Necessity Henan low nitrogen gas boiler combustion gas boiler several solutions Henan low nitrogen emissions, reducing NOx emissions monitoring data to improve air quality in recent years show a greater proportion of the typical characteristics of excessive contaminants appear PM2.5 long seriously overweight and regional situation, to improve ambient air quality is facing enormous challenges. Domestic and international research and management experience shows that regional PM2.5 pollution control is a very difficult system engineering, must be analyzed on a consolidated basis, we propose targeted control measures in order to effectively alleviate the region PM2.5 pollution. PM2.5 including primary and a secondary discharge section two generating particles, Beijing, for example, a high proportion of secondary particles, particularly PM2.5 weight ratio of the secondary particle contamination significantly increase over regular time periods. There are observations indicate heavy contamination with environmental changes PM2.5 NOx concentration exhibits a strong correlation, characterized in that changes in synchronization. Henan NOx gas boiler is an important precursor PM2.5, two roles in the formation process: First, the reaction of chemical components NO3- are important secondary particles; second generation photolysis chain reaction O3-, increased oxidative atmosphere, there is provided a SOx, NOx and oxidation SO42- NO3- the oxidant. California CAMQ use simulation models to cut NOx emissions once the impact of PM2.5, the result is every tonne of NOx emissions can be reduced by about 0.13 tons PM2.5. Beijing's latest research results show that the secondary particles is the main contributor to PM2.5, and there is a marked increase compared to 2000, mainly composed of water-soluble ions (53%), crustal elements (22%), organic matter (accounting 20%) and elemental carbon (3%), other unknown elements about 2%, and NO3- / SO42- ratio between the rising trend. Water-soluble ions to SO42-, NO3- and NH4 + based, the sum of the three (SNA) PM2.5 accounted for nearly 50% of the ratio of the average concentration contribution SNA is the main cause of PM2.5 pollution. Therefore, to reduce the emissions of NOx gas boiler Henan is an important task to improve the air quality of the environment.

After the daily water usage in steam boiler to produce steam also need to pay attention to them? Steam boilers purpose is to generate steam to conduct heat, but when the steam produced by the boiler equipment should not be on the matter, or to pay more attention after the steam, because this time the steam boiler will start boost, while furnace the saturation temperature of the water also began to increase. Since the temperature of the water in the rising steam boilers, gas bubbles and metal evaporation heating surface wall temperature also began to rise at any time, need to pay attention to thermal expansion and the temperature of thermal stress, because the bubble wall thickness is thick, the main heating process in the boiler the problem is thermal stress. At the same time, but also consider the overall thermal expansion problems, especially for pipe heating surface of the steam boiler because the wall thickness, length of problems in the heating process is thermally integrated for expansion, but also pay attention to thermal stresses, to prevent neglect caused the failure. Generating steam in a steam boiler and boost heating process, the temperature difference between the bubble there is a temperature difference along the thickness of the vertical wall and, when the temperature is higher than the outer wall temperature of the inner wall, the upper wall surface temperature is above the lower case, in order to prevent excessive thermal stress, the boiler must be slow step. The steam boiler ignition during bootstrapping, the operating state of the steam parameters of the boiler, the water level and the respective members is constantly changing. Therefore, in order to effectively prevent the occurrence of abnormal conditions and other hazards, be sure to arrange professional staff to closely monitor a variety of changes in the meter indication. By adjusting the control pressure, some of the process parameters of temperature, the normal water level in the range of the allowable, but also the reliability of the assessment, a variety of security instruments, valves and other components, so as to ensure adequate safety and stable operation of the steam boiler . The higher pressure steam boiler, energy consumption will be higher and higher, the corresponding steam pressure equipment and piping, and the valve will also increase accepted, which also makes maintenance protection boiler steam demand is relatively increased, and steam generated in the heat generation and transport processes and also increase the proportion wandered. High pressure steam mouth of salt will increase with increasing pressure and that the heated area of ​​the waterwall tubes salt, smoke tubes and the like drum phenomenon generating structure, resulting in overheating foaming, clogging phenomenon, can cause severe pipeline explosion and other dangerous accidents.
