Recently, the Shuangyashan City, thoroughly implement the first meeting of the Central and the National Finance Committee, the province's environmental protection spirit of the General Assembly to further implement the "State Council on the issuance of winning the Battle of Blue Sky's three-year action plan" to do "atmosphere ten" task finishing verification and improve air quality living environment for the residents to protect the health of the people, combined with the actual situation, the specific "Shuangyashan City 2018 air pollution control implementation plan."

"Plan" focused on job content is to carry out comprehensive improvement of coal-fired boilers, effectively reduce coal pollution. Of built-up urban area shutdown, demolition, instead of using biomass fuel boiler inspection, investigation and comprehensive urban fringe areas built-up area if there is a new violation, missing, incomplete elimination of small coal-fired boilers, to eliminate incomplete, missing, "resurgence" boiler promptly dealt with severely, and formed out of work ledger, as planned phase-out. Existing "clear" action identified 28 small coal-fired boilers, before the end of September 2018, to phase out the "cleared" of work, and in strict accordance with the requirements "a furnace" during the establishment phase out the boiler archives for future reference. Planning the construction of central heating heat source, heat accelerate network construction and transformation progress, constantly expanding area of ​​central heating and central heating ratio; advancing coal to gas, coal to electricity and other clean energy alternatives, to promote industrial parks and industrial clusters concentrated heat source, steam source facilities.

Battle of blue sky and started "out of coal-fired boilers" special action to start the county (district) level urban built-up area of ​​10 steam tons / hour and coal-fired boiler, tea furnace, operating coal-fired kitchen stove and other facilities, grain storage coal drying equipment out of work. County (district) to co-ordinate well out of work, organized a special team completed a comprehensive investigation of the status quo area coal-fired boilers, establish a list out of coal-fired boilers, the production out of specific programs, and to work out the boiler out of subsidies. Before the end of the first to eliminate a large number of pollution levels, residents reacted strongly to the coal-fired facilities.

What are the advantages of vacuum hot water boiler price in the heating aspect?

Winter heating has been one of the most important projects in northern China, some of the longer residence time residential district heating boilers generally use pressure or pressure hot water boiler, but most of these boiler systems there are complex, high operating costs, easy scaling, seriously affect the oxidation corrosion and other defects, residential areas, it will bring a lot of adverse effects. In recent years, it is widely favored by vacuum hot water boiler heating industry, and due to its excellent safety performance and minimal footprint and other advantages, is very suitable for building a heat source.

2. boiler technology energy-saving measures (1) strengthen the technological transformation of inefficient boilers. Due to our limited economic base, not all older boilers have been updated. For updates not included in the scope, efficiency is not high but there are more defective boiler should strengthen technological innovation. Technological transformation of industrial boilers, should try to achieve a multi-effect of the change is necessary to improve the thermal efficiency to save fuel, but also to increase output, reduce pollution and achieve civilized production, but also to adapt to burning low quality coal. (2) boiler should make full use of frequency control technology. When selecting the boiler pump and fans, are considered certain margin in the rated load, so that in fact the boiler operation, the fan and the pump flow is less than the rated flow equipment, are required to be adjusted. Is adjusted by adjusting the throttle in the past, i.e., OFF or the throttle opening degree smaller Importers baffles, the flow rate is reduced, but not significantly reduced motor power. Frequency is reduced by the drive motor speed, the motor output power decreases. Frequency control for pumps and fans, general can save 30% to 40%, the investment can be recovered through two heating season, at the same time, due to the deceleration operation, reducing mechanical wear and extend bearing life, improved mechanical reliability sex. (3) the rational use of automatic control technology boiler. Boiler operation, automatic control can improve boiler efficiency, energy conservation. In recent years, automatic control technology and the rapid development of computer control, and more Sheung drum water level automatic control device, automatic control and computer control the combustion process in the oil and gas boilers more general application, for Stoker, some boiler monitoring the use of computer rooms, manual adjustment is also received good results. Boiler automatic control and computer monitoring instruments should be simple, practical principle. (4) promote the use of heat pipe heat exchanger. At present, the domestic part of the boiler flue gas temperature is too high, a large heat losses, reduces the thermal efficiency of the boiler. Can effectively heat pipe heat exchanger flue gas heat recovery boiler, the gas - liquid heat pipe heat exchanger is mounted in the boiler feedwater heating flue, significant energy saving effect, only one heating season investment can be recovered for a heat exchanger. (5) using the condensing heat recovery boiler technology. In conventional boilers, the exhaust gas temperature is generally 160 ~ 250 ℃, water vapor in the flue gas is still in a superheated state, it can not be condensed into liquid water and release latent heat of vaporization. As we all know, the thermal efficiency of the boiler low calorific value fuel is calculated, it does not consider heat loss in a high latent heat of vaporization of the fuel heating value. Thus the thermal efficiency of the conventional boiler generally only 87% to 91%. Waste heat recovery boiler is condensed, to which the exhaust gas temperature is reduced to 50 ~ 70 ℃, full recovery of the latent heat sensible heat of flue gas and water vapor to enhance the thermal efficiency, the condensed water can be recycled. (6) reasonable steam accumulator. The steam accumulator is an energy save type apparatus, steam accumulator principle is that when the boiler load is reduced, the excess steam is fed into the boiler the steam accumulator and the steam under a pressure becomes high pressure saturated water. When the heat load increases, the amount of evaporation in short supply when the boiler, reducing the pressure accumulator, i.e., the high-pressure saturated water is separated into a low pressure saturated steam and water vapor produced by the user for use. Steam accumulator fuel savings typically 5% to 15%. (7) The vacuum deaerator technology. Vacuum deaerator oxygen is an energy save type method. Currently, oxygen supply and drainage method use large industrial boiler thermal oxygen atmosphere. This method of heating water to boiling temperature should at atmospheric pressure, oxygen in the water to drain away. Thermal oxygen atmosphere has two shortcomings. First, the atmospheric pressure boiling temperature, consumes a lot of steam, the boiler to reduce the effective use of heat. A 10t / h boiler feed water heated from 60 deg.] C to 105 ℃, steam consumption about 0.7t / h. Second, because the temperature of the boiler feed water economizer to improve the average water temperature increase, reduce heat economizer temperature, exhaust gas temperature increases, heat losses increase. These two points are the thermal efficiency decreases. And when the vacuum deaerator, the degree of vacuum is maintained at 7.999kPa (60mmHg), as long as the water temperature is heated to 60 deg.] C can achieve the purpose of oxygen. This not only saves steam and reduces exhaust losses, thereby improving the thermal efficiency of the boiler. (8) boiler water treatment technology to promote imports. It is estimated that imports of internal boiler every knot 1mm of scale, the overall thermal efficiency of a decline of 3%, and imports affect the safe operation of the boiler, through effective water treatment technology and cleaning technology, imports of non-boiler scale operation.

Traditional industrial boilers difference is that the internal pressure of the vacuum boiler is less than the ambient pressure (vacuum food you can think of), mainly used for hot water output. This is because in the case of reduced pressure, the boiling point of water is also reduced, so that at low temperatures can be done quickly boil.
