Industrial Gas Oil Dual Fuel 1 05 MW Pressure Hot Water Boiler

Industrial Gas Oil Dual Fuel 1 05 MW Pressure Hot Water Boiler

Use boiler fireman in charge of daily operations would be required to learn knowledge about the use of the burner. Fireman personnel to achieve the "three to understand the four" standard that is to understand the operating principles, understand the rules, understand safety regulations; boiler operation will be, will be troubleshooting, maintenance will be simple, routine maintenance will be. When the burner has perceived findings among the working process should be shut down and notify maintenance personnel, if the need to disassemble the combustor for inspection or maintenance work, must first turn off the power and fuel. 1. boiler door lock, should ensure that the door to shake, and safe and reliable. 2. Prohibit the use of paper and garbage incineration boilers. 3. The protection system of boilers and burners comprising: explosion vent (boiler), heating system pressure protection, water protection, pressure protection, high pressure protection, low pressure protection, flame monitoring protection. When the burner practice, various protection signals are sent to the program controller, the respective program controller protection signal has been received, the protection signal only when all are normal, to start the burner. 4. The tightness of the gas line during the installation process has been checked. In general, not detached. It takes disassembly, after re-connecting line should be checked for air tightness. The gas supply pressure valve can not exceed the maximum allowable pressure in the combustor is indicated on the nameplate. When abnormal supply pressure, the burner should be closed. 6. When the filter is dirty gas pipe line, a valve should be closed pipeline cleaning (or replace) the filter gas pipe. 7. The front portion of the photosensitive surface of the photoelectric sensing should be kept clean, periodically remove the wipe. However, please note that when a sense of photoelectric eyes back into the electric eye sockets, electric eyes photosensitive part should be toward the front. 8. The temperature in the vicinity of the burner is not too high, or else the burner portion of the assembly constituted damage, especially in the control box. 9. near the burner should be kept clean, can not put their things, so as not to be drawn into the burner, resulting in losses. 10 is too high, too low or unstable portion of the assembly of a voltage configuration would damage the burner, may also affect the normal operation of the burner. 11. The burner should avoid being splashed water. Should maintain indoor dry, ventilated. 12. The flame burner requires a volume of air when burned, please keep in circulation boiler room air. 13. If the burner for an ignition fails to restart, you must wait a period of about about 10 minutes, until the combustible gas furnace burner cleared before restarting. After three consecutive failures, not in the start-up burner, shall promptly notify the professionals to repair.

Multi-fuel steam boiler protection water protection Fuel steam boiler: boiler water level gauge plate supporting one to two, should always be compared with each other, findings indicate inconsistency shall be corrected immediately. Class water level should be flushed, to determine their true level. While the water level comes electrode rod can accurately capture level signal to an alarm or a pump control. A steam pressure protection, the pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switches, automatic control chain protection or other control lines. Using pressure controllers and electrical contacts, the vapor pressure can overpressure alarm; single adjustable pressure controller or dual fire burning fire the actual operating pressure. 2, the safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. Flame protection: imported burner having a flame protection device, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged of residual internal combustible gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. Self-locking power failure protection: Under the emergency power supply is interrupted, the boiler shutdown immediately self-locking, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition.

In mid-June this year, Hebei Province issued a notice regarding the development of gas-fired boiler nitrogen oxides (referred to as NOx) governance, in order to further deepen the boiler pollution control, reduction of nitrogen oxide emissions, improving air quality, will gradually nitrogen oxides exceeded boiler discharged for investigation and control work, high nitrogen oxide emissions from the original (150mg / Nm3 or above) is reduced to 30mg / Nm3. City, Hebei Province is located in the Yili Dairy Co., Ltd. to respond positively to governance EPA gas boiler NOx reduction, and led the way, three of the company's existing 15 steam tons / hour (t / h) gas steam boilers for low-nitrogen emissions transformation.

Daily maintenance of gas-fired boilerDuring operation, the gas-fired boiler should pay attention to the following points: (1) the gas-fired boiler does not allow positive pressure combustion or smoke injection in the furnace because it is easy to burn out the coal hole cover. (2) the bottom floor plane of the gas-fired boiler shall not be watered up in order to prevent damp corrosion. The gas-fired boiler shall be inspected every 2 weeks and every 3 months after the operation of the gas-fired boiler. (1) the gas-fired boiler shall be inspected and repaired in an all-round way after the operation of the gas-fired boiler every 3 months. (1) the gas-fired boiler shall be inspected inside and outside the boiler. If the pressed part of the weld, steel plate inside and outside corrosion phenomenon, if found in serious defects should be repaired in time, if the defects are not serious, the next time the furnace shut down repair, if found When suspicious, but does not affect the safety of production, records shall be made for future reference. (2) after inspection, boiler primer may be applied on the surface to prevent corrosion. 4. Gas-fired boilers and boiler base shall be painted at least once a year. 5, There are dry and wet methods for the maintenance of gas-fired boilers: dry method and wet method. Dry maintenance method should be adopted when the boiler is shut down for more than one month. (1) dry maintenance method: after boiler shut-down, the boiler can remove the water from the furnace, and the method of dry maintenance shall be adopted under one month. (1) dry maintenance method: after the boiler has shut down the furnace, Thoroughly remove the internal dirt, rinse clean, dry the furnace with a slight fire (be careful not to fire), and then apply a 10-30 mm diameter lump of quicklime. The plates are arranged and placed in the pan, without contact with the metal. The weight of quicklime is calculated at the volume of 8 kilograms per cubic metre of the drum, and then all manholes, hand-holes, pipe valves are closed and checked every three months. If the quicklime is broken, it needs to be replaced immediately. When the boiler is re-running, the quick lime and the tray shall be removed. (2) Wet maintenance method: after the boiler has stopped the furnace, the boiler shall discharge the furnace water, thoroughly remove the internal dirt, rinse it clean, and reinject the treated water until it is fully filled. Heat the furnace water to 100 ℃, let the gas from the water out of the furnace, and then close all the valves, where the climate is cold, do not adopt moisturizing method, so as to avoid the furnace water Icing damaged the boiler.
