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.
Coal-fired steam hospital coal hot water fire tube boiler manufacturers oil requirements and whether the induced draft fan: fuel steam boiler in the boiler, we believe this a boiler will not feel strange, because the front, some of its articles related to getting to know and understand it, and not know about it yet. So the following, in order to promote familiarity with all of the following, will continue to explain knowledge in this area, in order to have the learning effect. 1.20 tons of coal-fired steam boiler, the standard amount of coal every day, about how much is? 20 tons of coal-fired steam boiler, which is the standard amount of coal every day, and if, the calculation explanation, then, is the need to know the specific values, so in order to give a specific value, such as: rated steam pressure of the boiler, is is 1MPa, the water temperature is 20 ℃, the thermal efficiency of the boiler is 90%, in addition, the standard coal heating value is 7000 kcal / kg, then 24 hours a day if the full load operation, then, with its daily the amount of coal is about 50-56 tons. However, in practice, due to some unavoidable factors, it will lead to its value, and larger than 56.
6 tph WNS condensing gas-fired fire tube hospital coal hot water fire tube boiler manufacturers project for chemical industrySichuan New Torch Chemical Co., Ltd. is mainly engaged in the research and development of hydrogen isotope products, providing safe, stable and high-quality products such as heavy water, deuterium generation reagents and high-purity hydrogen sulfide to the national defense cause. The production process of these chemical products is inseparable from the steam heat source provided by the boiler, which is one of the main power equipment on its production line.In the face of increasingly serious environmental pollution problems, China has continuously promoted the "coal to gas" policy. New Torch Chemical actively responded to environmental protection policies and decided to introduce steam boilers that use clean energy as fuel. After understanding the demand and actual working conditions of Sichuan New Torch, ZOZEN recommended WNS series condensing gas-fired steam boiler. This series of gas-fired boilers adopts the structure of single drum, vertical type and wet back, which is safe and reliable. The combustion chamber adopts a large-diameter corrugated furnace to ensure full combustion of the fuel. With the advanced low NOx burner, it is easy to achieve low emissions of NOx ≤ 30mg/m³. In addition, ZOZEN installed energy-saving equipment at the tail of the flue according to the actual working conditions, so that the boiler thermal efficiency is as high as 98% or more, which is 5% higher than the similar boiler system on the market. Besides, the packaged characteristic of the boiler greatly shorten the installation cycle and reduce the installation cost.
The pollution-free environmental benefit of hot water hospital coal hot water fire tube boiler manufacturers is obvious: renewable biomass energy is used as fuel to realize the sustainable utilization of energy. Adopting high temperature subsection combustion technology and low emission of NOX,SO2, dust in flue gas, it is the best substitute for fuel (gas) burner, electric heating and so on. Internal inspection and preparation of hot water boiler, inspection of furnace and flue, inspection of boiler accessories, inspection of automatic control system, inspection of ancillary equipment, inspection of combustion equipment, inspection of auxiliary heating surface, The hot water boiler must do some inspection before running, these checks are not to be underestimated, possibly because of our neglect Cause very serious consequences. Therefore, we must guard against micro, hot water boiler operation before careful inspection of the following items. Including boiler internal inspection and use preparation. The furnace and flue inspection, furnace and flue dust and debris should be cleared. Air duct and flue adjustment doors, gates shall be complete and tight, flexible switches, accurate opening and closing instructions. Boiler accessories inspection, check the safety accessories are intact; cock rotation flexible, easy to use; all kinds of instruments and control devices should be complete, good, clean. After the check has passed, the pressure gauge plug should be kept in working condition. Automatic control system inspection. Inspection of ancillary equipment. The combustion equipment is checked to check if the combustion device is in good condition; the mechanical transmission system, the coal conveying system and the ballast system are tested normally; the pressure degree of the safety spring of the speed regulating box should be appropriate and the lubrication is good; the gauge of the coal brake is correct. Eagle iron neat, intact, ballast board integrity, flexible movement. Check auxiliary heating surface to check whether auxiliary equipment (induced fan, blower, pump, etc.) coupling is firmly connected; triangular belt is properly tightened; lubricating oil should be good and adequate; cooling water is unobstructed. After inspection, install safety shield, test operation separately, and pay attention to the current of idling. Internal inspection and preparation of hot water boiler The inspection of furnace and flue, the inspection of boiler accessories, the inspection of automatic control system, the inspection of ancillary equipment, the inspection of combustion equipment, the inspection of auxiliary heating surface, and the inspection of hot water boilers must be made before running. These examinations are not negligible and may have very serious consequences as a result of our neglect.
