natural gas 1 ton per hour steam boiler

The inlet speed of gas-fired hot-water boiler before start-up should not be too fast, usually no less than 4 hours in winter, and 2-3 hours in other seasons, especially in the initial stage of water intake. The inlet temperature of a gas-fired hot water boiler is generally 50 °C, so the difference between the feed water temperature and the steam wall temperature in the drum is less than 40 °C. For gas-fired hot water boiler, the inlet water temperature can be equal to that of steam drum wall without complete cooling, otherwise the inlet water speed should be slowed down. When feed water enters the drum, it always first touches the lower part of the drum. If the difference between the feed water temperature and the drum wall temperature is too Large, the inlet speed is fast, and the upper and lower walls of the drum, the inner and outer walls will have a large expansion. Bad, on the drum caused a lot of additional stress, resulting in drum deformation, serious cracking. Due to the thickness and slow expansion of the drum wall, the tube wall connected to the drum wall is thinner and expands faster. If the inlet temperature of the gas-fired hot water boiler is too high or the inlet speed is too fast, the expansion will be uneven, the welded joint will appear cracks and the gas-fired hot water boiler will be damaged. The inner diameter of the decompression tube is usually φ 7~13mm (water and steam), and its length should not be too long (< 60m). Straightness of pressure pipe If the diameter is too small and the length is too long, it will affect the dynamic transmission of pressure measurement and increase the dynamic error. The inner diameter is too large to be easily maintained and installed. Pressure pipes should not be placed in the horizontal part to prevent the accumulation of bubbles (when measuring liquids) and water columns (when measuring gases). The pressure tap shall be perpendicular to the flow of the medium. Pressure faucet must not have chamfer, flange and burr. When measuring the hydraulic pressure of an electrically heated 1 ton per hour steam boiler, the pressure outlet should be removed from the lower part of the pipe to prevent the gas in the liquid from entering the pressure guide pipe; When measuring the gas pressure, remove the pressure splice from the upper part of the pipe to prevent dust and dust in the gas The droplets enter the ignition line. The installation site of the electric heating steam boiler pressure gauge (pressure transmitter) should meet the environmental conditions (temperature, humidity, vibration, etc.) used by the instrument, and should be easy to observe, repair and ensure safety. Insulation should be laid on pressure pipes in high temperature media to avoid burning during flushing. Pressure lines are equipped with needle valves (for cutting off pressure in the event of pressure line failures during operation), auxiliary needle valves (for use with instruments, stopping, replacement), condensing coils and elbows (isolation elastic elements from high-temperature media), Easy to install sealing gaskets) as well as sewage valves and sewers. For special pressure measurements, it's still pressing. Install discharge valve, isolation room and so on in the force pipe.

Commissioning of Boiler gas boiler commissioning must be carried out after the hydrostatic test. Before commissioning, should be a comprehensive inspection of each furnace parts, electronic control devices, wiring, etc. are normal, water supply, oil furnace if opened, electrical contacts are in the set position. 1, depending on the size of the fuel consumption, the initial damper, the hydraulic pressure. 2, the power is turned on, the power switch to open the cabinet, the water pump starts furnace, (if the pump is rotated into the anhydrous, pump purge valve is opened, the air exhaust pump). 3, control checks whether the normal water level electrode. 4, check the burner operation is normal. Starter burner starts combustion when the water level rose to a predetermined level, the start of combustion is normal to observe: Start no vibration noise, stable combustion, no smoke, orange yellow flame, burning bright clear. Otherwise, to make the appropriate adjustment (refer to burner instructions). Note: The oil pressure between 0.8 ~ 1.0Mpa, after a good tune, do not easily change, oil pressure is too high or too low have an effect on burner performance life. 5, check the pressure gauge pointer swing is smooth, with or without loosening stuck. 6, whether the discharge check valve is set at the set pressure steam: Pressure controller first maximum working pressure, a safety valve is adjusted to the set pressure higher than 0.05MPa, when the furnace pressure was raised to whether the exhaust pressure setting, if exhaust , pulling the safety valve a few times, and try again, if not enough to deal with safety valve to adjust. Pressure relief valve setting: boiler rated pressure + 0.03MPa. 7, check the electrical contacts of the operation: When the pressure is raised to the maximum working pressure (not exceed the rated working pressure), should stop burning, open the safety valve blowing off steam, the pressure to a minimum operating pressure (maximum operating pressure is generally lowest set to 0.10MPa), combustion burner should be restarted. Note: When the adjustment screw should slow, especially when the pointer approaches the end, otherwise, damage the screw off the wire.
