Hebei Cangzhou issued a "special program on the implementation of standards of governance specification of high pressure water tube 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.
Today will talking about the challenges and problems of the circulating fluidized bed (CFB) combustion technology are summarized and analyzed. In order to resolve the problems inCFB boilerapplication,designprincipals and method ofCFBboilerwith the low bed inventory is proposed by ZGBoiler, cooperated with Tsinghua University. And a full set ofdesigncode of newCFBboilerwith low bed inventory has been developed, todesignthe product structure of new generationCFBboilers.
What are the reasons of the accident with a food factory steam specification of high pressure water tube boiler steam boiler plant a food causes of the accident which causes food plant accident with a steam boiler has what? The use of safe steam boiler is very important, if used improperly, the operation is not standard, it is very simple cause significant losses, the worst case will touch the lives of so for the use of a steam boiler users who demand a careful understanding of the causes steam boiler attack the cause of trouble. 1. Priming: The jobs in the job process steam boiler, the boiler if poor water quality and perhaps higher salinity water, the boiler load is added too quickly, causing priming phenomenon, its main features are: water level vigorously shaken onset of water gauge, water in the boiler onset bubbles, the steam temperature drops, leading to the onset of severe water impact when the club pipe. So it will make the steam boiler was bound to affect perhaps damage, so if the boiler presents Priming phenomenon, we must strengthen the handling of water quality, and sewage operations. 2. The blast furnace tube attack is the primary cause of tube corrosion due to poor water quality and perhaps the formation of fouling, boiler water can lead to burst pipes, others may be due to the shortcomings of planning, lack of information on the strength and weld quality is not good, will cause seizures burst pipe incidents when the attack blast furnace tube will be accompanied by significant blasting sound, the sound of a jet, with the water level and pressure significantly their homes, while if the situation presented to the right were immediate shutdown operation.
What is the most important in the 21st century? Of course, people are the most important. ZG specification of high pressure water tube boiler has a first-class technical engineer team, a first-class service sales team, 360 high- and mid-level R&D technicians and more than 140 service teams, aiming to provide customers with a comprehensive, three-dimensional customer experience.
