Significance and measures of high efficiency boiler ecomfort pressure test: each boiler pressure test is to be done at the factory test, this step is mainly to check the boiler pressure tightness and withstand strength components, once the pressure test is failure is detected, the boiler must deal with immediately returned to the manufacturer, can no longer continue to sell to the user.

How to use the gas high efficiency boiler ecomfort cleaning device? How to use the gas boiler cleaning device? Gas boiler detergents suitable working pressure 13kg / cm ~ 2, less than the amount of evaporation 10t / h boiler without economizer and superheater, before use, at about 80 ℃ The detergent was dissolved in 20% strength hot aqueous solution. Gas hot water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. The boiler water is then visible to the lowest water level, and then the solution was injected into the furnace and melted to maintain a high level. Then lit, heated, put the stove to boil. Furnace operation can be divided into two ways: and atmospheric pressure. When atmospheric pressure boiling, when the stove boiling water, boil over low heat to maintain boiler water. After the pressure in the furnace was increased to 1 kg / cm, for a period of time (less than 24 hours), and then under reduced pressure. After the cease-fire to boil, turn on the water to gradually pay, the oven temperature to slow down to prevent residual stress. Only when the boiler water temperature dropped to about 50 ℃, the water can be released.

Although the high efficiency boiler ecomfort body does not bear the pressure imposed by the ring pump, the boiler always bears the hot water static pressure provided by the high water storage tank. The higher the floor, the higher the hot water static pressure. The diameter of exhaust tube installed on the body of atmospheric hot water boiler is too small, and some of the exhaust pipe diameter is only 20 mm, so the steam produced in the boiler can not be discharged quickly, which makes the boiler body bear a certain pressure and there is a certain danger. It is found that when the rated power of an atmospheric hot water boiler is 300000 kcal and the exhaust pipe on the body is 20mm, the boiler will be produced due to the lack of discharge capacity. The steam pressure of 0.15 MPA. The greater the rated thermal power of the boiler, the greater the steam pressure in the furnace and the greater the danger. The atmospheric hot water boiler is changed into a steam boiler, that is, the exhaust pipe connected with the atmosphere on the boiler body is installed directly on the steam device, and the control valve is installed on the exhaust pipe. Others install control valves on the exhaust tube, directly from the boiler to take boiling water or hot water bath, this is extremely unsafe. If the boiler turns off the control valve in operation, under the condition of increasing pressure, the normal pressure hot water boiler is very vulnerable to explosion, and the consequences are unthinkable. Turn the pot The exhaust pipe connected with the atmosphere on the furnace body is used as a return pipe, so that the boiler body is always in the state of full water pressure. This closed loop has two hazards: the first is that when the temperature of the furnace water is too high, the steam produced cannot be discharged, so the pressure will continue to rise, and the explosion and leakage accidents may occur at any time. The second is that even if the boiler water temperature is not high, it will not produce a large amount of steam, but because of the role of circulating pump, the boiler body bears high hot water circulation pressure.

Comprehensive reduce coal consumption, a few days ago, Baoding, Hebei Province issued a "blue sky Baoding win the Battle of three-year action plan" (hereinafter referred to as the "Program"), "plan" put forward specific solutions.

First, the heating pollution control

1, to reduce total coal consumption

Adopt an integrated coal reduction measures to reduce coal consumption. Reduction of new coal project alternatives. Complete bulk coal clean alternative area designated as a "ban on coal zone", in addition to electricity, central heating and raw coal coal-fired outside the "clear." Promote the use of clean coal, non-coal for electricity cuts, increase the proportion of electricity from coal. Enhance the proportion of clean energy, and actively develop renewable energy. Industrial Waste efficient alternatives such as coal and waste heat supply heat. Multi-channel expansion of natural gas supply, accelerate the construction of natural gas production, supply and storage sales system, develop non-fossil clean energy, give priority to renewable energy generation Internet, and actively carry out the heat, wind, solar and biomass energy use pilot projects. Encourage the development of biomass thermoelectric County have the resources to conditions of heat and power, biomass briquette boilers and scale natural gas chemical and biological substances. By taking measures to reduce coal comprehensive, complete province to decide Yajian coal consumption targets.

