METHOD FOR CONTROLLING HEATING OF HEATING BOILERS WITH REDUCTION OF PARAMETERS OF STREAMS OF MEDIUM IN STEADY STATE

摘要

FIELD: power engineering.;SUBSTANCE: method of controlling heat output of heating boiler houses without controlling the water temperature at the inlet of the boiler is currently used. This leads to unstable condition of medium flows both in heat network, and in boiler itself and reduction of efficiency of exit gases. Not controlling of water temperature before the boiler has also led to non-creation of conditions for automatic control and reliable measurements. Aim is achieved due to the boiler boilers output capacity control by the water temperature control at the boiler inlet with achievement of the steady state and effective temperature of the outgoing gases. Adjustment of medium flows into steady state is applicable for all engineering systems of utilities, power supply, gas supply, industry, transport and agriculture.;EFFECT: disclosed is a method of controlling heating of heating boiler houses with bringing parameters of medium flows into steady state; invention can be used to control the capacity of heating boiler houses during tempering of heat supply systems with open and closed water intake.;1 cl, 39 dwg
