Hot water boiler parameters are the main indicators of boiler performance, including hot water boiler capacity, steam pressure, steam temperature, feed water temperature.
Hot water boiler capacity can be expressed by rated evaporation or continuous evaporation. Rated evaporation is the amount of steam produced continuously per unit of time at specified outlet pressure, temperature and efficiency. Continuous steam volume is the steam volume that can be produced continuously per unit time by the hot water boiler under the specified outlet pressure and temperature. The unit of evaporation is customarily expressed in tons per hour, and the capacity of a power station boiler can also be expressed in the electrical power (megawatts) of a matching turbo-generator.
Steam parameters include boiler steam pressure and temperature, usually refers to the superheater, reheater outlet superheated steam pressure and temperature, if there is no superheater and reheater, refers to the boiler outlet saturated steam pressure and temperature. The boiler pressure unit is expressed by MPa and also by engineering atmosphere (at). 1 MPa is equal to 10.2 engineering atmosphere.
