The unit was originally equipped with a traveling grate stoker designed to fire the boiler at 170,000 lb/hr steam at 1250 psig operating at 955°F. Stoker reliability had become a problem causing unplanned outages for repair of seals, chains, grate bars and grate clips.Learn More
refractory cells to stationary grate spreader stokers to stokers primarily designed to burn coal. In 1938, in the United States, the traveling grate spreader stoker was developed to burn coal and quickly became the predominant firing equipment for industrial coal fired boilers. In 1944, the first traveling grate spreader wasLearn More
Main Advantages of Converting Stokers into FBC • Stokers with traveling grates need excess air at levels of about n = 2.0 whereas AFBC can operate at levels of n = 1.3 • This raises boiler efficiency due to lower flue gas loss because of reduced flue gas flow rates • With in-bed heating surfaces power is raised by nearlyLearn More

efficient combustion. Stoker-fired boilers were first introduced in the 1920's for coal, and in the late 1940's the Detroit Stoker Company installed the first traveling grate spreader stoker boiler for wood. In the basic stoker design, the bottom of the furnace is a moving grate …Learn More
boilers. Underfeed and traveling grate stokers have large furnace areas and consequently lower volumetric- and surface area-based heat release rates. Lower heat release rates reduce peak combustion temperatures and, hence, contribute to lower NOx emissions. In addition, the partially staged combustion that naturally occurs in all stokers due to Learn More
