During the ignition process of a gas fired boiler, the fuel pressure, fuel temperature, atomizing steam pressure, atomizing steam temperature and other parameters must meet the requirements of the operating regulations. Observe on-site that the oil gun is on fire and the fire detection returns to normal. It is forbidden to short-circuit the fire detection signal forcibly The oil gun is running. When the flow rate of a single oil gun is greater than 0.65kg/s, the operation of this oil gun should be immediately exited. During the operation of a 2.5 ton gas fired boiler, the “black furnace” and “main fuel loss protection” must be put into operation in accordance with the requirements of the operating regulations.
When this series of boiler products are in operation when the protection device itself fails and needs to be temporarily withdrawn from operation, it must be approved by the manager in charge or chief engineer. When the “black furnace” and “main fuel loss protection” devices are out of operation, the attendant should focus on monitoring the furnace negative pressure, oxygen content, main steam temperature, main steam pressure and other parameters, and monitor the fire situation of the furnace through the industrial TV. If found Fire in the furnace and stop the furnace urgently.
After the gas-fired steam boiler is ignited, pay attention to the rise of the furnace smoke temperature, main steam temperature, and main steam pressure. If the smoke temperature rise rate is obviously slow or the smoke temperature does not rise after the boiler is ignited, go to the spot to check the ignition of the oil gun immediately. It was found that the fuel oil did not catch fire after entering the furnace, so the furnace was stopped urgently, and the furnace was ventilated and purged again. It is strictly forbidden to put the oil gun into operation without boiler ventilation. After the 2.5 ton gas fired boiler is extinguished, it is strictly forbidden to put the oil gun into operation without boiler ventilation. In normal operation, the fuel system and fuel gun are in good standby condition, and if the boiler is found to be unstable, the fuel will be added immediately to support combustion.
After the WNS series gas boiler is tripped or shut down normally, the furnace shall be ventilated and purged immediately to remove the unburned coal and combustible gas in the furnace in time. And close the manual main door of boiler supply and return in time to prevent the oil gun from leaking fuel into the furnace. Confirm that the gas boiler has extinguished, and when the MFT is not activated, stop the furnace in an emergency, and check that the two primary fans, 4 coal mills, and 16 oil guns have stopped running. The product is rigorously adjusted by professionals before use. The user only needs to connect the power and air source, and press the start button to enter the automatic operation state of the boiler without complicated installation.
The front and rear smoke boxes of the 2.5 ton gas fired boileradopt an integral structure, and the smoke box has a side-by-side smoke box door. The WNS series steam boiler has good integrity, beautiful appearance, and generous appearance. It is easy to open during maintenance and has good airtightness. The boiler uses aluminum silicate fiberboard as the thermal insulation material, which has good thermal insulation performance, light weight, and convenient transportation and installation. The upper part of the boiler is equipped with a manhole device, and the lower part is equipped with an inspection device, which is convenient for users to maintain and maintain.
