Boiler specifications

There is no refractory brick wall in the furnace of corner tube boiler, which is heated evenly. The membrane water-cooled wall produced by international standard, which has small thermal stress and fast heat transfer. Therefore, this type of boiler has rapid start-up, rapid temperature rise and strong adaptability to load change. There is no refractory brick wall structure in the furnace, which reduces a large amount of heat storage. The grate frame is reasonably designed, especially the cast iron structure is used in front of the frame supporting the driving shaft, which effectively ensures that the driving shaft will not shift locally under various loads. The whole boiler is welded together by the membrane water-cooled wall, and the ball which can be freely shifted is installed at a certain angle at the pivot point on one side of the boiler, which can avoid the damage of thermal stress caused by the thermal expansion and contraction of the boiler.

The boiler specification indicates the ability and level of the boiler to produce steam or heating water. The specification of a steam boiler is expressed in terms of the amount of steam generated per unit time and steam parameters, while the specification of a hot water boiler is expressed in terms of the heat absorption amount of water per unit time and hot water parameters.

The amount of steam generated by a steam boiler per hour is called the boiler's evaporation capacity, also known as the boiler's capacity or output. It is usually represented by the symbol "D", and the unit is t/h. The evaporation capacity on the boiler nameplate is usually the rated evaporation capacity, which is the maximum evaporation capacity that must be guaranteed during continuous operation of the boiler under specified steam parameters and feedwater temperature.

The capacity of a hot water boiler is the amount of heat absorbed by water in the boiler per unit time, in MW, and its rated value is called rated thermal power or rated heat supply.

The amount of steam produced and heat absorbed by the medium in the boiler is directly related to the number of heating surfaces in the boiler. The heating surface is a metal wall in a boiler that separates flue gas and water vapor and transfers heat from the former to the latter, usually a tube or cylinder wall.

The steam parameters of a steam boiler are expressed by the pressure (gauge pressure) and temperature of the steam at the outlet of the main steam valve of the boiler. The medium parameters of a hot water boiler are expressed in terms of rated outlet pressure and rated outlet/inlet temperature. Pressure and temperature are indicated by the symbols "p" and "t", respectively.
