The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.
Boiler horsepower - a power unit from the 19 th-20 th centuries - was used to rate the capacity of a boiler to deliver steam to steam engines.. A common definition of one boiler horsepower is the amount of energy required to produce 34.5 pounds (15.65 kg) of steam per hour at pressure and temperature 0 psig (0 bar) and 212 o F (100 o C) - with feed water at pressure 0 psig and temperature 212 o F.

Steam drum—the top drum of a boiler where all of the generated steam is collected before entering the distribution system, p. 293. Steam trap—a device used to remove condensate or liquid from steam systems, p. 294. Superheated steam—steam that has been heated to a very high temperature so
Efficiency of steam boiler is defined as the ratio of heat utilised by feed water for conservation into steam to the heat released by the complete combustion of the fuel in the same time.This is known as the thermal efficiency of the steam boiler. In the above equation, m a = Actual evaporation in kg per kg of fuel burnt. H = Enthalpy of 1 kg
Boiler efficiency is a measure of the goodness of the chosen process and equipment to transfer combustion heat to the heat in steam. Boiler efficiency can be defined as the ratio of the useful heat output to the total energy input. (3.1) η = Q abs Q in. where. η is boiler efficiency.

BTU/hr is a measurement of heat energy transferred per unit time, in this case 1 hour. Specific Heat. Specific Heat is the intensive property of a material's heat capacity, or the amount of heat required to result in a unit change in it's temperature. The specific is identified by dividing the heat capacity by the mass of a sample material.

The saturated steam from our boilers can be controlled as to pressure, which will vary the temperature and BTU transfer of the steam. We offer a variety of models from 1.5 to 750kW with carbon steel pressure vessels and 1.5 to 120kW in all stainless steel design to match any steam …
The boiler is capable of generating steam in the range of 20-40 bar pressure and the rate of steam generation is about 200 kg/hr. There are different types of Babcock and Wilcox water tube boilers. In some cases, the rate of steam generation may be 4000 kg/hr. Generally, these types of boilers are used in medium-size thermal power plants.

However a residential steam boiler pressure is so modest (0.2 psi to 0.5 psi) that the temperature increase above 212 °F will be no more than about 220 °F. A commercial boiler system heating a high-rise building may be operating at much higher pressures, perhaps 20 to 40 psi in order to be able to force steam to 20 or 40 floors of building
