2016/7/29 · DEFINATION OF BOILER: A boiler is an enclosed container that provides a mean from heat of combustion to be transferred to the working medium (water) until it become heated or convert in steam. The heated steam can be utilized for transferring the heat in several processes that consume the heat of the stream and turns in work or just to heat another substance.

Consulting - Specifying Engineer | Cost-effective boiler system retrofits

2010/2/15 · Many steam boilers are controlled by a thermostat with a tight span setting, which causes the boiler to cycle on and off frequently in response to small deviations from the setpoint. Short cycling also can be caused by pressure controls with cut-ins set too high (for single pipe steam they should be set to 0) and cutouts set too low.
