how much does boiler installation cost in 2019
About sewage treatment how much does boiler installation cost in 2019, you should know something: a boiler blowdown purpose: to make the water in the pot of water boiler in compliance with the standards, reduce the adverse effects to the boiler scale formation caused by the impurities in the water is maintained at a certain concentration, need by continuously to the boiler to exclude large salt, alkali boiler water and deposited residues, sludge and various types of precipitates, maintaining safe operation of the boiler, to extend the life of the boiler. Second, boiler blowdown mode: continuous blowdown boiler blowdown and regular sewage into two kinds. 1, continuous blowdown Purpose: continuous blowdown portion of the salt may be excluded substance dissolved in water pot, the pot in order to maintain a controlled amount of salt contained in the water and alkalinity, to prevent excessive concentration affects the quality of the boiler steam production. Installation site: general continuous sewage outfall 200-300 mm drum mounted normal water level, boiler water was concentrated by continuous heating, the salt water of the surface layer into the furnace together, even on the exhaust port installed in the boiler water up to the salt content locations, to discharge a high concentration of salt, a new water treatment. The discharge time of: continuously discharged blowdown rate: typically about 1% of the amount of evaporation boiler. Location discharge: discharge sewage generally lead to expansion device connected by the drum. Numerous continuous shot from the boiler is saturated with water produced by the boiler at the operating pressure, a higher temperature; if a sudden drop in pressure, the vaporization point of water is lowered, so that the original saturation is destroyed, a portion of the water from the tank to become the new pressure superheater heat saturated water, the latent heat of evaporation portion of the water becomes steam. This evaporation is called flash evaporation. Continuous blowdown is to obtain a secondary steam using the principle of flash evaporation. So as to achieve recycling. 2, regular sewage purposes: periodic sewage mainly excluded rusty, desalting entirely calcium, magnesium and other flocs. And reduce the extent attached to the boiler wall and improve the use of the boiler thermal efficiency. Generally intermittent, also known as intermittent sewage or sewage bottom. Installation site: Regular Blowdown nozzle generally located at the lowest point of the BCP. Emission Time: time given row is discontinuous, generally selected from the group of emissions at low boiler load, the exhaust emissions from large given, generally only a short time it is possible to achieve the purpose of sewage discharge, typically 0.5-1 minutes, particularly by the boiler water quality may be, but should avoid prolonged given row so as not to affect the normal boiler water circulation. Chemical run on a regular basis to work after the election in each night. Blowdown rate: 0.1% -0.5% General boiler evaporation. Emission Location: the water from the bag is introduced to the expansion of a given row. After decompression, and secondary steam expansion separated waste hot water. Secondary steam into the atmosphere or utilized as a heat source, waste hot water through the general sewage into the sewer system cooling pool. Boiler blowdown water and saturated with water at the same pressure and the working pressure boiler, before the throttle valve is provided with periodic blowdown pressure is reduced, so that the periodic blowdown expander expansion cooling, secondary steam is separated.
