Conversely, as steam demand increases, drum pressure decreases, and the gas bubbles expand, often causing the drum level to appear to increase. To help compensate for shrink and swell, boiler control engineers employ three-element control strategies that simultaneously look at steam flow, the rate feedwater is flowing to the steam drum and the
Jiangsu Runli Boiler Co., Ltd is specialized in designing and manufacturing the steam boiler, thermal oil boiler and waste heat boiler in 6 series, such as coal burning, oil (gas), Coal Water Mixture, firewood, saw dust (grate boiler) and electric heating, the heating load varies from 0.5tons to 75 tons per hour.
Radiant boilers feature a single drum construction to overcome various limitations posed by bi-drum boilers for high-pressure applications. Steam Generator The heat exchanger used in some reactor designs transfers heat from the primary (reactor coolant) system to the secondary (steam) system.
In single drum boilers, the furnace is made very tall to absorb the additional heat load required because of the absence of the boiler bank. Boiler Bank: Boiler bank absorbs heat from hot gases through convection. Usually Boiler bank is bulky as it has to absorb heat by convection at relatively low temperature.
