Too much water in the expansion tank and too little air may also cause pressure to rise frequently. If the bottom of the tank does not feel hotter than the top, it indicates an excessive amount of water. You need to drain this water from the tank. To do so, first turn the boiler off. Then close the water shutoff valve and allow the system to cool.
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.
Modern boiler systems for home heating are hydronic systems, in which the boiler heats water for circulation throughout the house.They are closely related to steam boiler systems, but rather than circulating actual steam, hydronic systems have pipes carrying the hot water that radiates heat through either steel radiators or baseboard convectors (sometimes called "fin-tubes").
Now if the burner does not turn on when there is a call for heat, that could be because the boiler water is already hot enough that the primary control is not turning on the burner. Feel the outlet piping from the boiler and check the circultor(s) to see if hot water is circulating.
To determine if your washer is getting the proper amount of air, check for white smoke at burner ignition. A slight puff of white smoke is normal.

If the i gniter is getting voltage, but it doesn’t glow, this indicates that the igniter is defective and should be replaced.
Every pound of water in the hot gas converted to a liquid adds 1,000 BTUs into the boiler water. The dry flue losses and loss from the water vapour can be readily calculated if the amount of CO2 or 02 in the flue gas is known (this is used to calculate the dew point for the water in the flue gas and to determine the concentrations of the hot
