automatic vacuum gas fired steam boiler

Recently, we learned, Shaoxing City, Zhejiang Province People's Government Office issued the "coastal city 2018--2019 autumn and winter tackling air pollution comprehensive management action plan", as follows.

Less adopt comprehensive measures to reduce coal total coal consumption, coal consumption in 2018 to ensure that the total amount of negative growth. New non-owned coal-fired units, the implementation of new large-scale coal-fired units and coal consumption capacity equal or reduction alternative.

Optimize the use of natural gas structure, in principle, to new natural gas cogeneration and gas chemical projects, gas will adhere to the reform, orderly manner "coal to gas" project.

Carry out boiler (with tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) an intensive investigation to establish accounting and inventory management, to develop a comprehensive remediation program in accordance with the unified deployment requirements boiler city, according to the law in accordance with regulations to increase fuel coal boiler out of efforts to achieve all cleared 10 steam tons / hour and coal-fired boilers to prevent high-polluting fuel boiler rebound has been eliminated. Boiler registration strictly prohibit new steam per hour 35 tons / hour of coal-fired boilers, coal-fired boilers new emission concentration to meet ultra-low emission of air pollutants, strict control of new biomass boilers, coal-fired boilers embodiments and low nitrogen urban built-up area of ​​ultra-low emission biomass boilers transformation.

Comparison of thermal efficiency of two boilers: 1, vacuum boiler The water volume is small, the primary water does not participate in the system cycle, the number of start-up times of the burner is more than that of the normal pressure boiler, the combustion heat efficiency of the burner is low, and the thermal efficiency of the vacuum boiler is up to 91% under the premise of stable vacuum degree. The change of vacuum caused by the unstable operation of boiler auxiliary equipment will also reduce the thermal efficiency. The operating cost can not be stable, and the thermal efficiency decreases with the decrease of the service life of vacuum pumping equipment and control components and the increase of failure rate. 2, atmospheric boiler The hot water volume is larger than the vacuum boiler, the primary water does not participate in the system circulation, the burner starts up less times, the burner combustion heat efficiency is high, the hot water boiler thermal efficiency is also 91%, and the thermal efficiency of hot water boiler is stable in operation. There is no effect on the failure rate of so many devices, and the structure is simple and durable.

Gas-fired automatic vacuum fired steam boilers of different types and their advantages on the common market gas steam boiler model, what does? According to data accumulated over the years, the statistics, the results are as follows, for your reference to understand. WNS fuel gas steam boiler, low cost, the implementation of the pipeline, so that lower gas prices, fuel cost decreases; the model of high boiler combustion efficiency, fuel savings, investment buying low fuel costs; the whole side pull butt welds, boilers the use of safe, long life, low maintenance costs. High efficiency, there is arranged a tail flue gas condensation recovery, can effectively control the exhaust gas temperature, high thermal efficiency of the boiler; using automatic burner, water continuous electric adjustment, high combustion efficiency. SZS fuel gas steam boiler, with international popular three-pass shell type, all wet back structure, large volume combustion chamber design, burning more fully. Internationally renowned burner, combustion chamber all-corrugated furnace structure, both to strengthen the flue gas disturbance, but also increases the radiation heat transfer area. Not only increases the stiffness of the furnace, and effectively weaken the expansion stress of the furnace; enhance both heat transfer, but also to promote the fuel combustion within the furnace. Vacuum gas hot water boiler, high safety, vacuum boiler because the phase change medium flow system below atmospheric pressure, absolute pressure inside the unit is running is 0.02 ~ 0.08MPa, the unit is in a vacuum state, and thus the explosion does not occur. Long life, internal boiler fouling does not occur, increasing the life of the boiler use. Heat exchanger portion with stainless steel, corrosion-resistant, the design service life of 20 years. High degree of automation, the use of the control device and mechatronic joint control programmable logic controller. Long life, scientific product design, advanced processing technology and strict quality control, all factory production of boiler equipment. The advantages of gas steam boiler in recent years reflects the more comprehensive. Exacerbate air pollution causes the gas steam boiler into the market faster. Gas-fired steam boiler is a clean energy, natural gas fired industrial boilers, and with the traditional burning of fossil fuels such as coal boiler has unparalleled advantages in comparison. Natural gas boiler steam boiler market development trend in the future, the future market development of industrial boilers except by factors affecting the pace of development of our national economy and the scale of investment, etc. In addition, more and more restricted energy policy and energy-saving, environmental protection requirements.

Laohekou vacuum hot water boiler which company is good for the present domestic vacuum hot water boiler manufacturer, according to different power, have their own advantages vacuum hot water boiler sample. It does not save the difference between the vacuum hot water boiler is really a problem of standards covering what. In general you want to correct selection suitable for use in all enterprises vacuum hot water boiler, as several indicators must understand the following: First, the energy consumption of two vacuum hot water boiler, vacuum hot water boiler output start time three vacuum hot water four specified power boiler, hot water boiler type vacuum more than a few indicators are certainly buying a vacuum hot water boiler in the usual non-compliance, and most certainly seriously consider non-compliance, from several indicators, should see a group of vacuum hot water boiler is stable or not really a problem, of course, the selection of vacuum hot water boiler, when you find the most suitable business, cost-effective vacuum hot water boiler is the most important.
