Select heating entholphy steem table with boiler pressers what are the considerations for the heating system, we propose the functional principle of the boiler and a lot of doubt, this simple to explain: household independent heating system, the first essential is a stable heat source, that is, heating boilers for the family is a simple heating boilers, for it is a city or a region, we need a lot of heating boiler heating stations were running protection of the public. 1. The inner two energy saving boiler combustion process, combustion of a fuel itself, and the other is to produce the fuel gas flammable mixture in a sealed high-temperature gasification and combustion processes. Boiler reasonable structure, the fuel gasification process stability, integrity, and the use of anti gasification burner, arranged dedicated economizer. Up to 85% thermal efficiency of the boiler, energy-saving effect. 2. The water temperature and water flow constant water temperature, no, no, no change, is a measure of the boiler is the main quality standards. Old residential water heaters commonly large amount of water or less, high or low temperature. According to a company's HVAC engineer, boiler now only one instead of the old heat exchanger, gas and water flow ratio control is not an exact match. But today's new boiler using a secondary heat exchanger. By completely secondary heat exchanger, complete remission contradiction gas two-phase flow of water, the water temperature is fairly constant, the flow does not change. 3. easy to control a good control system is an effective guarantee the normal operation of the combustion safety, testing, maintenance, daily operation and failure analysis are all important. Therefore, the choice of high-performance boiler is particularly important, especially for the elderly and children in the home. By-room temperature control not only the freedom to set their own needs heating temperature, can also be pre-set temperature before returning home, so that they will be able to enjoy the warmth of a home. 4. Look for boiler service procurement business, buying boiler products, especially large tonnage, is perfect after-sales service is an extremely important factor. In fact, due to the imperfections of production and after-sales service network, many boiler brands in the market is difficult to guarantee. Business and professional services to improve network and service system, not only the performance of enterprises and planning, more attention is to look at business and professional ability, each link is a professional, to ensure efficient and smooth transition of the whole process.

How to choose a good quality gas entholphy steem table with boiler pressers and can use without water? Gas-fired boiler, which is a specific kind of boiler, but also in the product website, it is necessary to be familiar with and understand, well familiar with the site and its manufacturing factory. So, the next job is to learn a gas boiler, at the same time, we also acquire some professional knowledge, and apply their knowledge to realize this knowledge, to avoid waste from. 1. How to choose a good quality gas boilers? Want to choose a good quality gas boilers, is the need to do two things, are as follows: First, we must clearly understand the needs, determine their products can bear the price range, good further refine your selection; second is to choose professional formal manufacturers, to ensure good product quality and good performance, in turn, make the product have good results. 2. boiler room gas boiler which notes? Boiler room gas boiler, which is some notes, which specifically is: this kind of boiler operation must be carried out by the Boilermakers. During operation of the boiler, boiler worker must be on duty to patrol the site, it is strictly prohibited unattended operation. Instead of boiler-related staff, does not allow unauthorized access to the boiler room, to avoid any danger. 3. When you use gas-fired boilers without water? If you can use when gas boiler without water, it is mainly determined by the actual situation, if not dry gas boiler system, can be used normally this kind of boiler. Gas boiler system has been the lack of other issues arise if without water, the boiler does not work, then you must stop the shutdown. So, at this point, we should have a correct understanding, there can be misconceptions, so as not to affect the normal use of the boiler. 4.1 tons of gas hot water boiler and 1 ton gas steam boiler, its gas consumption per hour of the same? 1 ton gas hot water boiler and 1 ton gas steam boiler, its gas consumption per hour from a professional point of view is not the same, one ton of gas hot water boiler, its gas consumption per hour is 80 cubic meters, and one ton gas steam boiler, its gas consumption per hour is 75 cubic meters, so this will have a conclusion based on the above.
