How to set up the piping system of the heat-conducting oil boiler diesel burner

The pipe diameter of the thermal oil boiler diesel burner should be reasonably determined according to the pipe length, the pump head and the heat used . 1. Seamless steel pipe (GB/T8163) must be used in the furnace of the heat transfer oil pipe. Welded or flanged valves and fittings must be at least 1.6mpa. Cast iron and non-ferrous metals are not allowed. 2. The diameter of the expansion pipe connected to the heat transfer oil boiler diesel burner and the upper fuel tank oil and gas separator should not be less than the value specified by the safety technical supervision of the organic heat carrier furnace. The bending angle of the pipe should not be less than 120 degrees. It is strictly forbidden to install valves and insulation in the pipeline. Floor. 3. The diameter of the overflow pipe of the upper water tank shall not be less than the diameter of the expansion pipe. 4. The diameter of the exhaust pipe of the lower groove of the heat-conducting oil furnace light oil burner should be one level larger than the specified value of the expansion pipe. 5. The heat-conducting oil boiler diesel burner should be equipped with exhaust valves and exhaust valves at the highest and lowest parts of the system. 6. Two valves must be installed in order to connect with the circulation system in a low tank. 7. The installation slope of the pipeline is 2‰-3‰. 8. The installation of the pipe frame of the heat-conducting oil boiler diesel combustion engine should be reasonable, and the pipeline should take heat compensation measures. 9. The sealing material at the pipe joint should be metal wound graphite gasket or expanded composite graphite gasket. Operation process pre-start inspection 1. Check whether the boiler diesel burner and its surrounding environment are clean and free of debris, check whether the furnace body, burner, controller, fire hole, and smoke pipe are normal; 2. Reverse process equipment and process, check Whether the oil level of the expansion tank is higher than 1/4 to 1/2 level, and whether the thermometer and pressure gauge are normal; 3. Turn on the power supply of the heating furnace control cabinet, check whether the voltage is normal, check whether the indicator light and all display instruments are normal; 4 .Adjust the main gas pressure reducing valve and the secondary pressure reducing valve to control the pressure at 0.005mpa. Start 1. Start the heat transfer oil circulating pump (one for transportation and one for preparation, according to the pump operation rules), after starting the pump, it will circulate normally for about 0.5 hours to stabilize the pressure; 2. Press the burner start button and observe the furnace Whether the flame is burning normally. If ignition does not occur, please start the burner again after troubleshooting. Furnace operation 1. Normal shutdown (1) Gradually reduce the temperature, turn off the burner, and stop burning; (2) Wait for the temperature of the hot oil to drop below 70℃, and stop the operation of the hot oil circulation pump (refer to the pump operation procedure); (3) ) Turn off the main power and make a shift record. 2. In case of emergency shutdown, the burner should be quickly shut down and the burner should be removed along the hinge axis of the burner to form a natural ventilation state between the stove and the chimney so that the heat in the stove can be distributed to the heat transfer oil Natural cooling to prevent overheating. Matters needing attention When checking the circuit, please pay attention to check whether there is electricity leakage around the heat-conducting oil furnace and light oil burner. Sufficient oil-electric fire-fighting equipment should be equipped nearby. Do not use water as a fire extinguishing agent. Troubleshooting 1. The temperature of the outlet oil is too high. When the outlet oil temperature exceeds the outlet oil temperature by 20°C or more than 350°C, the computer will flicker over temperature, and the controlled equipment will be forcibly shut down. 2. The flue gas temperature is too high. When the flue gas temperature exceeds the set limit temperature of 300 ℃, the flue temperature is too high indicator will shut down the controlled equipment. 3. Low pressure difference When the oil pressure at the inlet and outlet of the boiler diesel burner is lower than the set pressure difference, the computer will indicate a fault and it will be forced to stop. Controlled equipment. 4. Overpressure When the oil pressure of the boiler diesel combustion engine is higher than the set high pressure point, the computer malfunctions and the controlled equipment is forcibly shut down. 5. Power prompt When the system grid voltage exceeds the normal working range (180v-260v), the screen fault prompt will not cause the equipment to interlock. !
