Boilers in the paper industry are used to generate steam for power and process systems. High pressure steam is generated for steam turbine generator sets to produce electric power. Medium and low pressure steam is used for various process heating applications such as heating and softening pulp wood chips for further reduction by chemicals to make wood pulp.
10th June this year, the provincial government agrees that the ecological environment in Zhejiang Province Office issued the "Notice on the implementation of special emission limits national emission standards of air pollutants" (hereinafter referred to as "notice"), marking the full implementation of Zhejiang Province especially national emission limits of air pollutants.
"Special emission limits" is mainly for land development density is already high, the environment carrying capacity began to weaken, or less atmospheric environmental capacity, ecological environment is fragile, more stringent prone to serious air pollution problems in sensitive areas and set the emission limits. Implementation of the national emission standards for special emission limits, Zhejiang Province in favor of further strict pollution management, reduce pollutant emissions, to further improve air quality, but also help promote the integration of the Yangtze River Delta environmental standards.
In fact, back in 2013, Zhejiang has already begun in some areas particularly the implementation of the national emission standards limit emissions of air pollutants, but was limited to Hangzhou, Ningbo, Huzhou, Jiaxing and Shaoxing, Hangzhou Bay five cities; and this is to expand to the province level. In addition to a wider geographical range, "advertisement" clearer pollutant emissions targets, e.g., volatile organic contaminants not individual indicators, including not only non-methane hydrocarbons, total volatile organic compounds such as benzene, benzene and other pollutants indicators meet the definition of volatile organic compounds should be performed; also more involved in the industry, such as boilers only provides original coal-fired boiler, and "notice" it covers all types of boilers (including oil, gas).
It is reported that, in the national emission standards have been implemented, a total of 25 standards set emission limits of air pollutants in particular; at the same time, the recent ecological Ministry of Environment and the State Administration of market regulation has released three national emission standards of air pollutants, namely, pharmaceuticals, paints, inks and adhesives and volatile organic compounds fugitive emission control standards, and will be from July 1, 2019 implementation. According to "notice" requirement, the province is also involved in the enterprise should implement special emission limits specified in the three standards, the execution time of the emission standards time synchronization. Provincial Department of Atmospheric environment Department official said: "The implementation of the national emission standards for emission limits in particular, help to further strict management of our province pollution, reduce pollutant emissions, to further improve air quality, but also help promote environmental protection in Yangtze River Delta standard integration.

Plants use existing ordinary way for the steam boiler steam solutions for problems: 1, big waste of energy: pipeline transport long distance, large energy loss. Steam from the steam boiler plant to have many points have become a condensate. Especially at night discontinuous steam plant, each with steam before the need to discharge large amounts of condensate, resulting in waste of energy. 2, managers and more: Boilermakers need to arrange several on duty holder, increased labor costs. 3, beautiful plant has been greatly affected. Henan fast boiler recommended method: point - point steam supply way, needs to be placed side by side Henan steam boiler plant or equipment fast steam boiler, with the open with the use. Complete cancellation of the factory steam pipe network. And highlight the advantages of a conventional steam boiler: 1, Energy saving: Due to put an end to the pipeline transmission losses, energy-efficient way than conventional steam supply energy by 30-50%. 2, management is simple: Henan fast boiler industrial high efficiency steam generator boiler does not belong to the range of pressure that can be placed directly on the shop floor, without making a separate boiler room. When steam required by the plant workers can boot. 3, the plant more beautiful.
Xiao Bian tell you about the boiler combustion optimization control of those things: the boiler is an energy conversion device, in other aspects of power plant systems have been developed under perfect circumstances, boiler combustion system is a major part of energy-efficient coal-fired power stations and savings. Now, with the burner technology is improving daily, it has been able to adapt to all kinds of fuel combustion conditions and load, but the new requirements of energy saving power companies makes burning power plant boiler combustion stability not only meet, but also to meet the combustion process efficiency and reduce pollutants requirements emissions. It is necessary to further optimize the combustion process and operation. Today, we learn more about it. Generating hot water or steam boiler may directly provide the necessary heat for industrial production and the people's life, by a steam power plant can be converted into mechanical energy, or through the generator converts the mechanical energy to electrical energy. So, generally we use combustion expert system to monitor the implementation process, maintaining the boiler combustion efficiency and energy saving. Automatic water boilers, reaching full of water replenishment stops automatically, not manned, save time, save time, effort, labor. Increasingly comprehensive boiler combustion control means and the cumulative operating experience, providing adequate conditions for the implementation of expert systems. By burning power plant boiler combustion expert system of real-time status monitoring, by the mathematical model and expert system established by the corresponding combustion, can effectively adjust the boiler combustion, state correction due to various factors to the combustion process caused by deviation, to achieve optimal control of combustion. Structure designed according to the boiler pressure, provided through the top of the large pores, the boiler operates at atmospheric pressure, away from the danger of explosion; boiler furnace using computer simulation to optimize the design, the size of the boiler is fully optimized, so that coordination aesthetic aspect. When using the boiler operation, hold down the control key forced to manually start and stop the boiler with water, the water level reaches very low safety level, the boiler automatically stops pay, the microcomputer controller after setting the boiler, the boiler began to work fully automatic, automatic replenishment, automatic heating, when the set temperature is reached, the boiler into the automatic insulation state. The coal boiler according to data analysis, secondary air damper temperature, and the load carried by the boiler combustion conditions, the coal and air flow control system to protect combustion boiler at its best, achieve fuel economy, reduce emissions of pollutants. The experience of the steel and building materials industries, the expert system can be achieved using combustion burn energy saving 2% -5%. You know what Btu boiler is not it?
2020-5-23 · A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.Get A Quote
