non ferrous metallurgy boiler in portugal

On the protection of Henan gas non ferrous metallurgy boiler in portugal - safety valve (B) 1. Henan gas boiler safety valve must have the following means: ⑴ spring safety valve must lift handle means and preventing movement of the adjustment screw is screwed lightly. ⑵ lever-type safety valve should prevent movement of the self-apparatus and the weight beyond the limitation of the lever guide frame. Means ⑶ weight plate from flying off the safety valve should prevent static weight. 2. For rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20mm. Several valves as mounted on a short tube directly connected with the drum, the passage sectional area of ​​the short tube is not less than 1.25 times the amount of all the area of ​​the exhaust valve. 3. Valve should normally be installed exhaust pipe, exhaust pipe should be as straight outside, and there is sufficient cross-sectional area to ensure smooth exhaust. Exhaust valve to the bottom of the tube should be fitted with a safe place of drainage pipe. On the exhaust pipe and drainage pipe not allow the installation of the valve. 4. Henan gas boiler valve seat throat diameter of not less than 25mm. Bleed tube valve should be installed in the drain pipe does not allow the valve means. Discharge pipe should be through a safe place, and there is sufficient cross-sectional area and freezing measures to ensure the smooth flow of exhaust. 5. Henan and safety valve for the gas boiler maintenance after a new installation, should check the safety valve open start pressure, pressure from the seat and the back seat pressure. Safety valve reseating pressure is usually the beginning of the start pressure 4 to 7%, the maximum does not exceed 10%. When the pressure is less than the beginning of Kai 0.30MPa, back seat a maximum differential pressure of 0.03MPa. The course of the general safety valve should be checked every year. After checking the safety valve, which began Kai pressure, pressure from the seat, back seat pressure calibration results should be recorded in boiler technology files. After the safety valve by check, should be locked or seal, is strictly prohibited heavy object, move the hammer, the spool stuck any other means to increase the pressure relief valve or safety valve open start failure. Henan gas boiler in operation, the safety valve is strictly prohibited splitting. 6. To prevent adhesions safety valve plug and seat, should regularly do manual or automatic safety valve exhaust, turn on the water test.

Combustion boiler using conventional techniques, from the media into the door hole, in the upper combustion grate, the flue gas was washed repeatedly laterally staggered in the cross-pipe furnace, in the flue gas containing fine dust particles and carbon black during the rise , multilayered tube is blocked, reducing the speed of movement, again falls on the combustion grate, burn the fumes into the atmosphere through the chimney.

What are the advantages of horizontal steam non ferrous metallurgy boiler in portugal? Selection of new refractory materials, without preheating load, high thermal efficiency, pressure stability, high-quality steam can be generated in a short time. Low combustion noise, low fuel consumption, low smoke emission, non-polluting, burning completely. Thus saving fuel costs and improve the economy, environmentally friendly energy-saving products. Sophisticated appearance: due to the continuous innovation of products and enhanced usability improvements, a clean, compact, vertical compact, especially small volume without foundation, easy installation, good looks, soft colors, harmony with the environment, artistic sense. Safe and reliable: automatic microcomputer control system, automatic boiler control, full function, you can set the exact time, start time, stop time, also has a self-diagnostic function, the boiler running them once the abnormal phenomenon, automatic interruption of water supply and combustion, concurrent sound and light alarm, safe, reliable, easy to operate. Durable: detailed design, strict selection, elaborate use of high technology, has the best corrosion resistance, durability and ruggedness [2]. Editing features: 1, water capacity, high thermal efficiency, steam production fast enough steam, long life ,, the deployment of quality brand-name burner and pressurized feed water pump, combustion, timely water supply, low noise. 2, having a self diagnosis function matching controller computer, running abnormal automatic shutdown and alarm and fault code indicating easy, maintenance. 3, complete protection, high temperature burner purging means may be provided, safe and reliable. High-relief valve assembly, a pressure regulator, thermal protection and low water multiple protection devices to ensure safe operation of the boiler. 4, compact, small footprint, elegant, bright color. 5, small crossflow 30-300kg / h with vertical double return, 500-1000kg / h Vertical three return. 6, energy efficient: Optimization of the furnace structure, a large heating area, in particular a high efficiency boiler heat Three-pass, gas production, long life. Matching high-quality brand-name burner and pressurized feed water pump, combustion, pollution-free, timely water supply, low noise [2].
