Matters needing attention in installation and Adjustment of Gas-fired Hot Heating Water Boiler
The installation of water supply line requires that the highest water level of the reserve pool is not strictly required. The surface water tank should be connected to the high water tank from the surface reservoir and the surface pool should keep the water clean. A steel wire filter shall be installed at the outlet of the pool (that is, the inlet of the recharge line).
When the return pipe is installed, the straight section of the outlet section of the return pipe shall be more than 0.5 meters, the bending radius shall be 4 times the diameter of the pipe, and an automatic discharge valve shall be installed at the highest point of the pipeline to prevent the circulation of steam in the pipeline. At the same time, the highest water level of the reserve pool for reliable insulation is generally required to be below the boiler level line as far as possible, so as not to drain a large amount of water when the boiler is shut down and the feed water flows into the boiler next time it starts. A steel wire filter shall be installed at the outlet of the pool (that is, the inlet of the water supply line).
3. Requirements for installation of oil supply lines 1. Boiler burners are retained; oil intake and oil intake; As long as connecting the oil supply pipe and the return oil pipe in the gas-fired hot heating water boiler room, 2 the arrangement of the boiler oil system between the special fuel tank and the inlet of the burner pump can be found in the operation instructions of the burners.
4, the chimney installation requires the chimney to be straight, its horizontal lead-out length should not be too long, generally less than 5 meters, chimney height should conform to the relevant national standards. Chimney with rain cap, chimney weight should not fall directly on the boiler main chimney pipe.
5, boiler hydraulic test gas-fired hot heating water boiler body and main pipe installation should be done after the hydraulic test. The internal inspection of the gas-fired hot heating water boiler should be carried out before the water pressure test. When the hydraulic test pressure is for the MPa, boiler, the water pressure should rise and down slowly. When the water pressure rises to 0.1MPa, the pressure rise shall be suspended, and the leakage or abnormal phenomena shall be checked. Then rise to the test pressure 0.2MPa for inspection, the pressure does not change during the inspection. The hydraulic test should be carried out when the ambient air temperature is higher than 5 ℃, and when the temperature is lower than 5 ℃, there must be anti-freezing measures. The water used in the hydraulic test is generally 20 ℃ 70 ℃. The requirement of fuel oil is light oil. Or natural gas (China), ordinary fuel oil heated to 100 ℃, its viscosity below 30E can be applied. Low calorific value of oil Qbw=10200Kcal/Kg viscosity is below 200E at 50 ℃, heating value of natural gas below 50E at 80 ℃ Qbw=8550Kcal/Kg calorific value of liquefied edible oil and gas Qbw=22000Kcal/Kg7, Check before starting work 1 to check if the line voltage meets the requirements, the various switch positions are normal; (2) whether the operation of water pump, burner and various auxiliary machines is normal or not; (3) except the main steam valve, Barometer cock, water level cock, air valve, other valves are closed. 4 check oil depot for adequate oil and pump, oil pump steering.
CWNS full-automatic gas-fired hot heating water boiler is a fast-mounted horizontal internal combustion three-way fire pipe structure. The second and third round-trip smoke pipes were washed by high-temperature flue gas, and then discharged into the atmosphere through the chimney from the rear chamber. Gas-fired hot water boiler is equipped with world famous burners, which adopts advanced technologies such as automatic proportional adjustment of combustion, automatic regulation of feed water, program start-up and stop, automatic operation, and has automatic protection functions such as running water temperature control, overheating, overpressure quenching and so on. The boiler has the characteristics of compact structure, safe and reliable, simple operation, quick installation, less pollution, low noise and high efficiency. It is widely used in enterprises. Pavilions, hospitals, office buildings, civil buildings and other facilities, industrial steam and living and heating. Second, the installation requires this type of boiler to be installed quickly, which is very simple to install. The boiler does not need special ground foundation, but only needs the ground with enough bearing capacity.
