16 ton steam boiler price steam boiler in china
(A) General requirements: 1. In submitting applications should be an independent legal entity. 2. Where the application for a Class A boiler manufacturing license of the enterprise, application should hold Class B boiler manufacturing license, and should be more than five years of B-class boiler production history. 3. Proposed business license application approved trial produced A-class boiler products. 4. Production and operation status, without design, manufacturing quality of a major accident.
Boiler header is quick to install and what boiler: a boiler for this important product website and keywords, if we are not very familiar with and understand, then, is concerned about the site, and through a number of related articles, and to become familiar with understand the product, and at the same time, to increase their expertise in this area. In this way, you can learn at the same time, to achieve the correct use of the boiler, in turn, make their own benefit. 1. boiler header, which is what? What their role is? Boiler header, which from a professional standpoint, then, which means a lot of heating surface tubes are connected and a larger diameter tube, typically of seamless steel tubes, and two welded end cap. Further, there is a hole thereon so as to weld the tube or other expanded joint. Headers of action, or a collection of working fluid dispensing soft drinks, and also, reducing the number of connecting pipes and transport drum opening of the working fluid, so that the safety can be effectively improved the performance of the boiler. Therefore, it is not a separate component, but by these members waterwall, economizer and superheater or the like thereof. 2. The boiler flue gas temperature, which is why appropriate? In addition, the water capacity of the boiler, if there are requirements? Boiler flue gas temperature, which should be controlled within an appropriate range, because if the exhaust gas temperature is too low, it will cause boiler corrosion occurs at low temperature, and the exhaust gas temperature is too high, it will reduce the thermal efficiency of the boiler. So, just to be controlled within an appropriate range, in general, is in the range of 150-250 degrees Celsius, more appropriate. And the boiler water capacity, there is no specific requirements, the main, it is to see a fuel heat.
Refers condensing heat recovery technology, a condenser disposed in the boiler flue tail, the high temperature flue gas discharged latent heat through the condenser, the condenser and then the flue gas prior to the recovery boiler portion back to the boiler for reuse, can be sufficiently improved thermal efficiency of boiler and thermal energy utilization, have its cake.
Recently, Chengdu issued the "2019 Chengdu air pollution prevention and control action plan" to optimize adjustments programs around the industrial, energy, transportation, land use structure, proposed Yajian coal, pollution abatement, control car cut oil, clean dust, haze rule technology, integrated law enforcement operations as well as six 50 detailed measures.
According to the provincial government issued the goal of improving air quality in 2019, Chengdu PM2.5年均浓度控制在 year 52 micrograms / cubic meter and below, the number of days of good air quality rate of 67.6% and above.
Chengdu six proposed action, emphasizing the Internet technology means to achieve "smart governance gas": First, accelerating into the key source of business to install online monitoring equipment; the second is the full implementation of the wisdom of the site management platform in the city's housing construction and municipal construction site, to build green construction demonstration sites; Third, establish and improve municipal departments emissions inventory information sharing liaison mechanisms and environmental systems City - District - the town (street) three emission inventory liaison mechanisms; Fourth, focus on road vehicle emissions, drawn dynamically updated mobile source pollution maps.
At the same time, promote green industrial development, increase efforts to eliminate high energy consumption and high pollution industries: on the one hand, continue to promote coal-fired boiler, "clear" work; in an orderly way in key areas of old gas (oil) boilers implementation of clean energy transformation; increase industrial furnaces efforts to eliminate non-compliance. On the other hand, the promotion of green travel, speed up the process of rail transit; in public transport, sanitation, landscaping, postal and other fields of new energy vehicles, accelerate the construction of charging (change) station, charging pile.
