Boiler What are the specifications?

Boiler specifications indicate the ability and level of the boiler to produce steam or heat water. The specification of the steam boiler is expressed as the quantity of steam generated per unit time and the steam parameter, and the specification of the hot water boiler is expressed as the quantity of heat absorbed by water and the hot water per unit time.

The amount of steam produced per hour in a steam boiler is called the boiler's evaporation, also known as the capacity or output of the boiler. It is usually indicated by the symbol "D" in t / h (tonnes / hour). The evaporation on the nameplate of the boiler is usually the rated evaporation, which is the maximum evaporation that the boiler must guarantee for continuous operation at the specified steam parameters and feed water temperature.

The capacity of a hot water boiler is the amount of heat absorbed by the boiler in a unit of time, expressed in megawatts (MW), and its rating is the rated thermal power or rated heat.

The amount of heat produced by the boiler steam and the medium is directly related to the number of heated surfaces of the boiler. The heating surface is separated from the boiler flue gas and water vapor, and the heat from the former to the latter metal wall, usually pipe or cylinder wall.

Steam boiler steam parameters to the main boiler steam outlet steam pressure (gauge pressure) and temperature. The parameters of the hot water boiler to the rated water pressure (gauge pressure) and rated water / inlet temperature. Pressure and temperature, respectively, the symbol "p", "t" said.
