2. Boilers Bureau of Energy Efficiency 31 The coal-feed hopper runs along the entire coal-feed end of the furnace. Acoal grate is used to control the rate at which coal is fed into the furnace, and to control the thickness of the coal bed and speed of the grate. Coal must be uniform in size, as large lumps will not burn out com-
The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion. Excess air to achieve highest possible efficiency for some common fuels: 5 - 10% for natural gas. 5 - 20% for fuel oil. 15 - 60% for coal.
EPA Emissions Rules for Boilers The EPA has published two new rules for boilers in an effort to reduce emissions of air pollutants. The two rules are the Major Source Rule (also known as the Boiler MACT or BMACT) and the Area Source Rule. The information, forms, and tools necessary for compliance are included in this package.

Smokeless coal-based solid fuels in an open fire or solid fuel stove still give off that cosy glow that makes a room feel homely and welcoming. Some homes also have coal-fired boilers. However, the disadvantage of coal is the need to find room to store it and then move it piecemeal to the fire or boiler.
Features & Benefits. Burn Less Coal - A hallmark of Central Boiler furnaces for over 30 years, spray-on urethane is the ultimate airtight, waterproof insulation that locks the heat in to reduce coal usage, even at temperatures of -35F or colder. It provides 2-3 times the effective R-value of conventional fiberglass batt insulation.
A boiler of the efficiency you specified will save in lifetime avoided energy costs compared to your existing boiler. You could save more by buying at the required FEMP efficiency level. The minimum thermal efficiency for Federal purchases is %. Federal buyers are required to buy at the minimum thermal efficiency level unless they have a cost-effectiveness or functional exception.
Australia’s coal fired power stations use old technology and poor quality coal (Caldecott et al 2015). This is especially true in Victoria, where brown coal fuels the three dirtiest power stations in Australia. Ten of Australia’s coal power stations have already shut down over the last six years (refer to Table 1; APH 2017).
They're comparable in heating capacity and efficiency to an unflued gas heater, and typically cost a few hundred dollars. However, they are more expensive to run; one litre of fuel, costing about $3, will give roughly 90 minutes to two hours burning on a high setting. The same amount of heating with gas would cost around 50c.

The amount of input fuel depends on the fuel energy content and on the overall energy efficiency. New boilers running on coal, oil, natural gas and biomass can reach efficiencies of 85%, 80%, 75% and 70% respectively. Boiler efficiency can be improved by preventing and/or recovering heat loss.
Coal can be burned for heating or to produce electricity. To convert thermal coal to electricity, it is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. The hot gases and heat energy produced from combustion converts water into steam to run a turbine and generator  .
