The latest requirements for the design specifications for boiler diesel burner rooms in 2019

The installation of the thermal oil boiler diesel burner has certain requirements for the construction of the boiler diesel combustion engine room. 1. Requirements for the construction of boiler diesel combustion engine room 1) The boiler diesel combustion engine room must comply with the 'Regulations for the Supervision and Management of Energy-saving Technology for Boiler Diesel Combustion Engines' and the 'Design Specification for Industrial Boiler Diesel Engine Room Design'. 2) The diesel combustion engine room of the boiler should have adequate lighting, good ventilation, and necessary anti-freezing measures. The boiler diesel combustion engine room should be far away from schools, houses and densely populated places. 3) The location of the boiler diesel combustion engine room should be as close as possible to the thermal equipment to reduce the loss of the hot oil circulation pump head and the heat loss of the pipeline. 2. Layout requirements for heat carrier furnace equipment 1) The oil storage tank should be 1 meter lower than the lowest position of the heat carrier furnace and heating system in order to discharge the organic heat carrier in the boiler diesel burner and the system. The space between the oil storage tank and the heat carrier furnace shall not be less than 5 meters or be separated by partitions. The oil storage tank should be equipped with an exhaust pipe with a diameter larger than the expansion pipe. 2) The location of the expansion tank should be higher than other equipment and pipes in the system, and its bottom should be 1.5 meters higher than the highest liquid level of the system. If the organic heat carrier overflows and causes a fire, it must not be installed directly above any boiler diesel burner. 3) The drain pipes on the oil storage tank and expansion water tank should be connected to an outdoor safe place. Valves must not be installed on the discharge pipe to ensure that the oil storage tank and expansion tank are connected to the atmosphere to ensure normal pressure operation. 4) Due to thermal expansion at working temperature, the volume of the high-expansion water tank should be 1.3 times larger than the heat carrier furnace and all the organic heat carriers in the entire heating pipe network system. 5) The volume of the low storage tank should not be less than 1.2 times the total organic heat carrier in the heat carrier furnace. 6) A space of at least 0.5 meters should be maintained around the hot oil circulating pump to ensure the daily inspection, installation and maintenance needs. Specification for design of gas boiler diesel combustion engine room 1. The boiler diesel combustion engine room is suitable for independent buildings. When the boiler diesel engine room is connected to or installed in other buildings, it is forbidden to set up and place important departments (such as public bathrooms, classrooms, restaurants, etc.) Cinema auditoriums, conference rooms), waiting rooms, archives, shops, banks, waiting rooms) one floor, the next floor, glued to adjacent locations and on both sides of the main passage, evacuate, and should be set on the first floor or The first floor or basement outdoor wall area. 2. The boiler diesel combustion engine room is not suitable for residential buildings. The entrance and exit of the boiler diesel combustion engine room must meet the following requirements: the entrance and exit shall not be less than 2, but for the independent boiler diesel combustion engine room, the total length of the front passage is less than 12m, and the total construction area is less than 200 square meters; the non-independent boiler diesel combustion engine room, Its personnel entrances and exits must directly enter the outdoors. 3. When the boiler diesel combustion engine room is arranged in multiple layers, each floor should have no less than 2 entrances and exits. There should be a safety staircase leading directly to the ground. 4. The door leading to the outside of the diesel combustion engine room of the boiler should be opened outward, and the door of the working or living room of the diesel combustion engine room of the boiler should lead to the diesel combustion engine room of the boiler. According to the GB50041 design specification of boiler diesel combustion engine room, attention should be paid to its application range: steam boiler diesel combustion engine room with water as the medium, single boiler diesel combustion engine rated evaporation capacity is 1~75t/h, rated outlet steam pressure is 0.10~3.82 mpa (gauge pressure). 5. The exterior wall of the boiler diesel combustion engine room, floor or roof shall have corresponding explosion-proof measures, and there shall be a pressure relief area equivalent to 10% of the floor area of ​​the boiler diesel combustion engine room, and the pressure relief direction shall not face the place where people gather. Rooms and pedestrian passages, pressure relief should not be adjacent to these places. 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. Matters needing attention During the inspection, you should pay attention to check whether there is any leakage around the diesel burner of the conductive oil boiler. There should be sufficient petroleum and electrical fire fighting equipment nearby. Water should not be used as an extinguishing agent. !
