blown gas waste heat boiler in philippines

Fuel gas blown waste heat boiler in philippines high degree of automation, higher operating costs than coal, small footprint, requiring less operator; while the gas boiler environmental factor is very high, is the fuel of the future of major equipment recommended.

Gas-fired steam blown waste heat boiler in philippines safety valve from installation to use, it must remain vigilant safety valve is one of the most important components of the gas steam boilers, boiler probability of the risk occurring due to various incidents can effectively suppressed. This article focuses on the safety valve from installation to use several important considerations, we do not ignore the use of gas when it steam boiler. A Notes 1 safety valve, the safety valve should be mounted vertically in a high position in the pot business, set box. 2, between the safety valve and the drum or header, not equipped with access to the steam outlet pipe and the valve. 3, the lever-type safety valve should prevent movement of the self-apparatus and the weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly. 4, the rated steam pressure less than or equal to 3.82MPa gas steam boiler safety valve throat diameter of not less than 25mm; power greater than the rated steam pressure 3.82MPa boiler safety valve throat diameter not less than 20mm. 5, the safety valve and coal-fired steam boiler tubes, the cross-sectional area not less than the cross-sectional area of ​​the valve inlet. If several valves installed together with a short tube directly connected to the drum, the cross-sectional area of ​​the passage should not step short tube to 1.25 times the area of ​​all the exhaust valve. 6, the safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. 7, the safety valve exhaust pipe at the bottom should have received a place of safety posturing of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve. 8, rated evaporation to 0.5t h coal-fired steam boiler /, at least two safety valves installed; Rated evaporation 0.5t h less than or equal to electric boiler /, mounted on at least a safety valve. 9, separable economizer outlet, the steam superheater outlet valve must be installed.

Chemical prevent high temperature corrosion of blown waste heat boiler in philippines 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.

Before the end of December 2019, the new installed capacity of 340,000 kilowatts of new energy. Among them, the wind power installed capacity of 300,000 kilowatts; biomass 15,000 kilowatts; gas generating 25,000 kilowatts.
