What is the role of a zirconia analyzer? How to improve the combustion efficiency of the boiler? As people pay more and more attention to the concept and understanding of energy saving and environmental protection, protecting the environment and saving energy has become the responsibility of people or enterprises. How to reduce energy consumption and improve combustion efficiency? Select the appropriate zirconia analyzer to obtain the required analytical data.
Fuji Analyzer Measurement and Combustion Efficiency All combustion units, whether utility boilers, industrial furnaces, various burners or heating units, are designed to convert fuel into heat or electricity for production. Especially today, more efforts are being made to improve combustion efficiency and reduce emissions from pollution sources, namely NOX, SO2 and HC (incompletely burned fuels). Meet emission standards to promote ecological protection. Ways to improve combustion efficiency can be measured regularly using Fuji Portable Zirconia Analyzers, and continuous Fuji Online Zirconia Analyzers can be used to measure the oxygen content and fuel content or carbon monoxide content in flue gas to calculate excess air factor and combustion efficiency values , heat loss value and other parameters.
The function of the Fuji analyzer is to improve the combustion of the right amount of fuel and the right amount of air in the optimum ratio. There is 79% nitrogen in the air. This nitrogen does not participate in combustion, but is heated during the combustion process, absorbing energy from the flue that is released into the atmosphere. In order for the 20.9% oxygen in the air to participate in the combustion, the nitrogen must be heated nearly 4 times and then released. This loss of energy is unavoidable, but its Z can be minimized. This form of loss will be minimized if the air input can be significantly reduced while ensuring adequate fuel consumption. However, the reduction of air must be carried out on the premise of ensuring the complete combustion of the fuel, otherwise the energy loss due to the incomplete combustion of the fuel is also considerable and the atmosphere will also be polluted. Finding the Best Burning Point with a Zirconia Analyzer How to find the best burning point is the key to saving energy.
Theoretical analysis using a Fuji analyzer: the more excess air in the picture, the greater the energy loss; if the oxygen content increases, it will go with nitrogen. More energy to walk. In order to reduce energy consumption, the oxygen content in the flue must be reduced. However, if the oxygen content is reduced too much, the fuel cannot be completely burned due to insufficient oxygen content, resulting in losses, what is the appropriate oxygen content? Correct choice of zirconia analyzer Because combustion is a dynamic process, the fuel process cannot stay at the optimal point for a long time, it will inevitably change along the measurement curve, so the actual combustion point should not be the Z optimal point, because the optimal point It is too close to the large slope line of energy loss due to incomplete combustion on the left side, so the actual operating point should be slightly left, usually 0.25% O2 is better.
Oxygen, carbon monoxide, flue gas temperature, etc. are measured with a Fuji zirconia analyzer to calculate the air-fuel ratio, the air-air excess coefficient and other parameters. Depending on the actual fuel type and boiler conditions, adjust the air-fuel ratio to find the best firing point.
