Atmospheric gas nature fired hot water boiler several parallel operation policy in general, for a single heat atmospheric gas hot water boiler is relatively small, in order to meet the large heat load operating conditions, you need to run more than one parallel, then the two Taiwan atmospheric gas hot water boiler Weili, a simple energy-saving operation policy resolution. (1) temperature is below the water pipe network two temperature control curve setting value, to ensure a water supply pipe network without changing the temperature, by increasing the flow rate of a network to increase the heat supply until the electric control It is increased relative to the valve opening degree of 100%. In this process, by increasing the heating capacity of each atmospheric gas hot water boiler to meet heating needs. (2) Conversely, if the water temperature exceeds the pipe network two thermostat setpoint curve, at a constant temperature of the water pipe network of the premise, to reduce network traffic by reducing a heat supply pipe, in which the case, each sub-volume pressure hot water boiler heating by reducing the heat input per gas hot water boiler pressure and thus reduce the temperature of the water pipe network two. (3) When a plurality of atmospheric gas hot water boiler select start and stop the object by running the length of the cumulative duration is determined, the accumulated run time of the shortest atmospheric gas hot water boiler startup priority. In short, during the development of atmospheric gas hot water boiler operation strategy of several parallel, taking into account the issue of energy-efficient operation, during which the comparative analysis to be certain, and merit-based election.
The difference between the saturated steam and superheated steam boiler steam Free Free subject supervisor monitoring the subject steam boiler, that is, the water is briefly heated to a certain extent, the occurrence of high-temperature steam industrial boilers, users can use steam from an industrial production according to the needs of perhaps heating heating. This section steam boiler lower acquisition costs, it is also appropriate to use convenient, especially gas steam boilers and biomass steam boiler, use clean energy for incineration, low fuel cost, non-polluting cleaning. Since it is a steam boiler steam intent to obtain high-quality thermal energy equipment, it heard steaming can happen divided into two types, that is, full steam and superheated steam we now say. 1. Steam is full and full steam heating water steam we can directly obtained. Full steam pressure and temperature, the density is one to one, one atmosphere steam at a temperature that is 100 ℃. If demand higher steam temperature, steam pressure only progress on the line. 2. The superheated steam superheated steam is reheated steam on the basis of full, i.e. reheating steam abilities occur. When water is present, the superheated steam is not occurred, since the water will absorb more heat steam generation. Temperature and pressure of the superheated steam is not corresponding. . As can be seen from the above, the temperature of the steam and full steam pressure is substantially proportional to, the greater the pressure, the steam temperature will be relatively higher, since the user can conditioner according to a demand.
Coal occupies a large part of our energy economy, but coal brought sulfides, carbides, dust, ash and other harmful substances are also severely affected the people's living environment and ecological environment. At this stage, China's major provinces and cities in the related industries of coal fired boilers released specific remediation programs. By treatment of coal-fired boilers, can effectively promote air pollution control and bulk coal governance work.
Hebei Province was polluted our province, many kinds of heavy industries, heavily polluting enterprises, geographic and congenital conditions are not conducive to the spread of pollutants, and other factors lead to high emissions of air pollutants in Hebei Province.
In recent years, Hebei Province, through the management of coal-fired boilers, the "coal to gas", "coal to electricity", and many other measures to enhance the governance of the ecological environment, improve people's happiness index of blue sky. According to statistics, as of the end of October this year, Hebei province has eliminated emissions of less than 35 steam tons / hour (including 35 steam tons / hour) coal-fired boiler units 6492, a total of 12744 tons of steam, respectively, to complete the annual task of developing 96% and 95%; for the emissions amounted to more than 35 steam tons / hour of coal-fired boilers transformation process, has been the transformation of 158 units totaling 12185 tons of steam to complete the annual task of developing 70% and 95%, respectively.
Future, Hebei Province will continue to carry out renovation work on coal-fired boiler more specific details of. Through the establishment of this ledger management mode, regularly check and keep track of coal-fired boilers governance; development of special treatment programs to strengthen the "coal to gas", "coal to electricity" transformation content; relevant policies to achieve strong support and assistance encourage.
This year, the environmental protection departments in Hebei organize multiple ecological environment and comprehensive management of air pollution inspection work, as one of the key phase out coal-fired boiler inspection work has been widely attention. For no control measures, emissions exceeding the bulk coal fired boiler, remediation process according to the law or banned.
Hebei Province will further improve control efforts obsolete coal-fired boilers. The next stage will be formulated "boiler emissions of air pollutants, Hebei Province, local standards," for the local coal-fired boilers do not meet the standards of remediation and prevention measures to strengthen inspections of coal-fired boilers have been eliminated to prevent burning complex phenomenon occur.
Maintaining the environment and sustainable development is an important prerequisite for China's economic and social development. The provinces and cities in response to national policy development environment, make specific control measures, Hebei provinces and cities will also combine their own situation, the air pollution control work carried out in the end.
The difference between low nitrogen gas boiler with ordinary coal-fired boiler from China after the latest air pollution emission standards introduced across the country have carried out air pollution control projects, ordinary coal-fired boilers due to serious pollution faced elimination and replacement process. Low nitrogen gas boiler because of its unique low nitrogen, clean, environmental advantages, namely a push into the market has been widely welcomed. Today, fast boiler come to you talk about the difference between natural gas boilers with low nitrogen ordinary coal-fired boilers. 1, differences in emissions due to the use of ordinary coal-fired boiler fueled by coal, according to the composition of coal, which determine the more discharged flue gas after the combustion of soot, ash, sulfides, flows into the atmosphere can result in serious pollution influences. A low nitrogen gas boiler using natural gas as fuel, almost no soot and other harmful substances combustion; low nitrogen after processing, harmful substances is reduced to a negligible extent. 2, ordinary coal-fired boiler combustion technology differences are mostly fed directly into the furnace of coal combustion, incomplete combustion of coal will be an inconvenience. Low nitrogen gas combustion boiler made a change in the natural gas and oxidant gas (air) are mixed in a certain proportion of advance before entering the furnace, so that the gas will be more fully combustion, fuel efficiency is also improved. 3, differences in the safety factor by coal-fired boiler explosion occurred in recent years across the country, we can see that a lot of coal-fired boilers there are still security problems, once the risk of an accident, whether it is physical security or economic interests will suffer great losses ,The consequences could be disastrous. A low nitrogen gas boiler for safe disposal can be seen in the following points. First, fuel storage and delivery are established directly connected to the pipeline, and the pipeline have done more treatment, both the quality and safety factors have been improved. Secondly, the current low nitrogen gas boiler mostly have joined the intelligent automatic control system; it just as fast boiler, each boiler is equipped with independent research and development of intelligent control system, with matching boiler is very high, people fireman only need to follow the instructions HD display menu operation, start to finish, adjust a variety of state (water supply, output ...), outage, etc., and easy to operate but also to avoid direct contact with the staff of the boiler. In addition, low nitrogen gas boiler with a comprehensive probe detection device, connected enterprise cloud services remote monitoring system, water level, pressure, temperature and other abnormal occurrence which step will be detected immediately and begin warning to remind people immediately see the boiler status fireman . Continuous technological innovation, is providing energy saving, high-quality boiler equipment lies. Low nitrogen gas boiler after many trials and engineering applications, and achieved great results; at present, has been widely used in many industries, not only protects the environment, energy conservation, but also to control the pollution, the technology is particularly worth the continued research and development applications.Free Chat
