Methods of slowing down the rate of boiler scaling

Abstract

The invention discloses a method for reducing the boiler scaling rate. The method specifically comprises the following steps: S1, a variable frequency water pump is mounted in front of a water inlet of a full-automatic water softening device, the frequency of the variable frequency water pump is set to be 32 Hz-40 Hz, so that the water inlet pressure of the full-automatic water softening device is 0.30 MPa-0.38 MPa; S2, to-be-treated water enters the full-automatic water softening device through the variable frequency water pump; and S3, softened water treated by the water softening device enters a boiler. According to the method, resin can recover the original exchange and treatment capacity after regeneration, the aging rate of the resin can be slowed down, the water softening capacity of the full-automatic water softening device can be uppermost, finally, the quality of the softened water is improved, the rate of scaling in the boiler is reduced, the heat-transfer property and the thermal efficiency of the boiler are improved, and fuel energy waste is reduced.

Description

technical field [0001] The invention relates to the field of boiler equipment, in particular to a method for slowing down the scale rate of boilers. Background technique [0002] In order to slow down the scaling rate inside the boiler, a fully automatic water softening device is usually used to provide national standard soft water (the hardness standard of the soft water is less than or equal to 0.04mmol / L) as water for the boiler. Since the national standard soft water treated by the automatic water softening device is only relatively softened, it is difficult to slow down the fouling rate inside the boiler by this only method. According to the usual use and maintenance records of the boiler, we found that the current single method of only relying on the automatic water softener to provide national standard soft water as boiler water to slow down the scaling rate inside the boiler has the following disadvantages: [0003] (1) The water quality of the soft water produced b...
