The pressure range of the boiler is about 0.7 MPa to 2 MPa and efficiency is 65 to 70%. Fuel in these boilers is added into the grate which heats the gases. Hot gases enter the front section of the boiler and leave the boiler from the back and then enter the bottom flue and start moving to the front section of the boiler.

In most cases, when boiler pressure is too high it is not dangerous. In fact, most boilers that become over-pressurized will shut down either because of the pressure release valve or simply because it cannot manage the strain. While boilers can certainly explode, this won't typically happen because of elevated pressure in the system.
