Carbon dioxide - CO 2 - is a combustion product and the content of CO 2 in a flue gas is an important indication of the combustion efficiency. Optimal content of carbon dioxide - CO 2 - after combustion is approximately 10% for natural gas and approximately 13% for lighter oils.

Get a QuoteHow can I determine the mass flow rate of steam through a boiler? I have a boiler operating at 5bar and produces saturated steam. From steam tables, the temperature is 151.9 degrees Celcius.
Get a QuoteSteam, 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.
Get a QuoteReturn the Maximum amount of Condensate where possible. Maintain a Boiler free from Scale deposits. Carry out regular Combustion Testing, every 3 - 6 months. Size and match Boilers to suite the Loads expected. Have adequate Combustion Air & pre heat air, in boiler room.
Get a QuoteIn actual practice, two methods are commonly used to find out boiler efficiency, namely direct method and indirect method of efficiency calculation. In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred.
Get a QuoteBoiler efficiency is calculated by determining the steam value per hour and dividing it by the amount of fuel which is consumed per hour. By doing this one can determine the efficiency of a boiler.
Get a QuoteOct 01, 2018· Boilers require excess air in order to complete combustion. Although necessary, the amount of excess air can result in totally different efficiencies for your boiler. Too little excess air and the boiler will build up soot and dangerous carbon monoxide, while too much excess air reduces efficiency.
Get a QuoteDetermination of steam/water parameters. Given parameters. Normally in a steam boiler design assignment the parameters describing the live (output) steam, e.g. mass flow, pressure and temperature are given. If the steam boiler to be designed has a reheat cycle, also
Get a QuoteUse boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.
Get a QuotePreheat Combustion Air. If you have a large temperature difference (20° to 40°) between your boiler intake air location and the ceiling of your boiler room and this hot air is a result of boiler and stack losses, you can increase your boiler efficiency by either extending the intake upwards or forcing the hot air down.
Get a QuoteAug 29, 2017· Boiler Efficiency Calculation: a complete guide. Then certainly there is an optimum value of the air excess to obtain the best combustion efficiency. As an illustration, the optimum value of air excess to the combustion of natural gas is 5 to 10%, liquid fuel at the rate of 5 to 20%, and 15 to 60% for coal combustion.
