designed to burn coal. Coal-fired boilers generate over 55 percent of U.S. electric power. The boilers with the highest capacity (by megawatt) are designed to burn either pulverized coal (PC) or crushed coal. The PC-fired

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Applicability of NO Combustion Modifications to Cyclone

Cyclone-fired, primary steam-generating capacity in the U.S. totals approximately 26,000 kg/s, about 9% of the total U.S. steam-generating capacity. Cyclone boilers have traditionally been labeled as high NO emit- ters. Coal-fired cyclone boilers contribute nearly 20% ofxthe NO emissions from all coal-fired utility boilers.

Fireside Deposits In Coal-Fired Utility Boilers

by B&W for cyclone-fired boilers, but industrial experience has shown that a maximum T -250 of 24500F is more realistic in avoiding slag tap pluggages. The author has shown23 that coals with T-250 greater than 24500F can be used if they possess high heat content. These coals generally have low moisture and ash content and, therefore, more heat is

Combustion occurs at very high temperatures: 3200°F to 3550°F (1760–1950°C). The fuel for cyclone boilers is typically a bituminous coal prone to slagging; it may be blended with other coals and/or petroleum coke, biomass, or other fuel materials. Some cyclone boilers are fired with subbituminous coals, while others are fired with lignites.