2, accelerate rural clean heating

To proceed from reality, should the electric power, gas should the gas, the coal should be coal, it should be hot is hot, the raised ring Beijing, the main city of Central City and other plain areas, rational distribution of science, science and progress targets set number of transformation to ensure the safety of the masses warm winter.

① heating diversified towns, villages conditional alternate embodiment of central heating.

② the completion of basic insurance North "ban on coal zone" and change to gas, electric construction of the main city, the main city ring accelerate dispersion of coal-fired and alternative Baonan key counties, and strive to three years to a total ban on the use of decentralized heating fuel Plains coal. "Substitution of gas for coal" adhere to the "gas will change" to ensure safe construction, safe use, security management, gas boiler energy efficiency of not less than level 2. The development of gas "pressure uninsured people" program, detailed list of contingency plans.

③ local conditions and actively promote photovoltaic solar, wind, biomass, geothermal heating mode, the implementation of solar heating pilot demonstration projects.

④ can not be implemented in rural mountainous areas clean heating transformation, and actively promote clean coal, and improve supply security system, the implementation of clean coal underpinning policy.

⑤ support agricultural production priority use of renewable energy, encourage the use of gas-generation coal, electricity generation of clean coal and other fuels such as coal generations, the phasing out of agricultural production in the plains with scattered coal-fired. 2019 basically completed the bulk of agricultural production of coal governance.

3, accelerate urban central heating

Promoting cogeneration heating energy structure, large-scale coal-fired boilers, geothermal energy, industrial waste heat as the main heat source, natural gas, electrical energy, biomass and other as complementary. Making full use of industrial waste heat, the conditions of the county to implement a city of a centralized heat source, synchronized planning and construction of central heating pipe network, and promote town extends to the surrounding heat source. Develop distributed heating gas boilers, electric boilers and other heat storage. Scientific and rational use of geothermal heating, into a film support regional development and utilization of geothermal heat pumps and the construction of gas distributed power station. Urban central heating can not cover all the villages in the implementation of clean energy alternatives.

4, strengthen the clean energy supply security

Establish a sound working mechanism of gas, emergency power supply security, oil and gas pipeline protection, on the basis of 2017 filled the gap on natural gas, natural gas plan focus on incremental substitution of gas for coal project in 2018, the 2018-2019 heating season to ensure that dual-generation project gas, electricity supply effectively improve the city's energy level security operation. Strengthen protection for air supply and power supply capacity, speed up the layout of the building and the city and county levels peaking gas storage facilities supply business, accelerate the improvement of the power grid and gas pipeline construction.

5, strengthen the bulk coal market and poor quality coal for control

According to sector regulation, local management, levels of responsibility and "who approved, who control", "who is in charge, who is the principle of supervision", strict bulk coal production, processing, storage, sale and use of corporate governance. Strengthen departmental interaction of law enforcement, strengthening the floor management to crack down on sales (including online sales) and use low-quality coal for violations. Strict control of industrial and civil coal quality, strict implementation of "coal quality coal for civilian goods" (GB34169-2017) standard, the quality of coal supplied to customers production and processing enterprises must meet the "industrial and domestic fuel coal" Hebei (DB13 / 2081-2014) local standards.

6, out of the transformation of coal-fired boilers to strengthen and deepen governance

Demolition firm covering central heating boilers scattered coal-fired in the area. The completion of the city 35 steam tons / hour and coal-fired boiler, stove and stove operating a small coal stove replace the task of transformation. Before the end of 2019, more than 35 tons of steam / h coal-fired boiler basically completed colored plume governance reform and ultra-low emissions, coal-fired boiler to retain the overall emission limits and achieve energy efficiency standards. Promote clean coal-fired boilers. A ban on new 35 steam tons / hour and coal-fired boilers. The main city and counties (cities, districts) ban on new built-up area 35 steam tons / hour and below a biomass boiler, more than 35 tons of steam / hour biomass boiler to achieve ultra-low emissions standards. Out central heating pipe network coverage and bulk coal fired boilers in the range, it does not have the area in cogeneration district heating conditions, and the like may principle of volume replacement, construction of large-capacity coal-fired central heating boilers alternative. Start the implementation of the transformation of low-nitrogen combustion gas boiler.

7, improve energy efficiency
