Why do the new boiler diesel burners need to cook? How to cook?

Before the new furnace is used, the newly installed hot water boiler diesel burner must be boiled to remove the rust and stains in the furnace bladder and pipes. Please follow the following methods: (1) The feed water of the thermal oil boiler diesel burner should meet the relevant regulations of gb1576-2001 'Industrial boiler diesel burner water quality'. (2) The thermal oil boiler diesel burner and its water treatment, sewage, fuel delivery, lighting and other systems have been installed, and the water pressure test is qualified. (3) Pressure gauges, thermometers and other thermoelectric instruments should be installed and tested. (4) Diesel burner pipes, flues and valves of heat-conducting oil boilers should be marked with medium flow direction, opening direction and opening height. After the inspection and trial operation of each part of the boiler diesel combustion engine, the boiler diesel combustion engine can be started after confirming the safe starting conditions of all components. 1. When the hot water boiler diesel burner is cooked, appropriate drugs should be added to the boiler diesel burner to make the boiler diesel burner water alkaline and remove oil, dirt and other dirt. 2. The above-mentioned drugs used in the boiler diesel burner should be mixed into a uniform solution with a concentration of 20%, and the solid drugs should not be directly added to the boiler diesel burner. 3. Close the pipe seat, hand hole and main outlet valve seat of each part, open the inspection hole, pour the prepared liquid medicine into the pot at one time, then close the inspection hole and open the exhaust valve; let the air in the furnace have An exit. 4. After clicking the burner power switch, click the start button, the power supply of the control system is connected, and the burner enters the working state. According to the action program of the program controller, the pressure in the pot should always be maintained. 5. After the water temperature of the boiler diesel burner gradually rises to 70°C, open the drain valve to release all sewage. The purpose of the boiler diesel burner is to add NaOH and Na3Po4.12H2O to the boiler diesel burner for chemical treatment, use a sealed boiler diesel burner to remove oil and rust in the boiler, and ensure that the boiler diesel burner is evenly heated and runs normally. The dosage added in the boiling furnace should meet the following requirements: calculate the drug with 100% purity. When there is no trisodium phosphate, sodium bicarbonate can be used instead, and its amount is 1.5 times that of trisodium phosphate. Sodium carbonate can be used alone in the cooking stove, and its dosage is 6Kg/m3 water. In addition, the end of the boiler diesel burner should maintain the pressure of the boiler diesel burner at about 75% of the working pressure. The boiling time is generally 2-3 days. During the boiling furnace, the boiler water test and analysis should be carried out regularly, and the boiler water sealing degree should not be low. Less than 45mol/L, otherwise it should be added. After the cooking furnace is completed, the sediment in the drum of the boiler's diesel burner should be cleaned, and the valve inside the pot in contact with the liquid should be cleaned to check whether there is any blockage. After cooking, please meet the following requirements: (1) The inner wall of the drum and the collection box should be free of grease. (2) After wiping the accessories, there should be no corrosion on the metal surface. (3) The work of the boiler diesel burner should be carried out at the same time in the later stage of the oven. The boiler diesel combustion engine does not meet the requirements of the gas hot water boiler diesel combustion engine manufacturer, which will deteriorate the circulating water quality, corrosion of pipe fittings, water collection tanks and other components, endanger the safe and economic operation of the gas hot water boiler diesel combustion engine, and affect the boiler diesel combustion engine Service life. After the boiler diesel burner is cooled, open the manhole and hand hole cover, clean the boiler diesel burner with clean water, and inspect it. If there is still grease, the boiler diesel burner should cook as described above until there is no grease in the hot water boiler diesel burner. Check before the start of the operation process 1. Whether the heating furnace and its surrounding environment are clean and free of debris, check whether the furnace body, burner, controller, fire hole and smoke (chimney) passage are normal; 2. Countercurrent process equipment and process, check expansion Whether the oil level of the water tank is higher than 1/4 to 1/2 level, whether the thermometer and pressure gauge are normal; 3. Connect the heating furnace control cabinet power supply, check whether the voltage is normal, check whether the indicator light and all display instruments are normal; 4. Adjust The main pressure reducing valve and the secondary pressure reducing valve control the pressure at 0.005mpa. Start 1. Start the heat transfer oil circulating pump (standby, according to the pump operation rules), and keep the pressure stable for about 0.5 hours after starting the pump; 2. Press the burner start button and observe whether the flame in the furnace is burning normally. If it does not ignite, please start the burner again after troubleshooting. Furnace operation 1, normal stop (1) Gradually reduce the temperature, turn off the burner, and stop burning; (2) When the hot oil temperature drops below 70°C, stop the operation of the hot oil circulating pump (see the operation rules of the water pump); ( 3) Turn off the main power and make a record of switching. 2. Emergency stop. If the furnace is shut down due to an emergency, the burner should be shut down quickly, and the burner should be moved along the burner reaming axis to form a natural ventilation state between the furnace and the chimney, accumulate heat and distribute it in the furnace, so that The heat transfer oil cools naturally to prevent overheating. !
