Steam Calculators: Boiler Calculator

17/3/2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Making sense of boiler ratings - HPAC Magazine

16/8/2017 · For example, if we have a natural gas boiler with an input rating of 100,000 Btu/h and a heating capacity of 85,000, we would have a steady state efficiency of 85 per cent. This steady state can only be measured when the boiler is at full load and all the conditions, such as return water temperature, air temperature, air/fuel ration, and so on remain constant.

Water-tube boiler - Wikipedia

Water-tube boiler. A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in

Boiler size calculator - What size boiler do I need? | Heatable

28/5/2021 · Choosing a suitable size boiler is super important for two key reasons: #1 - It won't meet your homes heating requirements if you undershoot it. An underpowered (undersized) central heating boiler will struggle to meet the heating demands of your home, resulting in a shortfall of heating to your radiators, hot water to your taps/shower or worse – both.

Boiler Capacity - Engineering ToolBox

Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW)
