Boiler size calculator - What size boiler do I need

The British Thermal Unit, or BTU, is an energy unit. It is approximately the energy needed to heat one pound of water by 1 degree Fahrenheit. 1 BTU = 1,055 joules, 252 calories, 0.293 watt-hour or the energy released by burning one match. 1 watt is approximately 3.412 BTU per hour. BTU is often used as a point of reference for comparing

Boiler/Burner Combustion Air Supply Requirements and

May 07, 2021 · When you think of gas burners, ranges and cooktops likely come to mind. Calculating gas consumption in gas burners, ranges or other gas-burning appliances is fairly straightforward and can help you to estimate your fuel consumption and related costs. Smaller gas burners may have both lower costs and a reduced environmental impact, due to lower gas consumption.

Calculating Boiler Chemical Requirements – Water

The Carbon Trust recommends that a wood fuel boiler should cover 50-60% of the maximum system load; this translates to approximately 85% of the heat supplied by the biomass system. A peak load boiler (normally the existing oil/gas boiler, but it can be another biomass boiler) covers the extra capacity. Calculating your boiler size

BTU Calculator

When calculating your boiler size, you might notice two powers in the specifications of a given boiler. One is the power input, the other is power output. Input says how much energy goes into the boiler to make it work, and output says how much of that energy is converted into usable heat. Efficiency is the percentage of output from the input.

Apr 12, 2021 · Although modern boilers adapt to lower requirements. By not using the boiler calculator and guessing what size boiler you need and going larger will mean you have spent considerably more money on a boiler model that you do not need. If the boiler you choose is not upscale, you may be wasting a lot of money on burning unnecessary gas.

Industrial Boiler Efficiency Calculation & Factors

The boiler gas consumption calculation need the following parameters: such as natural gas calorific value 8500kcal/m3, pressure 8-10Kpa, and theoretically, the gas consumption of boiler heat = boiler calorific value÷ (Calorific value of natural gas x Boiler thermal efficiency)= 2400 000 Kcal / (8500Kcal * 0.94) =297m3/h, here we take 4 tons of natural gas boilers for example, then the boiler gas …


Anyway, you can choose whatever depend the actual requirement and we can meet your need. For example, The calculation formula of fuel demand for steam boiler(saturated steam boilers) is as follows: Bj=B (1-q4/100) Bj- calculation of fuel consumption, kg/h B- fuel consumption, kg/h q4- boiler mechanical incomplete combustion loss,% B=100Q/ (Qdw*) B- fuel consumption, kg/h Q- effective heat utilization of boiler, kj/h Qdw- Low calorific value of fuel, kj/kg η- boiler …


A periodic boiler flue-gas analysis is the best indicator that an adequate supply of combustion air exists. This, and any necessary burner adjustments, should be performed by a trained technician with the proper equipment to measure the amount of excess oxygen and/or carbon dioxide and ppm of carbon monoxide.
