Condensing Type Gas Boiler

Condensing Type Gas Boiler

As fast condensing type boiler manufacturer specialized in the production of gas boilers and electric boilers, it has gone through 20 years of development history. The energy-producing gas boiler and then fully welded to the pre-expansion, and finally Expansion technology, both to prevent corrosion of the tube gap, but also enhance the welding strength; threaded pipe using a high heat transfer coefficient, heat strengthening effect on the spread , reduce exhaust gas temperature and improve the thermal efficiency of the boiler. With industry-leading gas boiler products and perfect after-sales service, fast boiler boiler by many users of gas acceptance and trust.

How fuel (gas) condensing type boiler stack height standards should be implemented as specified? Oil, gas boiler chimney of not less than 8 meters, the height of the boiler chimney by specific approval of environmental impact assessment documents OK. When there is a building within a radius of 200m from the new boiler room around the chimney, the chimney should be higher than the tallest building in more than 3m. "Boiler air pollutant emission standards" -GB13271-2014

Horizontal pressure steam condensing type boiler efficiency of a number of cases China basically making impressive work of coal to gas, horizontal steam boiler with a very large reduces dust infected, the same time emissions of nitrogen oxides and other dangerous gases It has been suppressed. Efficiency is a measure of horizontal steam boiler critical navigation, a good number of cases began to say together to study the topic under pressure horizontal steam boiler efficiency. Through the analysis of relevant departments, horizontal steam boiler heat loss from two important parts: the full value is not ideal combustion and exhaust heat waste. Reducing exhaust waste heat should be modified in the tail horizontal steam boiler flue gas heat reuse install, or a more leading boiler condensate recovery system. Full combustion values ​​are not substandard summarized: the traditional horizontal steam boiler selection ejector combustion engine, resulting in air-fuel ratio can not be flexibly adjusted. Many of the non-selected horizontal steam boiler burner blast automatic machines, air-fuel ratio does not lead to over several following cases: air-fuel ratio over the chance of the more important sub-2: An excessive gas stream, having a full cool air is excess heat acting , leading to increased energy use horizontal steam boiler, steam boiler efficiency horizontal weakened; when the airflow is not enough, will produce insufficient combustion, caused by horizontal steam boiler efficiency is reduced.

Hebei Cangzhou issued a "special program on the implementation of standards of governance condensing type 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.
