Boiler scale remover

Boiler scale remover is a valid removal of boiler scale and other impurities supplies, widely applied to various large boilers which, to save costs, provide efficiency, let's look at a simple to use boiler descaling. Detergents For operating pressure ≤13 kg / cm, evaporation no less than boiler economizer and superheater 4 t / h. Detergents before use with hot water 80 ℃ dissolved into a solution of 20% concentration. Then to boiler water filling to the lowest visible level, then the solution was injected into the furnace of open and maintain a high level. Then the ignition temperature, cook stove. Cook stove operation sub atmospheric and under pressure in two ways. When pressure cooking stove, oven until boiling water, boiling water over low heat and keep the furnace, the furnace pressure was raised to 1 kg / cm squared for some time (duration less than 24 hours). Then depressurized. Stop after cooking stoves, to gradually sewage and water, the furnace temperature to slow down to avoid causing residual stresses, when the boiler water temperature dropped to about 50%, only water. Pressure cooking stoves, the boost to slow, generally about 24 hours with the pressure rose to 50% of the working pressure and then maintaining the temperature and pressure, to maintain this state for some time (duration less than 24 hours). When cooking stoves run continuously day and night. Do not discharge during the cook stove, do not use steam, so as not to affect the results, the cooking oven to keep the water level at the upper limit of the table and found to reduce the water level, it is timely replenishment. During the cooking stove to have someone on duty, be careful to check the boiler parts and valves for leaks and other abnormal phenomena, even if action. After cooking stoves, water is done in time to open manholes, hand holes, inspection holes by hand or pressure hose to wash away the slime extremely remaining on the steel scale, otherwise difficult to remove hardened dirt back again. Oven cooking time of less than 72 hours. Use boiler descaling is very simple, just install the above operations can easily complete the work requirements.
