The boiler is controlled by an additional wiring connection, usually a second live wire. When this wire is live, the boiler operates. 4 core flex can be used for the connection (L/N/E and switched L). Older boilers typically just had a power supply and simply operated when power was connected, and stopped when power is switched off.
01/11/2014 · Benefits of Lowering Heat Rate. The heat content of coal is in the range of 8,000 Btu/lb to 12,000 Btu/lb. Coal costs $1.5/MMBtu to $2/MMBtu, or about $30/ton.
COG contains H 2 = 60%, CH 4 = 24%, CO = 6%, CO 2 = 2%, and N 2 = 6%, but only carbon in CH 4 is oxidized in the raceway to CO releasing heat. CO 2 reacts with coke carbon to CO consuming energy, whereas H 2, N 2, and CO are only heated up in the raceway. The advantage of H 2 and CO as reducing gases comes in use in the upper part of the furnace. COG lowers the adiabatic flame temperature
