Vacuum Hot Water Boilers Supplier In Asia

Hebei Cangzhou issued a "special program on the implementation of standards of governance boiler." Emission standards for boiler treatment and corresponding indication made, as shown in details as follows.

First, the standard standard coal-fired boiler

1, before the end of September 2019, within the city of more than 35 tons of steam / hour ultra-low emission coal-fired boilers complete transformation, emissions of major pollutants to achieve ultra-low emission standards (dust ≤10mg / m³, SO2≤35mg / m³, NOx≤50mg / m³).

Before the end of the year 2/2020, the city eliminated 35 tons of steam / hour and coal-fired boiler, stove and stove operating a small coal stove, achieved within the city 35 steam tons / hour and the boiler "No Coal." Reserved 35 steam tons / hour and coal-fired boiler, stove and stove operating a small coal stove implementation of the special emission standards (dust ≤30mg / m3, SO2≤200mg / m3, NOx≤200mg / m3).

Retention of more than 35 tons of steam / h coal-fired boiler to install air pollution automatic monitoring facilities and networking with the environment department, to install a distributed control system (DCS system), real-time monitoring of pollutant emissions.

Second, gas-fired boiler

1, before the end of September 2019, the city completed two-thirds of the total number of units of low-nitrogen transformation gas boiler above. Among them, the central city of all gas-fired boiler and all the city's industrial and commercial gas-fired boilers to complete a full rebuilding mode low nitrogen.

2, the end of June 2020, the conventional gas boiler should be completed by transformation of a low nitrogen combustion, soot, sulfur dioxide and nitrogen oxide respectively 5mg / m³, 10mg / m³, 30mg / m³.

Third, the task

1, increase clean energy alternatives. In areas not covered by central heating pipe network, and vigorously promote geothermal, wind, solar and other clean energy, in an orderly way from coal to gas and coal to electricity, to change the power-based. In 2020, under the conditions of gas supply has been guaranteed, the city eliminated 35 tons of steam / hour and below the coal-fired boilers.

2, increase the coal management and control efforts. Coal infrared video monitoring devices to increase coal quality sampling efforts, to retain the blast furnace coal-fired boilers to be installed, Hebei coal to meet local standards "Industrial and domestic fuel coal" (DB13 / 208102014) non-coal power generation industry quality indicators .

3, strict new boiler access. Ⅲ class urban area and high-pollution fuel combustion zone ban municipal government designated a ban on new coal-fired boiler, a citywide ban on new 35 steam tons / hour and coal-fired boilers, the new 35 steam tons / hour of coal-fired boilers must in line with the municipal government of central heating planning or construction of industrial parks planning, energy efficiency reached AQSIQ "energy-saving technology supervision and management procedures boiler (TSGG0002-2010)" requirements, encourage the use of "energy efficient boiler promotion List" reached the level of energy efficiency standards boiler, pollutant emissions to meet emission standards require extremely low.

Comparison of heat efficiency comparison of two boiler vacuum boiler pressure boiler: 1, the vacuum boiler water volume is small, a water do not participate in the systemic circulation, the burner startup operation more often than atmospheric boilers, burner thermal efficiency is low, the degree of vacuum under the premise of stable, high-energy vacuum boiler thermal efficiency of 91%, the degree of vacuum devices to change operating subsidiary boilers instability will reduce the thermal efficiency. Operating costs can not be stabilized, as the vacuum pumping equipment and reducing the useful life of the control element, to increase the thermal efficiency of the failure rate will be lower. 2, boiler pressure hot water boiler volume greater than the vacuum, nor participate in a water circulation system, less the number of starts burner, burner high thermal efficiency, thermal efficiency of hot water boilers is 91%, and stable efficiency boiler and hot-water operation, no then the impact of multi-device failure rate, the structure is simple and durable. Comparison of the heat exchanger structure is built of a vacuum through a steam boiler heat exchanger, a short warm-up time. U-carrying stainless steel boiler tube heat exchanger, a cleaning may be opened flange, the other end can not be opened can not be completely cleaned thoroughly heat exchanger. 2, the boiler through the water pressure - heat exchange, the preheating time longer than the vacuum boiler water. Built using copper-line boiler tube heat exchanger, there are two flanges, more thorough cleaning. Compare the life of a boiler, the boiler due to the vacuum suction vacuum boiler work, less time to add water to reduce boiler fouling, corrosion and other problems oxygen, due to the boiler closed, water can not once a year dosing maintenance, boiler pressure has also taken advanced international scale, anti-corrosion measures oxygen, the actual life of the boiler and pressure boiler considerable, even if the long life of the body a little, boiler control elements, the service life of the burner can not be too high pressure boilers. 2, boiler pressure hot water boiler with a water softener equipment boiler fouling problems can be overcome, itself an indirect hot water boiler feed water is also very small, sacrificial anodes to reduce the oxygen corrosion protection internationally, annual boiler maintenance dosing may slow down steel oxygen corrosion, boiler plate and the outer heat insulation take a unique two-component embodiment, with water, acid and alkali resistance, oil and other functions, since the insulation adhesive material applied on the boiler body, with the boiler plate to prevent oxygen corrosion in air, vacuum boiler glass wool insulation, can not prevent oxygen corrosion of the steel sheet with air, so the life of the boiler water is not lower than the vacuum boiler 2 times higher, and the life of no basis.

Similarities and differences vacuum hot water boilers supplier in asia and hot water boiler pressure hot water boiler in this analysis of the current one, the use of a vacuum hot water boiler and pressure hot water boiler are many, then vacuum hot water boiler and pressure hot water boiler What are the similarities and differences between it? Now, Xiao Bian take you a simple analysis. (1) Selection of the auxiliary pressure hot water boiler configuration are relatively stringent, the preferred option, and therefore the probability of failure will be relatively small, and need not maintain a vacuum, simply run under normal atmospheric pressure to , the operation is relatively simple, but relative to its vacuum boiler in terms of some of the more troublesome, but, with the continuous improvement of technology boiler, vacuum boilers now have a breakthrough progress on its drawbacks, at present, two each there are various advantages, specifically how to choose, you need to examine the actual situation. (2) during operation of the vacuum boiler to take into account the degree of vacuum kept, the linkage may be necessary correlation means, the degree of vacuum once damaged, there may occur an accident boiler; and pressure hot water boiler does not have this condition, however, If individual users according to the actual situation, without permission will be under pressure to use pressure hot water boiler, and that their safety is another matter. (3) Origin pressure hot water boiler will be more, and vacuum hot water boiler due to technical applications is relatively new, and therefore, can produce and produce operating thermal efficiency, higher operating level, which is part of the good reputation boiler manufacturers. In short, the process of vacuum hot water boilers and pressure hot water boiler in the running there will be many figured the place, we will naturally have many differences, during boiler selection, take me to their strengths, based on the actual situation, The merit-based election

What hospital do with the gas boiler? Gas-fired boilers for hospitals is generally used to supply steam to sterilize or to provide hot water for heating the hospital, a gas boiler to provide steam and hot water simultaneously to meet different needs, but it needs to install heat exchangers achieve. Hospital of Zhengzhou City, a large, began to replace coal-fired boilers to gas-fired boilers to meet the energy saving policies. Hospital which model is more appropriate Gas boiler Xiao Bian recommended several:? WNS4-1.0 / 184-Y / Q, SZS10-1.25 / 350-Y / Q, both gas-fired boiler is a single drum, a double boiler tube, the hospital according to the actual amount of steam heating area, need to use to determine the tonnage of the boiler. WNS and SZS different models, provided with a vapor pressure hot water temperature is also very different. Make sure to choose to use that does not waste as needed.
