Making sense of boiler ratings - HPAC Magazine

16/8/2017 · The input is also used to determine the efficiency of the boiler for example; a boiler with an input of 150,000 Btu/hr and a gross output of 135,000 would have an estimated combustion efficiency of 135,000÷150,000= .90×100=90% eff. Next we have the boiler output, which can be listed in several ways. Which one to use is really dependant on the

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.

Condensing boiler output | Screwfix Community Forum

10/3/2015 · I am going to have an old boiler replaced by a condensing gas combi boiler. It's in a small house, the total heating load, 5 radiators, is only 7 Kw so a small boiler of about 25Kw output would suffice. However, because I would like to be able to fill a bath in a short time, I am considering having a larger boiler fitted, about 30Kw or even bigger.

Boiler Efficiency

The output specifications for a boiler will often show the maximum flow rate that the boiler can provide at a specific temperature. For example, you might see a flow rate of 12 l/min at a temperature of 40 degrees centigrade. This is how much water it can send out to the taps in your home at that temperature.

13/5/2010 · May 12, 2010. #3. Heat input is how much energy you put into the boiler to get its output. So due to efficiency losses you might find a boiler with a 20kw output has a heat input of say 22kw. If you have sized a house and need 20kw you would be looking for a boiler with an OUTPUT of 20kw. Most boiler manufacturers quote outputs.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
