Boiler Operation Sequence - Fix it with our Plumbers Fault
Check the boiler stack temperature. If it is too high (more than 150°F above steam or water temperature), clean the tubes and adjust the fuel burner. Inspect all boiler insulation, refractory, brickwork, and boiler casing for hot spots and air leaks. Repair and seal as necessary. Replace all obsolete or little-used pressure vessels.

Gas valve ramps up to range rated set pressure (Controlled via the thermistor and potentiometer at p.c.b) Boiler control thermostat or room thermostat is satisfied or the timer shuts down the boiler. Fan and pump over run continue to dissipate residual heat (over run
Heat Value of Fuels Application of Thermodynamics in Boilers• The burner flame radiates heat to all heat exchange surfaces in direct sight of the flame • Heat passes through the steel heating surface by conduction • The heat is transferred into the water by convection • Evaporation transfers useful heat into the steam to do the work Combustion Combustion ProcessCombustion is the rapid oxidation of fuel
Both gas and oil fired boilers use controlled combustion of the fuel to heat water. The key boiler components involved in this process are the burner combustion chamber heat exchanger and controls. The burner mixes the fuel and oxygen together and with the assistance of an ignition device provides a platform for combustion.
