In order to prevent the occurrence of secondary combustion horizontal boiler factory tail, which is a fundamental measure to prevent combustible material deposited in the rear of the boiler. For this reason, when the ignition, if the point does not fire, must immediately stop the supply of the fuel (e.g., coal, oil, gas, etc.) into the furnace, to prevent the combustible matter into the rear of the boiler. In operation, the soot blowing should be strengthened, with the wind appropriate, complete combustion, no black smoke. After the shutdown, monitor the temperature economizer, if the sudden increase in tens of degrees, already causing spontaneous combustion, fire-fighting measures to be taken immediately.
The level of development of the industry and domestic and international comparative analysis gap - burners, horizontal boiler factory and burner systems to control and standardization in foreign countries, the company has successfully developed and promote the use of conventional fuels, including premixed combustion, low NOx combustion technologies, including and unconventional fuels one-piece, split burner products, the largest single power split reach 93MW, monolithic reached 14MW. By using an external flue gas recirculation techniques, internal flue gas recirculation techniques, staged combustion air or fuel staging techniques, flue gas denitrification technology, premixed combustion technology + flameless combustion, the burner nitrogen oxides (of NOX) and boiler nitrogen oxide emissions to a minimum of about 5 / 10mg / m3. Technological development burner of a relatively short history, only five, six years, although from the beginning of imitation but higher than in Europe and other industrialized areas starting point, "five-second" period is entering the period of rise development, product varieties increased rapidly, product quality has greatly improved, especially the steady growth of production and application of non-conventional fuel burners. But it is undeniable, domestic and foreign brands burner there is a certain strength of the gap: ① low NOx combustion with low nitrogen emissions burner domestic enterprises has just begun to address, because there is no boiler manufacturers involved in this industry burner, and more Needless to say, carry out research and development of low NOX burner. ② R & D capabilities in the oil and gas burner and means in Europe and other developed countries, each burner manufacturers have their own R & D test center, and provided strong support for the development of the burner technology. Looking at the top ten manufacturers of our country, in addition to individual enterprise and some simple test bench, most lack a comprehensive, scientific instruments and test equipment as well as related technical professionals in research and development. In a related colleges and universities is also a lack of such research tools. ③ in the production of marketing products overseas burner large burner vendors have implemented mass production, from procurement and manufacturing cost control and marketing and other parts have a very big advantage, resulting in domestic conventional fuel burners competition in the market force is obviously inadequate, domestic burners companies are non-standard products as a breakthrough in the market, it is difficult to form large-scale production.
Henan horizontal boiler factory which measures to reduce soot integrity of the well-known and reliable Henan boiler manufacturers, provides a number of high-quality, durable oil-fired boiler according to market and customer needs, we know that the boiler combustion direct impact on the economic benefits of the unit, and the air quality of the environment . In order to improve the thermal efficiency of the boiler, reducing the amount of smoke and reduce dust, what measures can reduce dust Henan boiler there? First, to ensure adequate supply of air we know that the ratio of carbon dioxide is the carbon dioxide content of flue gas volume to the total volume of fuel in Henan boiler combustion under normal circumstances, the volume of carbon dioxide in the flue gas is constant, and the flue gas the total volume affected by the amount of air, no doubt increase in the amount of air is bound to the carbon dioxide content of the flue gas reduced accordingly, thereby reducing the soot, so to supply the appropriate amount of air. Second, the furnace temperature to maintain a certain temperature and excellent combustion temporal quality Henan boiler fuel is burnt, an important condition for soot, and the combustion of each boiler is generally suspended combustion, it is the central temperature of Henan boiler furnace is desirable to control more than a thousand degrees, but also to ensure there is enough fuel residence time in the boiler, so only in order to completely release heat and smoke reduction. Third, the amount of adjustment of fuel and air flow when the boiler load Henan vary widely, with different pore sizes may replace atomization natural oil is increased or decreased, to reduce dust, while within a certain range, as the wind amount of oil fog mixed with the air will be improved, thus contributing to burn, but if the wind increased volume will increase heat loss, resulting in increased coke dust tail, so users should timely adjust the air supply. Therefore, in order to promote complete combustion of fuel, to reduce the amount of smoke, reduce dust, the purpose of breathing clean air, not only to properly regulate the air distribution to ensure the right amount of air supply, but also to maintain a certain high Henan boiler furnace temperature and combustion time, Further, in the air blowing operation should be adjusted according to the amount of fire nozzle, and a carbon dioxide content of flue gas.
