Select the first wns series fired steam boiler to know what parameters? Steam boilers have the following main parameters: 1, Rated evaporation Rated evaporation is power steam boiler, steam boiler is the most important parameter, usually expressed in tons evaporation, that is, we usually say how many tons of boiler. 2, rated steam pressure rated steam pressure means that the steam pressure generated in the steam boiler, generally expressed in MPa or kg. 1MPa is 10 kg, like laundry, all hospitals, factories and the like conventional steam occasions the general use of low-pressure steam 1.0MPa or less. Only when using steam as a power to require the use of high-pressure steam. 3, where the steam temperature of said steam temperature, refers to the temperature of saturated steam. Saturated steam pressure and steam temperature are corresponding. Temperature of saturated steam at a pressure of 1MPa 184 ℃. 4, gas / oil / gas consumption fuel consumption is an important indicator of concern when choosing a steam boiler, which is directly related to the use of the running cost of the boiler. In the operation of the boiler, the fuel cost is very impressive, if just considering the purchase cost of buying a cheap but high energy boiler, which led to the late high operating costs, certain that it will be wasted. 5, the thermal efficiency of fuel consumption with the boiler thermal efficiency of boilers is inversely proportional. The higher thermal efficiency, lower fuel consumption of the boiler. Boiler thermal efficiency expressed as a percentage, the value is a more intuitive. 6, the boiler operating weight, size or location in the election of the steam boiler, it should find the place whether the load per unit area can withstand the weight of the steam boiler, and if there is enough space to place the steam boiler maintenance and reserve space.
Coal-fired boiler to carry out a comprehensive investigation and remediation work, Luohe City, Henan Province, Li Jizhen provincial, city and town each environmental supervision departments centralized call the relevant personnel, three-pronged approach to work.
First, a comprehensive investigation to find out the base.
Li Jizhen town for all industrial enterprises, restaurants, vermicelli processing plants, farms and other coal-fired boiler with a boiler units diagnostic investigation, the establishment of coal-fired boilers ledger, so base-clear, the situation is clear.
Second, clear standards, conducting pressure.
Town leaders organized the renovation work conference of coal-fired boilers, the boiler so that the user's overall reform and the dismantling of scheduling, the town must be eliminated in the formation of boiler upgrade, you do not need to be removed out of shutting down consensus.
Third, actively coordinate, and assign responsibilities.
Natural gas is being implemented in conjunction with the "double substitution", and actively coordinate the gas boiler equipment suppliers in collaboration with the local gas company, entered into a collaboration, timely completion of "substitution of gas for coal" upgrade tasks.
As of now, the town has shut down six coal-fired boilers, the implementation of "substitution of gas for coal" boiler upgrade eight, effectively promote the prevention and control of air pollution.
The frequent attacks on haze weather since last year heralded that the atmosphere had to be managed. Coal emissions are regarded as the culprit of the formation of haze, so the coal-to-gas plan has entered a high-speed growth period in an all-round way. At present, the transformation of natural gas boiler has become the hot first choice for investment environment management industry. According to reporters understand, so far for coal-fired boiler demolition and phase-out has entered a substantive phase of implementation. Since entering the second quarter, many places in the country have issued measures to remove and reform high-pollution coal-fired boilers, and a war of annihilation of coal-fired boilers has been launched in an all-round way. The correlation analysis shows that under the background of energy saving and environmental protection, coal to gas will become the next few years. As a substitute for coal-fired boilers, natural gas boilers will also usher in a high-speed growth period. In addition, the reporter learned that since the second quarter of 2013, in addition to Beijing, Zhengzhou, Xi'an has also dismantled 194 coal-fired boilers; Construction, environmental protection, municipal and other departments of Lanzhou City to reform the urban coal-fired boiler projects jointly approved, has started to demolish 83 units of 1518 steam tons, accounting for 40% of the total task of dismantling; Urumqi, Xinjiang, has put coal into the people's livelihood project as the top priority in the construction of beautiful Xinjiang; dozens of heating stations in Tibet are also actively carrying out the transformation of gas-fired boilers; Jiangsu Jiangyin, which is heavily energy-consuming, has also stepped into clean-energy applications, with 100 coal-fired boilers scheduled to be phased out by the end of the year. As a result, the coal-fired boiler gas conversion project has entered the high tide period.
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 °.Free Chat
