How to maintain the boiler during operation of the boiler during operation how to maintain water supply and water quality monitoring furnace boiler feed water and boiler water boiler maintenance ⑴ should be consistent with GB / T1576-2008 "industrial boiler water quality" standards. And regularly sampled for testing. The number and frequency of emissions is determined by laboratory personnel. Laboratory and sewage should be detailed records. ⑵ mechanical rotation monitoring for pumps, fans, pumps, etc. to be employed a method of three touch see two monitors. Abnormal phenomenon, that approach to take. If necessary, to shutdown maintenance, are not the effect. ⑶ daily oil tank oil level monitoring if no automatic control device, the oil level should be checked regularly and found that the oil level is too low, the use of two hours is not enough, please notify the staff in advance of the fuel injected new fuel. ⑷ soft water tanks commonly used to control the operating state of the automatic control device ⑸ To periodically check the water treatment apparatus to the ion exchanger is failed, or periodically backwashed. ⑹ monitor the exhaust gas temperature under normal circumstances, the new boiler is generally lower exhaust gas temperature, with the increase in run time will gradually increase. If it is found that the change is too large and exceeds 20 ℃ (algebraic difference), you should select the appropriate cleaning shutdown time. If this phenomenon occurs very frequently, it will have to check whether the normal combustion system. The oil pressure is too low, resulting in poor atomization low oil temperature, oil or wind than not, resulting in poor fuel air mixture so that the char combustion analysis hypoxia. Further, the dry back boiler, if the exhaust gas temperature increased abruptly, it is possible to return in a compartment between the second and third after the smoke box backhaul firewall leak smoke, shutdown would need repair.

Hot water boiler belongs to special equipment, and is also a kind of high temperature and high pressure thermal energy equipment. It is inevitable that some faults will occur in the process of operation, which are normal, but it is very likely that the explosion of 0.7mw-14mw hot water boiler will occur if it is not properly dealt with. Therefore, for equipment safety and personal safety, we must understand some prevention hot water boiler explosion common sense. In the design of hot water boiler, thermal calculation and strength calculation should be carried out strictly according to the requirement, the structure layout should be reasonable, and the material selection should be qualified. In order to ensure the boiler quality conforms to the drawing, the boiler should be constructed according to the drawing. The degree of delimitation. Boiler safety accessories should be complete, agile and reliable, and on-time maintenance, frequent inspection, failure of accessories should be replaced in a timely manner. Repair and repair the boiler inside and outside the boiler according to the schedule, repair and reform the existing problems in time to ensure the quality of inspection. 2. Fuel oil and gas-fired hot water boiler explosion accident in furnace to prevent explosion of hot water boiler should be carefully checked before the point of the hot water boiler, whether the oil path is tight (leakage), the pressure is normal or not, and the newly installed and modified oil and gas pipelines must be blown clean. Check whether the blower has been ventilated for 5 minutes before ignition, and analyze the reasons after ignition failure, and then follow the ignition procedure to penetrate the air. Ignite. For boilers that have not been certified for boiler use and annual inspection, the grater has the right to refuse to light the furnace. The enterprise should lay down the experienced stoves who have rich experience in the operation of the furnace. The staff of the furnace should step up the tour inspection, deal with the problems in time, prevent the flameout, and stop the fuel as soon as it is found out. The boiler shall be equipped with automatic protection devices, including automatic ignition, flameout protection, automatic combustion regulation and necessary interlocking alarm protection devices.
Gas-fired steam boilers are a very wide range of special equipments, widely used in food, chemical, paper, textile, construction and other industries. In the process of loading and installing a gas steam boiler, some problems must be paid attention, otherwise it may cause a certain degree of economic loss.
1. Pay attention to the following matters during the loading and unloading and handling of gas-fired boilers: the lifting capacity of the lifting equipment should match the weight of the lifting boiler. The lifting lug on the boiler with the lifting lugs that cannot be used for lifting can not be used for lifting. The length of the steel cord should be reasonably selected to avoid the scratching of the furnace due to the improper length of the steel cord. The boiler must be protected from any damage during handling and handling.
2. Reserves for maintenance space When installing boilers, ensure that there is sufficient maintenance space around the boiler.
3. Setting and precautions for the base and base of the gas steam boiler The boiler body must be installed on the basis of 100-150mm above the floor of the boiler room. It must be confirmed with the technical personnel of the boiler manufacturing company in advance and constructed according to the basic drawings. The anchor bolts must be reserved on the foundation. The foundation shall be capable of withstanding the maximum weight of the boiler and the amount of water it holds. When installing the base, you must first position it. After positioning, adjust to the same length of the two diagonals of the base, and then tighten all the fixing bolts. The installation of the base is carried out with reference to the reference line.
4, general precautions Be careful not to tilt and impact the boiler and accessories too much. No combustibles can be placed around the boiler. Do not use oil and water to smother the boiler. The boiler should normally be installed in a separate boiler room. The new gas-fired boiler room should not be connected to the house. The boiler room shall not be connected to Class A, Class B and Category C fire hazard rooms using flammable liquids. If connected to other production plants, the application firewall is separated.
5. The fire resistance grade and fire protection requirements of the boiler house building shall comply with the requirements of the Code for Fire Protection of Building Design and the Code for Fire Protection Design of High-rise Civil Buildings. The ground of the gas steam boiler room should be flat, non-flammable, no water accumulation, and the foundation load should meet the requirements. The power supply voltage of the gas steam boiler room should be stable to avoid causing the electrical components to burn out. If the voltage is unstable, it is recommended to install a voltage regulator. Ventilation equipment should be installed in the boiler room, and the boiler should be kept at room temperature below 50 °.
