Optimizing Boiler-System Efficiency | HPAC Engineering

Control is critical. In a facility with several large gas-fired boilers of various sizes and configurations, four boilers were operating in the 30- to 50-percent load range as standard procedure. System-pressure control was crucial. Older boiler controls could not maintain header pressure and drum level with fewer units operating at higher load.
