Aug 22, 2016· Combustion & Flue Gas Analysis 25December 2006 Excellence in measurements Analysis Methods During combustion with an excess of air λλλλ=1.1 it develops 11.5 m3 of flue gases ( for each m3 of burned gas) as : (CO2) 1.0m3 + (O2) 0.2m3 + (N2) 8.3m3 + (H2O) 2.0m3 = 11.5 m3 Analysis on Dry basis If you remove all water contents from flue gases
Combustion is a vital area in boiler control and highly coupled to the overall system efficiency and process economics. It is common to find many control loops running in manual operation, automated loops are poorlythat configured and degraded equipment for various reasons (e.g. inadequate maintenance, faulty sensors etc.)1. A typical breakdown of
key factor is fuel usage or boiler efficiency. Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units
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.
Improve Your Boiler’s Combustion Efficiency Combustion Efficiency Operating your boiler with an optimum amount of excess air will minimize heat loss up the stack and improve combustion efficiency. Combustion efficiency is a measure of how effectively the heat …
Modern flame retention burners make it possible to adjust the performance to high CO2 (or low O2) levels. For example, in certain packaged applications, 14% CO2 at a trace of smoke level is not uncommon. On the surface, this appears to be excellent because the system …
Too little oxygen results in incomplete combustion creating harmful emissions. Setting the boiler to burn with excess oxygen is the normal solution to reducing emissions. SST’s Zirconium Dioxide oxygen sensors can help customers optimise their boiler combustion efficiency within the oil, coal, gas and biomass boiler market.
5 The Combustion Process Combustion is a chemical reaction of rapid oxidation started by the correct mixture of fuel, oxygen and an ignition source. The chemical reaction for natural gas is: CH4 + 3O2 = Heat + 2H2O + CO2 + O2 Where: CH4 = 1 cubic foot of Methane Gas (Natural gas) 3O2 = 3 cubic feet of Oxygen Heat = 1027 BTU's of energy produced from the chemical reaction
The entire system (furnace/boiler, ducting, and piping) must be evaluated to determine the true efficiency of the system. Combustion efficiency is a valuable part of the system evaluation, but it is only one part of the evaluation process and cannot be used as the sole reason or justification for keeping or replacing existing equipment.
A typical burner is usually set up with 10-20% excess air (2-4% O2). NOx controls that require higher excess air levels can result in fuel being used to heat the air rather than transferring it to usable energy. Thus, increased stack losses and reduced boiler efficiency occur.
Oct 10, 2017· The boiler will operate in condensing mode, at highest efficiency, more of the time. There is a diminishing returns effect in oxygen content and performance for the unit. Too much available oxygen will lead to inefficient combustion.
