Travelling Grate or chain grate Stoker Boiler In Travelling Grate boiler coal is fed at one end of a moving steel chain grate. As grate moves along the length of the boiler furnace, the coal burns before dropping off at the end as ash. Some degree of skill is required, particularly when setting up the grate,

Author: Technical Concept [PDF]Traveling or Chain Grate Stokers Traveling or chain grate stokers feed coal out onto a rotating metal belt that supports the fire. Coal is fed from a hopper. Grate speed is automatically controlled to maintain desired steam pressure. Burning progresses as the belt moves from front to back of furnace.

The grate assembly (the most characteristic element in grate-fired boilers), the key combustion mechanism in the fuel bed on the grate, and the advanced secondary air supply (a real breakthrough in this technology) are highlighted for grate-firing systems.

May 28, 2017· 1.Reduction in boiler size :-in FBC boiler bed coil are installed so the more temperature gain from the fuel combustion and other side mechanical chain grate boiler no bed coils are there so high heat transfer rate over a small heat transfer are immersed in the bed result in overall size reduction of the boiler. 2.Ability to burn fines :-

[PDF]A stoker burner combusts the fuel (usually wood chips, grain, briquettes or pellets) in the burner, where the fuel is fed in automatically, and not in the boiler itself. The fuel is fed to the burner using

1. Stoker Firing . A stocker is an electric-powered fuel feeding mechanism and great. The stokers are classified into: Overfeed stokers; Underfeed stokers. Advantages of Stoke Firing . A cheaper grade fuel can be used. Higher efficiency is achieved. Less smoke production. Greater flexibility in operation. Less building space is required.

it has been shown possible to build a chain-grate stoker-fired shell boiler to burn the normal run of industrial small coals automatically and at high efficiency over a range of loads of at least 8:1 17. The boiler efficiency–load curve that can be obtained is shown in Figure 8.