It reads as follows:
Municipalities (including Dingzhou, Xinji) people's government, security male New Area Administrative Committee:
In order to further deepen the boiler pollution control, reduction of nitrogen oxide emissions, improving air quality, win the Battle of the sky, it now follows nitrogen oxide gas boiler notice governance:
First, we attach great importance to understand the situation, do a solid job governance
Nitrogen oxide gas boiler control, is to win the Battle of the sky, to promote an important measure to further improve the quality of atmospheric environment, is to deepen the air pollution control efforts around one main direction, is an important part of governance to deepen the boiler, the province's existing gas 10,790 tons of steam boiler units 37318, 23838 9,932 tons of steam wherein steam 10 tons / hr or less and a gas boiler, substantially free of nitrogen oxides into the process, the nitrogen oxide emissions of about 38,500 tons, the average concentration of about 150mg / m³.
Meanwhile, the province average concentration of nitrogen oxides is high, annual average concentration of nitrogen oxides is much lower than the rate of decrease of sulfur dioxide, haze is generated, among the major causes of the high ozone concentration.
Beijing and Tianjin to the surrounding gas on boiler control arrangements, and achieved initial success, Beijing completed the transformation of low - NOx combustion gas, nitrogen oxide emissions concentrations within 30mg / m³, the total emission reduction of 80%; Tianjin local emission standards promulgated boiler air pollutants, nitrogen oxide emissions concentrations within 80mg / m³.
Localities must deepen understanding, with a strong sense of political responsibility and the courage to act in the spirit of reinforcing initiatives, compaction responsibility to carefully organize governance, and make new contributions for winning the Battle of the blue sky.
Second, focused, clear goals, and win the battle governance
All localities should strengthen awareness of time, reasonable arrangements to ensure on schedule to complete the task, to the end of June 2020, the existing non-electric gas steam boilers, hot water boilers, Stoker stoker furnace and completed the transformation of low-nitrogen combustion, soot, sulfur dioxide and nitrogen oxides reach 5mg / m³, 10mg / m³, 30mg / m³, the new gas combustion boiler synchronizing means and is mounted low nitrogen meet emission standards. 20 tons of steam / hour or more gas-fired boiler to install air pollution automatic monitoring facilities and networking with the environmental protection department, install a distributed control system (DCS system). 20 t steam / hour to install the nitrogen oxide gas boiler exhaust gas analyzer, a field inspection data should be able to provide emission monitoring at least one year.

For failure to complete the task of transformation on schedule, annual nitrogen oxide concentration in excess of the provincial Department of Environmental Protection will suspend approval of the EIA nitrogen oxides new construction project documents in addition to the people's livelihood projects. Localities should also strengthen organizational leadership, the implementation of the task to the responsible units and responsible job, strict accountability assessment.
(B) increase policy support. Formulated "Boiler Air Pollutants Emission Standards Hebei Province," received strict emission limits of pollutants. Governance throughout the project through acceptance of appropriate subsidies in integrated financial subsidies to control air pollution. Simplify the EIA approval process, gas boiler combustion of low nitrogen transformation refer to "construction project environmental impact assessment of Classification Catalog (2017 version)," projects related to the registration form online record management.
(C) to strengthen law enforcement and inspection. All localities should follow a comprehensive air pollution control requirements, supervision and law enforcement to carry out special checks on overdue fulfill the task be ordered to stop production of governance, strengthen the daily supervision of completed projects to ensure stable discharge standards. For excessive emissions, fraud, unauthorized outage environmental protection facilities, waste-water treatment snuck issues such as rectification and punishment according to law; wrongdoing, be held criminally relevant personnel.
(Iv) strengthening quality management. Municipalities and counties should strengthen the technical capacity of equipment manufacturers, project progress, acceptance monitoring, supervision and management of funds, select the technology is mature, with good results, there are success stories of the equipment manufacturers. Strengthen social management of the testing organization, supervision and tissue sampling tests and test results to ensure project quality.
For a long time, Hebei Province as the country's most polluted regions, gray haze is normal people's lives. Hebei Province, north of Yanshan, west of Taihang Mountains, was a famous country poised; but in recent years, due to the production process to run some heavy steel mills, cement plants, thermal power plants and other chemical companies, emit large quantities of harmful substances into the air, Over time, the increasingly serious air pollution, haze follow.
The notification transformation of low nitrogen gas boiler, the boiler will be put on nitrogen means lower environmental protection, and promote air governance, Hebei Province, to realize the dream of the blue sky.
