Boiler waste heat recovery device

Overview

Sewage discharge is an important operation in the operation of boilers, and its purpose is to discharge the sediment and impurities at the bottom of boiler water, boiler drums and headers with high salt content, so that the water quality indicators of boiler water are always controlled within the scope of national standards. Boiler blowdown is an important means to ensure that the water quality of the boiler reaches the standard requirements and prevent scaling.

Boiler blowdown is divided into two types: continuous blowdown and regular blowdown. Continuous blowdown, also known as surface blowdown, requires that part of the boiler water be continuously discharged from the highest concentration of salt and alkali in the boiler water in order to reduce the salt, alkali, silicic acid content and suspended slag content in the boiler water. Periodic sewage discharge mainly excludes sediments such as water slag and mud in the furnace, so its sewage outlet is mostly set at the lower part of the drum and the bottom of the header. The period of the regular blowdown operation is short. The sewage discharged from the boiler contains high thermal energy and is directly discharged into the ditch, which not only pollutes the environment, but also wastes thermal energy. The continuous and regular blowdown of the boiler reaches 5-10%. Therefore, the significance of recycling the thermal energy of the boiler blowdown is significant. It not only recovers part of the thermal energy, improves thermal energy efficiency, but also reduces environmental pollution. SVPW boiler waste heat recovery device is a device dedicated to recover waste heat.

Regular and continuous sewage heat recovery can be combined with one device or two devices.
