Heat conduction oil boiler diesel burner safety valve

The daily use of hot oil stoves in the history of industrial equipment is the most widely used. One of them is a pressure vessel, and its use is related to people To ensure the safety of life and property, the last-line fuse and heat-conducting oil burner light oil burner = safety valve. The pressure reducing valve plays an important role. The safety valve of heat conducting oil burner light oil burner and pressure reducing valve equipment must comply with the following technical requirements :1. For the additional steam emission of the light oil burner of the heat-conducting oil furnace greater than 0.5t/h, at least two safety valves are required: for the boiler diesel burner with the additional evaporation less than or equal to 0.5t/h, install at least one safety valve . The safety valve should be installed at the outlet of the separable economizer and the outlet of the steam superheater. 2. For boiler diesel burners with steam pressure less than or equal to 3.82mpa, the throat diameter of the safety valve should not be less than 25mm: For boiler diesel burners with additional steam pressure greater than 3.82mpa, the throat diameter of the safety valve should not be less than 20 mm. 3. The lever safety valve should be equipped with equipment to prevent the DSF's own weight from moving and a guide frame to limit the lever from derailing, and the DF spring safety valve should be equipped with a device to lift the handle to avoid any adjustment of the screw. 4. The safety valve should be equipped with an exhaust steam pipe. The exhaust pipe should directly reach the safe position and have a cross-sectional area conforming to DF to ensure smooth exhaust. The bottom of the safety valve exhaust pipe should be equipped with a drain pipe connected to a safe place. On-off valves should not be installed on the exhaust pipe and drain pipe. 5. After the safety valve and the boiler diesel burner are received, their cross-sectional area should not be less than the cross-sectional area of ​​the safety valve inlet. If some safety valves are installed together in a short pipe directly connected to the tank pipe, the entry cross-sectional area of ​​the short pipe should not be 1.25 times the exhaust steam area of ​​all safety valves. 6. The safety valve must be located between the tank and the collection box Highest position. DF should not install outlet pipes and steam valves between the safety valve and the boiler diesel combustion barrel or header. The safety valve of the heat-conducting oil burner and the light oil burner must be manually or automatically discharge tested regularly. Due to the adhesion of the valve body and the valve disc, regular testing can avoid adhesion and check whether the opening pressure of the safety valve is accurate and meets the requirements. The safety valve should be set as follows: the liquid phase boiler diesel burner and the system safety valve should be installed between the inlet and outlet stop valves of the boiler diesel burner. When the liquid phase boiler diesel burner is connected to the expansion tank and there is no valve on the connecting pipeline between the two, the boiler diesel burner body may not be equipped with a safety valve. Since the inlet and outlet of the boiler diesel burner are equipped with shut-off valves, when the connection between the boiler diesel burner and the system is cut off, since the boiler diesel burner itself is the heat source of the system, the heat transfer oil in the boiler diesel burner may be Continue to heat, leading to the risk of pressure rise, so the liquid boiler diesel burner must be installed with a safety valve. The safety valve should be installed on a closed expansion tank, and the inert gas and liquid are sealed in the liquid system. Gas-phase boiler diesel burners and system natural circulation systems should be equipped with at least two safety valves, one installed above the gas-phase space of the boiler diesel burner, and the other installed on the heating equipment or gas supply main pipe above the system. The safety valve should be installed on the flash tank and the condensing tank of the liquid phase forced circulation throttling and pressure reduction evaporation system. Two safety valves should be installed in flash tanks with rated heating power greater than 1.4MW. How much do you know about the two types of gas heat conduction oil burner light oil burners? 1. Vertical oil (gas) heat conduction furnace Vertical gas heat conduction oil furnace light oil burner uses electricity as the heat source and heat transfer oil as the heat carrier, and transfers the heat to the high-efficiency energy-saving heating equipment through the forced circulation of the heat pump. The equipment has compact structure, small size, light weight, convenient installation and operation, fast heating, no environmental pollution, automatic temperature control by computer, and higher working temperature can be obtained under lower working pressure. The computer automatically controls the light oil burner of the vertical gas-fired heat-conducting oil furnace, which operates stably at low pressure (≤0.4MPa), and the thermal efficiency can reach more than 90%. It is widely used in petrochemical industry, grease materials, building materials industry, textile printing and dyeing, food, plastics, rubber, pharmacy and other industries. It is a new type of ideal heating equipment. 2. Horizontal oil (gas) heat conduction furnace This product is diesel, natural gas, city gas fuel, the burner flame volume and heat exchange surface area are balanced to achieve the best temperature of the flue gas outlet exhaust pipe, super thick insulation layer, In order to achieve the minimum heat dissipation of the boiler diesel burner. All types of boiler diesel burners are assembled boiler diesel burners. The installation of boiler diesel burners only needs to connect system equipment and pipelines. The design of integrated boiler diesel burner makes installation convenient and quick. The boiler diesel combustion engine adopts intelligent control, which makes the operation of the boiler diesel combustion engine particularly convenient and simple. The controller is displayed on the simulation screen and is centrally controlled by the central processor. It has automatic ignition and shutdown program control, automatic combustion control, automatic switching and control of circulating pumps, automatic fault handling and alarm functions. !
