How to prevent thermal equipment scale?
After thermal equipment fouling, often caused by poor heat transfer tube wall temperature, when the temperature exceeds the metal can allow temperature, it could cause bulge and pipe explosion accidents. Water boiler water slag is too much, can affect the boiler steam quality, and perhaps blocking furnace tube, threatening the safe operation of boiler. In order to prevent fouling thermal equipment, from the following several aspects: (1) try to reduce the water hardness. (2) as far as possible to reduce silicon compounds to water, the content of aluminum and other metal oxides. (3) reduce the iron content in the water of boiler, increase the iron removal equipment. (4) reduce the copper content in water, adding complexing agent to the boiler water. (5) good feed processing, to prevent corrosion.
(1) can react with other sediment in the furnace tube, become the undissolved scale; (2) because of its poor heat transfer, in some cases, may cause the furnace tube overtemperature that burn out; (3) can cause metal corrosion under the sediment.
