(L) Rated evaporation is greater than 0.5t / h of energy saving boiler, installed at least two safety valves; rated evaporation that is less than or 0.5t / h steam boiler boiler GB arts conducting oil furnace, at least install a security valve. Separable economizer outlet of the steam superheater safety valve installed at the outlet are required. (2) safety valve should be installed vertically in the highest position the boiler drum, set box. Between the valve and the drum or header, not equipped with access to the outlet pipe and valves energy saving boiler. (3) there must be a safety valve to prevent the hammer leveraged their own mobile devices and limit leverage deviant guides, spring-loaded safety valve must be promoted to handle and prevent casual twist adjustment screw devices. } (4) For the rated steam pressure that is less than or 3.82MPa boiler safety valve throat diameter of not less than 25mm; For the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20mm. (5) connecting tube boiler environmental Arts conducting oil furnace and boiler safety valve, energy saving boiler its cross-sectional area of ??not less than the cross-sectional area of ??the inlet valve. If several valves installed together on a short tube directly connected with the drum, channel cross-sectional area of ??not less than short tube all the exhaust valve area 1.25 times. (6) general safety valve should be installed in the exhaust pipe, exhaust pipe runs should be a safe place, and there is sufficient cross-sectional area, to ensure the smooth flow of the exhaust. Safety valve should be fitted with an exhaust pipe at the bottom of the drainage pipe connected to a safe place, in the exhaust pipe and do not allow the installation of drainage pipe valve. Oil furnace (also known as thermal oil heater) is to be the electric heater directly into the organic vehicle (HTF) directly heated by the circulation pump, forcing liquid phase heat transfer oil circulation, the heat transfer to the use of one or more kinds of heating equipment, heating equipment after uninstalling and re-circulating pump through, back to the heater, and then absorb heat, heat transfer equipment to use, so the cycle oil furnace, continuous heat transfer, so that the heated object temperature rise high, reaching the heating process requirements. Thermal oil heater with digital temperature controller, with over-temperature alarm, low oil level alarm, super-pressure alarm function, which is the chemical, petroleum, machinery, printing and dyeing, food, shipbuilding, textiles, film and other industries of one energy efficient heating equipment.
