Coal, coke and breeze are important fuels for the paper, chemicals and primary metals industries. The other energy inputs, residual oil, distillate oil and liquefied petroleum gas (LPG), represent less than 5 percent of industrial boiler inputs. The average capacity factor for industrial boilers is 47 percent.

Whether you need to heat a home or a commercial building, the Pennstoker 7710 has the capacity to fulfill your heating needs (up to 3,000 square feet).
The decline in U.S. coal generation reflects two fundamental trends: (1) a decline in the average utilization rate (or capacity factor) of coal-fired power plants; and (2) a reduction in the total amount of coal capacity due to retirements. Less capacity, running fewer hours, translates to fewer megawatt hours delivered to the grid.

Understanding Coal Power Plant Heat Rate and Efficiency Proposed U.S. standards for reducing carbon emissions from existing coal-fired power plants rely heavily upon generation-side efficiency
Mapped: The world’s coal power plants Since 2000, the world has doubled its coal-fired power capacity to around 2,045 gigawatts (GW) after explosive growth in China and India. A further 200GW is being built and 300GW is planned. More recently, 268GW has closed due to a wave of retirements across the EU and US.
DZL chain grate coal boiler, automatic coal feeding system. DZH manual type coal or wood fired boiler, lower cost for use. SZL water tube coal boiler, large stove water tube sturcture boiler, capacity in 1-50Tons.
So you get enthalpy for 1 tph.every coal has GCV that is gross calorific value.For every grade there is different GCV. As efficiency of furnace is 85–90% that means ratio of heat consumed to form steam by heat given by coal is 0.85–0.90. so find the heat that is given by coal.
According to the U.S. Energy Information Administration, 27 gigawatts of capacity from coal-fired generators is to be retired from 175 coal-fired power plants between 2012 and 2016. Natural gas showed a corresponding increase, increasing by a third over 2011. Coal's share of electricity generation dropped to just over 36%.

DZL series package boilers are horizontal three-pass water & fire tube boilers with a chain grate stoker structure. Threaded pyrotechnic tubes are arranged in the drum to form a convection heating surface, while the drum and the water walls on both sides form a radiation heating surface in the furnace.
As an example consider these facts for typical coal fired power plant of capacity 500 MW. Around 2 million tons of coal will be required each year to produce the continuous power. Coal combustion in the boiler requires air. Around 1.6 million cubic meter of air in an hour is delivered by air fans into the furnace.

efficiency and capacity of boilers Two of the most important operating factors entering into the consideration of what constitutes a satisfactory boiler are its efficiency and capacity. The relation of these factors to one another will be considered later under the selection of boilers with reference to the work they are to accomplish.
Capacity factor. Boilers designed for base load are expected to have an inherently higher heat rate if they are operated at a much lower capacity factor than they are designed for, and many coal boilers are being operated well below their originally intended capacity factors. The effect of capacity factor is explored in this paper. 5. Other
