It needs to be around 250 to 300 gallons for each 100,000 BTUh maximum fire output of the boiler, and should have its own circulator -- possibly with a high limit aquastat on the boiler (circulator on at 190). The tank itself need not be pressurized; you can use a heat exchanger such as might be found in an indirect hot water tank.

Our first combustion system dates back to the 1950’s and had a 2 megawatt water-cooled inclined grate for biomass firing. Thanks to our experience with in-house water circulation, the combustion system was integrated into the boiler’s natural circulation to achieve optimal cooling of all components exposed to high temperatures.

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.

Conventional PF coal-fired boilers, currently being used in the power industry, use air for combustion in which the nitrogen from the air (approximately 79% vol) dilutes combustion products such as CO 2 and water vapor in the flue gas. During oxyfuel combustion, a combination of oxygen (typically of greater than 95% purity) and recycled flue gas is used for combustion of the fuel.
