If a single burner extinguishes, there may also be a deviation in the center of the furnace flame, and the air pressure of the extinguished burner may change. If the fuel supply is interrupted, the oil pressure or pressure indication of the extinguished burner may decrease to zero, while the fuel and gas pressure of other operation burners may rise. After the occurrence of the above situation, the condensing technology domestic boiler guide must be handled in a timely manner to ensure the safety of use.

Startup condensing technology domestic boiler guide steam temperature does not mention how high do? A: In the unit to start the process, often encounter steam pressure has reached the requirements, and the steam temperature was too much difference, especially in front of the turbine and the blast furnace or red switch occurs. Should take the following measures: appropriate to increase the amount of coal to improve the furnace heat load; adjust the secondary air ratio, increase the amount of lower secondary air; improve wind, air pressure, increased gas velocity; hydrophobic and full of air and exhaust mother pipe in front of the main steam isolation all hydrophobic.

Chemical prevent high temperature corrosion of condensing technology domestic boiler guide waterwall boiler chemical improvements to prevent high temperature corrosion improvements waterwall 1, using an anti-art windshear main principle is offset by a spray angle of air flow injection port, and the original jet forming a motion , the opposite direction of rotation, in tangentially running smaller diameter, due to the opposite running direction of the initial movement of the main gas flow direction of the gas flow in the furnace after the anti-wind shear, the pulverized coal injected hindered high-temperature air upstream of the primary air flow and the time, the pulverized coal injection speed is reduced rapidly, enhancing coal dead time in high temperature zone, to enhance the combustion efficiency of pulverized coal. By using an anti-wind shear can effectively prevent high temperature corrosion phenomena, and can enhance the ability to stabilize combustion in the boiler furnace, reduced coke boiler case, as shown in FIG. 2, using the technology of Side by side wind technology is mainly on the high temperature zone waterwall corrosion or high temperature corrosion installed upstream of the injection port area, and ejecting the air in the furnace boiler. Technology is mainly employed side air can be controlled in the high-temperature reducing gas corrosion area, enhanced oxygen content in a local range. 3, to improve the control operation to take excess air coefficient increases, a plurality of coal mills is not put into operation at the same time, reduce the coal particle size, increase the air preheater ash fouling preventing plugging of equipment and operation control systems such as high temperature measures to prevent High temperature corrosion phenomena.

Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, condensing technology domestic boiler guide flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.
