2019 hot style oil hot water boiler for hotel
What impact have fuel moisture steam boiler? Most of the aqueous fuel when coal or heavy oil with steam atomization of entrained moisture in an amount not more than 5%, no effect on the coil and the inner shell boiler, the boiler because their materials are steel, steel are mainly: 20g, 16Mng, 15CrMoVg, 19Mng, 22Mng, with a strong antioxidant, water resistance. With more moisture, combustion performance worse, if the moisture up to 40% burn will be extinguished.
Boiler and burner What is the difference? Simply put by the boiler and boiler furnace consisting Pot is the place to absorb heat, increasing the temperature is generally endothermic water, or water absorbs heat of vaporization of components, mainly heating water wall, etc. surface composition, and the fuel is coal furnace, where the heat released by burning oil, material, and other components mainly furnace while the burner is to provide a combustion apparatus of the release of energy, the material is spray combustion, combustion air.
Boiler equipment belongs to special, complicated structure design, operating environment is more severe, during use, is often influenced by temperature and pressure stresses and alternating. If long-term use down, inspection and maintenance neglect boilers, boiler operation will likely cause reduced efficiency and security risks. Once accidents, often fatal. But many companies and personal security awareness is not strong, it is still a long time to run the boiler inspection, inability to control the operation of the law of the boiler, there is a big security risk.
Recently, Gaoyou City, Jiangsu Province for coal-fired boilers Market Authority has embarked on a comprehensive inspection operations, according to "comprehensive coverage, thorough investigation, replicability, results-oriented" principle, the use of coal-fired boiler business diagnostic investigation, and effectively eliminate security risks.
City Supervisor Bureau focus on verification of the actual use of coal-fired boiler units, using the address, use, heating, technical parameters, test status, filing one by one, do on-site inspection records strict accordance with relevant provisions, retained image data. To phase out coal-fired boilers to be found in the inspection, and urge the relevant units to implement the safety responsibility, and return in time for retirement procedures using the registration certificate. So far, the council has issued eight safety supervision instructions to complete the verification of the use of 14 units of 45 coal-fired boilers and filing, of which three units have been deregistered 15 piece of equipment.
Matters needing attention in loading and installation of Gas-fired Steam Boiler
Gas-fired steam boilers are a very wide range of special equipment, usually built in boiler rooms. However, in the process of loading and installation, some problems must be paid attention to, 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.
