china industrial steam boiler price
High temperature or below the rated temperature of the device, will have a bad effect. If the temperature exceeds its rated value, the boiler will cause overheating of the relevant metal material, material creep acceleration, will shorten the life of the boiler. If the temperature is too high, but some of the key components of the boiler would cause damage, can also cause serious and even superheater tube rupture. If the temperature is lower than the rated temperature, vapor enthalpy is reduced, increased air consumption, decreased economy. This will reduce the thermodynamic cycle efficiency of the plant, the steam humidity at the last stage blades of the gas turbine increases, causing erosion and damage to water droplets gas turbine blades, affect the safe operation of the gas turbine.
The standard ASME American Society of Mechanical Engineers, ASME boiler in line with accepted standards of most countries. Such as North and South America, the Middle East, the Philippines and other countries. 1, the European Union as a separate area, in line with PED directive boiler is the basic condition to enter the EU. 2, India is a big country in South Asia, is also a major importer of boilers, boiler if you want to enter India, India must conform to the boiler rules --IBR. 3 Australian states have their own special requirements for boilers, but also must meet AS standards. 4, Malaysia DOSH execution standards, substantially similar to the ASME standards. 5, Russian zone using Chinese standards, but to do a CUTR certified to entry.
Luzhou, Sichuan issued a notice to win the Battle of Blue Sky embodiment. Program requirements, to promote ultra-low emissions to upgrade the steel and cement industries, and increase efforts to eliminate small coal-fired boilers, phasing out the whole 10 tons / hour and below the coal-fired boilers. Details are as follows.
1, to accelerate the development of clean energy. Scientific and orderly promote clean energy development and utilization of hydropower, natural gas (shale gas), wind power, solar, biomass and so on. By 2020, the city's total primary energy consumption of 12.48 million tons of standard coal, total coal consumption control in less than 6.5 million tons, accounting for the proportion of total energy consumption control in less than 42%, the newly constructed and put into operation a large municipal solid waste incineration power plants, garbage power generation capacity of 12MW, a new wind farm installed capacity of 48MW, the development of distributed PV installed capacity of 5MW, the new large biogas 5. Improve the construction of reservoirs for natural gas production and marketing system.
2, to promote the use of clean coal. Efforts to increase coal washing, coal simultaneous construction of new coal washing facilities, supporting the completion of existing coal mines coal washing facilities in accordance with points Area. Improve coal quality and use of standard industrial, commercial coal do not comply with environmental standards required by regulations of coal quality merchandise. Prohibit the circulation and use of low-grade bulk coal, bulk coal investigated and dealt with according to the law without a license behavior. Increase the civil bulk coal clean governance efforts to promote electricity instead of coal, substitution of gas for coal, to promote the use of clean coal, advanced civilian stoves, strengthen civil bulk coal management. Strengthen regulation and control coal use in autumn and winter.
3, to carry out comprehensive improvement of coal-fired boilers. Increase efforts to eliminate small coal-fired boilers. By 2020, the county level and above cities phasing out the built-up area per hour and 10 tons of steam coal-fired boilers, in principle, to a new 35 tons of steam per hour of coal-fired boilers, in principle, to other parts of the new 10 per hour tons of steam coal-fired boilers. Ambient air quality standards are not areas should further increase efforts to eliminate.
4, increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate network and bulk coal fired boilers within the coverage area. In areas not have cogeneration district heating conditions, a plurality of existing coal-fired boilers of small, actively promote the implementation alternative energy.
1 describes the electric boiler, electric boiler automatic intelligent control techniques, unattended; 2, electric boiler work in a flexible manner, it can be set to manual or automatic mode; 3, electric boiler can also need to set the boiler automatic start date, work hours, one day can be set ten different working periods, the boiler automatic, time to start each of the heating elements, the heating element ??? switching cycle, the respective contact time, the same frequency, improving equipment life; 4, electric boiler analog control algorithms: automatic temperature (pressure) the PID, calculation, tracking, to ensure that the pump, the circulation pump start and stop automatically when the load change; can also be manually controlled.
