Apr 21, 2015 Coal Burning Equipment Traveling-grate or Chain-grate Stoker • Popular type of mechanical firing device in which coal is fed from a hopper onto a grate moving through the combustion chamber. • The grate consists of a number of cast iron bars interlocked to form a grate. The traveling-grate stoker has more closely interlocking bars.

What are the Different Types of Combustion Equipment?

Feb 10, 2021 Combustion equipment consists of machinery designed to burn a fuel source in combination with the oxygen in air to produce heat and energy. The different types of combustion equipment include furnaces, boilers, turbines, and engines. The design can be further identified by the fuel source such as oil, natural gas, coal, or wood.

Coal pollution mitigation

Combustion By-products By-products of coal combustion are compounds which are released into the atmosphere as a result of burning coal. Coal includes contaminants such as sulfur compounds and non-combustible minerals. When coal is burned, the minerals become ash (i.e. particulate matter or PM) and the sulfur forms sulfur dioxide (SO 2).

Coal-seam fire

A coal-seam fire is a burning of an outcrop or underground coal seam. Most coal-seam fires exhibit smoldering combustion, particularly underground coal-seam fires, because of limited atmospheric oxygen availability. Coal-seam fire instances on Earth date back several million years.

Pulverised Coal an overview ScienceDirect Topics

Pulverized coal firing ensures complete combustion of coal, thus ensuring higher efficiency of steam generators. It is predominantly adopted in large coal-fired utility boilers. The finer the grinding of coal, the more efficient its combustion.

Coal combustion and electricity generation efficiency

Why energy efficiency? Much effort is currently being focused on reducing greenhouse gas emissions from coal-fired power generation. However, it is just as important to reduce the amount of carbon dioxide (CO 2) that ends up in the waste flue gas that comes out of the flue stack of a power station.This is done by improving the efficiency of the coal combustion process.

Spontaneous Coal Combustion Part 2: Chemical Inhibitors

With lower demands for coal in the US over the years, many coal-fired power plants end up storing larger volumes of coal, increasing the probability of a spontaneous combustion event. Not only are fires a concern, but so is dust, wet coal, deterioration in coal quality (decreased BTU content), and erosion.
