How to calculate the sewage rate in boiler water
The amount of water and the amount of effluent are expressed as relative values, ie, the evaporation is 100%, the emission rate is expressed by P, and the water supply is (100 + P).
The amount of sewage can be calculated by the balance of the impurity of the pot, that is, the amount of impurities brought by the feedwater into the boiler should be equal to the sum of the mass brought out by the steam and the amount of impurities mixed with the effluent. According to this relationship,
The continuous discharge of the boiler is called the amount of sewage, which accounts for the percentage of boiler evaporation.
Boiler sewage will bring the loss of working fluid and heat, for which the boiler emissions that the sewage rate should be limited.China's relevant regulations, condensing power plant sewage rate of 1% - 2%; heating power plant pollution rate
