dzl solid fuel fired hot water boiler

February 20, 2019, the Beijing Municipal Government issued the "Beijing's pollution prevention campaign of 2019 Action Plan" (hereinafter referred to as the "Action Plan"). "Action Plan" clearly 2019 development goals: the first is the city PM2.5年均浓度, three-year moving average concentration strive to continue to decline.

Since 2018 autumn and winter, fog and haze in control efforts continue to increase. Beijing, Tianjin Fenwei Plain, the Yangtze River Delta region of the focus of supervision and maintain a high pressure situation, provinces and cities have also introduced Blue Sky Battle plan, air pollution control sector welcome the opportunity. And because the 2018 autumn and winter abolition of green "one size fits all", so that pollution from the administrative means to switch to environmentally friendly means to speed up environmental protection business orders release.

"Winning Blue Sky Battle three-year action plan" called for increased efforts to eliminate small coal-fired boilers, the county level and above urban area basically eliminated 10 tons of steam per hour and coal-fired boilers, in principle, to the new 35 per hour tons of steam coal-fired boilers. We believe that, under constant fog and haze, the small boiler phase-out process will accelerate. Research believes that by 2021 the transformation of coal-fired central heating investment 88.6 billion yuan, annual operating income of 240 billion yuan, the central heating market will also speed up the release with the environmental supervision.

Professionals expect non-electric air control about 192.2 billion market space, ultra-low emission thermal power market reform space of about 65.7 billion yuan, the whole vast air pollution control requirements.

In addition, the high diesel vehicle emissions, is also one of the main source of haze pollution. Considering the number of ministries had jointly issued by the Ministry of Ecology and environment "diesel truck pollution control tough fight Action Plan" diesel vehicles, boats become the focus of the next step of action to win the Battle of the blue sky.

As early as abroad in the 1970s had developed exhaust gas temperature is 40 ~ 50 ℃ condensing gas boiler. The so-called condensing gas boiler is to use a condensing heat exchanger in the exhaust gas boiler steam condenses down, in order to achieve improved thermal efficiency boiler, gas boiler to reduce pollution. Since the fuel gas in the boiler used in most of the hydrocarbon, the higher the flue gas water vapor content, and is much larger than the coal-fired boilers. If the exhaust gas temperature is higher than the flue gas dew point temperature, water vapor as latent heat of the flue gas drained, it will take away a lot of heat. In North Shaanxi an example, wherein the hydrocarbon fraction accounted for 95.5% by volume, containing a large amount of hydrogen in the fuel element, the exhaust contains large amounts of steam, if the temperature is lowered to a dew point temperature of exhaust gas, the exhaust in the flue gas recovery section sensible heat and latent heat of the steam, the thermal efficiency of the boiler can be improved 1O% to 15%, a considerable number.

Gas dzl solid fuel fired hot water boiler controller function analysis of gas hot water boiler product introduction gas hot water boiler can satisfy the heating and hot water supply. If the heat exchanger in the pipeline hoisting decency, the boilers to meet a predetermined bath and warmed simultaneously. Gas hot water boiler with obvious environmental protection, energy-saving properties, Security Council, and other intelligence operations, very convenient. In addition, since the operation of rationality and incentives the government of the New Deal, gas hot water boiler Everybody increasingly been pro-gaze. Gas hot water boiler controller function of resolution. 1, Encyclopedia Chinese Patent liquid crystal display, embedded luminous incandescent lamp, noon, night, regardless of the display contents at a glance 2, animation image as significant level, the heating, the valve case, an alarm situation, well known boiler 3, cpuU automation 中央处理器 all intensive program on a number of sub-integrated ic, ease of use, high intelligence level, use simple variable, fully functional. 4, with the time setting, temperature setting, setting valve for setting, automatic setting, etc. actuated to set the pressure, set free working efficiency. 5. With low water level alarm (anti-aircraft firing), high temperature alarm, Gao pressure alarm, a chain support capabilities (shutdown) and other alarm action to remove security risks. 6. detailed self-diagnosis, record and store alert messages, free to check the alarm condition is conducive to regular inspection and maintenance.

Under what circumstances condensing boiler energy efficiency standards higher thermal efficiency condensing boiler is very high, as a professional domestic condensing boilers in actual use, the efficiency of the boiler can be higher, these are some of the work done by the actual use . So we under what circumstances, how to use condensing boilers in order to achieve greater thermal efficiency of it? Here's what to do a brief analysis of introduction. First, at a relatively low temperature operating conditions of a high thermal efficiency of the host condensing boiler heating system is water temperature can be adjusted during use, the water temperature can be set according to the terminal configuration. Obtained through many experiments and consumer feedback derived from the condensation boiler higher thermal efficiency at a relatively low temperature operating conditions. Second, at lower output power higher thermal efficiency. In use, we will condensing boiler water temperature set, then automatically controls the combustion boiler according to the temperature of our set, when the temperature approaches the set temperature, the boiler gas valve opening degree of the motherboard emitted signal decreases, the automatic the flame is reduced to the role of maintaining stability and temperature. Thus described, condensing boilers at a low output power higher thermal efficiency. Third, to maintain a certain temperature difference between flow and return of the circulating pump can be improved in thermal efficiency condensing boiler heating system used is a keep up the flow of water medium, so that the high-temperature water in the boiler to the end device comes out. But the circulation pump in the boiler is a certain speed, that is, no matter how much power in a condensing boiler combustion, a circulation pump is always in operation speed, the use of variable frequency pump, pump speed changes with power boiler changes, it will make flow and return temperature is maintained constant temperature difference, so to maintain a certain temperature difference between flow and return of the thermal efficiency can be improved. The above circumstances is about how to improve the efficiency condensing boiler, only use efficiency, and then in the course of professional condensing boiler can be more prominent this article to introduce its value, and thus give consumers better experience. All consumers in the use of condensing boilers may wish to do it through a few adjustments to improve the efficiency of the boiler.
