The purpose of boiler blowdown is to control solids in the boiler water. Blowdown protects boiler surfaces from severe scaling or corrosion problems that can result otherwise. There are two types of boiler blowdowns – continuous and manual. A continuous blowdown utilizes a calibrated valve and a blowdown tap near the boiler water surface.Get Price
Fired boilers that are most prevalent in industry are either fire tube boilers or water tube boilers. 4.2.2 Fire Tube Boiler A fire tube boiler consists of a drum with a tube sheet on each end in which the fire tubes are fastened. Water is contained within the drum surrounding the fire tubes.Get Price
Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.Get Price
Let's talk about a potentially serious problem that is sometimes overlooked… thermal shock in your steam boiler.
