Rated evaporation capacity is the quantity of steam continuously produced per unit time under a specified outlet pressure, temperature and efficiency.
Maximum continuous evaporation capacity is the maximum amount of vapor that can be produced continuously per unit time under the specified outlet pressure and temperature. The evaporation unit is usually expressed in tonnes/hour, and the capacity of a power plant boiler can also be expressed by the electrical power (megawatts) of the corresponding turbogenerator.
A steam boiler, sometimes called a steam generator, is an important part of a steam appliance. Power plant boilers, steam turbines and generators are the main engines of thermal power plants. Power plant boilers therefore constitute important equipment for the production of electrical energy. The capacity to evaporatetion of a steam boiler when using the designed fuel and ensuring thermal efficiency according to the evaluated steam parameters and the rated feed water temperature is called rated evaporation capacity.
Detailed information
When a new boiler leaves the factory, the evaporation capacity stated on the nameplate refers to the capacity of nominal boiler evaporation. Expressed as: Boiler evaporation capacity = average evaporation rate × heated surface area. It can be seen that the evaporation capacity of the boiler depends on the evaporation rate of the boiler and the number of heating surfaces.
Steam boilers with a rated evaporation capacity of 6 to 35 t/h can be distinguished from combustion methods, mainly including chain grate boilers, reciprocating grate boilers, boilers with bubbling bed and thes circulating fluidized bed boilers. There are two. types of installation methods: assembly and bulk. Different types of boilers can be divided into saturated steam boilers and superheated steam boilers based on their steam supply parameters.
