Steam coal, also known as thermal coal, is used in power stations to generate electricity. Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. In these pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high
Fuel costs dominate the total cost of operation for fossil-fired power plants. For renewables, fuel is generally free (perhaps with the exception of biomass power plants in some scenarios); and the fuel costs for nuclear power plants are actually very low.

The electrical generating facility consists of four pulverized coal, dry-bottom, tangential-fired boilers that primarily fire subbituminous coal which can produce up to 600 megawatts of electricity. The boilers fire distillate oil during various startup modes. Boilers 1 and 2 each have a maximum heat input of 922.2 mmBtu/hr and exhaust combustion
A comparison of fine particulate emissions (3 μm or smaller) based on mass per unit of stack gas between the two boilers, as presented in Table 5, suggested that more fine particles were released from the cyclone equipped oil fired boiler than from the precipitation equipped coal fired boiler. Results of pH and acidity analyses of ash samples
Our engineers developed an automatic stoker unit equipped with a coal hopper that held enough fuel for several days. This allowed the coal to be cleanly burned and without frequent maintenance. They then saw the need to make a hot water boiler specifically designed to burn coal and built them in multiple sizes to meet our customers' needs.

I agree with both Sting and Yanche about the size of the pipe, BUT from a practical standpoint, the 1" pipe is more than adequate.. The upgrade of the circulator pump to push hot water through a 1" pipe compared to a 1.25" or 1.5" pipe is minor, in fact if you want to push the higher volume through a larger pipe you would need to upgrade the circulator pump for the larger pipe, just like you
