Minimum air amount and the relationship between the excess air coefficient in the dew point of the flue gas for complete combustion of the fuel required under ideal conditions, said theoretical combustion air amount, the fuel for complete combustion in the actual conditions of incomplete combustion, or the actual amount of air required amount of combustion air . Excess air coefficient = actual combustion air amount / theoretical combustion air amount. Dew point (Dewpoint), also known as the dew point temperature (Dewpointtemperature), in meteorology fixing means under pressure, gaseous water contained in the air is condensed into liquid water saturation dropped to desired temperature. At this temperature, condensed water mist floating in the air is called, while the stick is called on a solid surface exposed, hence the name dew point. Excess air and flue gas dew point relationship when there is insufficient combustion air ratio of the fuel is not sufficiently low combustion efficiency, perhitungan kapasitas hopper pada boiler 3 2 ton efficiency is also reduced. When the excess air, the flue gas water vapor partial pressure decreases, the dew point temperature is low, it can not lead to condensation, latent heat can not be released, and the excess air factor will take a lot of heat, so that the boiler efficiency decreases. Therefore, when an excess air ratio of 1.2 to 1.3, to achieve complete combustion in the excess air coefficient is very small, almost chemically incomplete combustion phenomenon. When the air excess factor is 1.2-1.3, both to ensure that the dew point will not be too low (the condensation effect is very significant), but will not take away the excess air ratio in the flue gas waste heat large, which can greatly enhance the thermal efficiency of the boiler .
To ensure the safety of special equipment such as perhitungan kapasitas hopper pada boiler 3 2 tons, in normal use, to further promote the comprehensive management of environmental pollution, since April this year, Khorgas Market Supervision Administration of Quality Supervision Bureau for the joint Yili area within the jurisdiction of Khorgas , launched a special safety inspection activities boilers.
Law enforcement officers to be included within the jurisdiction of the major hazard of 12 boiler units of a total of 21 boilers individually conduct a special inspection, focus on examination of the "three implementation, two certified, a test, a plan," the implementation of a detailed view of boiler safety management system, run records.
Test results showed that most of the boiler unit security management more standardized, but there are still some units use boilers run records were incomplete, part of the boiler has to inspection cycle, has been scrapped or dismantled boiler is not write-off and other issues, law enforcement officers to issue on-site boiler sealed, and ordered boiler unit for rectification.
Sample analysis to be followed by furnace water, water quality compliance confirmation stop rinse off for each hydrophobic, sewage valve. The slow water to the perhitungan kapasitas hopper pada boiler 3 2 ton, the level control up to standard. Gray also appropriate to open each door and each boiler front door oven, and remove moisture to the furnace.
Condensing perhitungan kapasitas hopper pada boiler 3 2 ton thermal efficiency and Application Analysis: as compared to coal-fired boiler gas boiler greatest feature is significantly reduced emissions, almost no sulfur dioxide, nitrogen oxides, and carbon dioxide emissions were reduced by 45% and 52%; In addition, each of the combustion gas may 1g 2.25g produced water, water vapor in the flue gas volume composition ratio reaches 15% ~ 19%, which is 2 to 3 times the data coal-fired boilers. All the water in the boiler evaporate into water vapor with the flue gas emissions and take away a lot of latent heat of vaporization, which is the root cause of hair high and low natural gas heat difference 3700kJ / Nm3 of. Recovery of this part of the latent heat of vaporization is the most important way to improve the thermal efficiency of the gas boiler. Condensation core technology is to reduce the heat loss of the fuel combustion, efficient absorption of thermal energy generated by the fuel, and because the flue gas condensation in the flue gas to the condensed water collecting harmful substances, acidic substances and reduce other contaminants in the air emission.
