How to reduce the combustion temperature gas fire tube boiler in between 40 sec Henan conventional low NOx combustion technique is mainly about how to reduce the combustion temperature to reduce thermal NOx generation undertaken Henan gas boiler main techniques include staged combustion, premixed combustion, flue gas recirculation, catalytic combustion porous media and flameless combustion. A, or fuel staging combustion air staging combustion thermal NOx generation largely depends on the combustion temperature. The equivalent ratio of the combustion temperature in the case where 1 is the highest, burned under lean or rich combustion cases, the combustion temperature will be much lowered. Using this principle has developed a staged combustion technology. Henan air staged combustion of gas boiler is a fuel rich combustion of the first stage, the second stage addition of excess air, the combustion is lean, the cooling air is added between the two to ensure that the boiler will not be too high combustion temperatures. Combustion air staging and fuel staging combustion contrary, with the first stage fuel lean combustion, fuel is added in the second stage so that the equivalent ratio required value is achieved. These two methods will eventually cause the excess air ratio of the entire system to maintain a constant, low nitrogen currently widely used as combustion control technique. Second, the premix lean premixed combustion technology Henan boiler combustion gas refers to fuel and oxidant completely mixed at the molecular level before the mixture is ignited. For controlling the generation of NOx, this technique has the advantage of controlling the combustion temperature can be achieved by fully controlling the equivalent ratio, thereby reducing thermal NOx formation rates, in some cases, partially premixed and the premixed combustion than non-premixed 85% -90% of combustion to reduce NOx production. Further, the premix can also be reduced completely to reduce the excess air ratio due to unevenness caused by generation control of NOx. However, premixed combustion technology there are still unresolved technical difficulties on the security control: First, because of its highly combustible premixed gas may cause tempering; the second is too high excess air ratio will lead to an increase in exhaust losses , reduces the thermal efficiency of the boiler.
Adjusting the temperature of the hot water fire tube boiler in between 40 sec: boiler unit according to local circumstances, the development of the boiler water temperature and outdoor air temperature curve, the amount of combustion operation timely adjusted according to the corresponding relationship between the predetermined water temperature and outdoor air temperature, water temperature requirements of the network management system and the predetermined temperature by no greater than 120 ℃. To change the water temperature gradually, increased or decreased water per hour of not more than 20 ℃.
Related Questions More Answers Below. In fire tube boiler the flue gases flow in the tubes and water flows from the shell. The heat is exchange form the gases to water through convection. In water tube boiler, water flows from the tubes and the flue gases from the shell or passes over the tubes. This is the key difference between these boilers.Online chat
Fire tube boilers are useful for small demands of steam and water tube boilers are useful for industrial level usage.
