In the winter season, Fushun City, the town of Dongzhou District hada Liaoning Province, this ancient village is undergoing a transformation heating, core change is the use of "provinces" biomass best factory price fired steam condensing combi boiler.
Yao is the inventor in "provinces" biomass boiler. He said, "provinces" boiler, that is, to save money, labor, and material. Combustion and conventional combustion boiler essentially different, are in the normal combustion surface of the fuel from the outside and inside, top-down combustion, using a strong wind, or take pulverized fuel, and other physical and chemical techniques, cause the fuel in the shortest rapid combustion of the time. "Provinces" boiler contrary, starting from the bottom of the combustion of solid fuels, from the bottom up, a minimum amount of intake air by controlling the slow combustion. In 2013, the innovative energy-saving combustion technology obtained national patent, and Chinese Academy of Sciences Institute of Engineering Thermophysics, experts Tsinghua University, Tianjin University and Harbin Institute of Technology as "domestic initiative, the leading domestic" and suggested in our rural north conduct a comprehensive promotion.
Yao said in the last year, Dongzhou District not only invest in the construction of "provinces" biomass boilers, but also the laying of underground pipe network 3500 meters, central heating ancient village 30 farmers.
We understand that in 2016, Fushun City, has more than 600 households will be "provinces" boiler for the production and life. 2018, Fushun City, the ancient village of straw as a pilot village central heating, promoting the use of "provinces" boiler.
"With the gradual popularization of rural straw central heating, greenhouses can pick Heating, sustained economic heating greenhouses; straw waste form the commercial mode of operation into treasure, straw harvesting, transportation, storage, processing, a new farmers' income channels; the sky bluer, the water clearer, more green mountains, beautiful environment will inevitably become a new growth point of the rural economy but to embark on a modern intensive production, road projects of market-oriented operation, there is still a way to go. . "in Yao she said.
3 tons of gas chemical plant steam best factory price fired steam condensing combi boiler how much the price of gas chemical plant 3 tons of steam boiler price how much? For the chemical industry, for both the coal era or the early era are now inseparable from the gas steam boiler, so, for the procurement of chemical plant steam boiler must go through a wide range of contrast, this is the case, we need to chemical enterprises procurement staff for a detailed comparison between the various boiler plant. Recently, there is a chemical plant to fast boiler advice to purchase a 3 tons of gas steam boiler, hope fast boiler manufacturers here to help account for the price, there is a look at the tonnage of their choice is appropriate. In this regard, fast boiler for the actual situation of the chemical plant in understanding concluded that the need to use a chemical plant four tons of gas steam boiler. 3 tons is not the case now meet the production. After the chemical industry saw rapid technical personnel accounting data side, it is more recognized. The model is currently in the fast boiler price of around 50 million. So, for chemical plant three tons of gas steam boiler price has accumulated clear.
You must know the best factory price fired steam condensing combi boiler energy problems (induced draft fan power consumption rate, steam consumption) draft fan causes problems 1.1 boiler flue dust and fouling, in particular air preheater fouling, resulting in increased resistance to smoke duct . 1.2 boiler flue, tail heating surface and dust leakage. 1.3 Leakage Rate large air preheater. 1.4 furnace excess air coefficient is too large. 1.5 unit load changes, run the adjustment is not timely, resulting in furnace pressure is too large. 1.6 unit load or low frequent starts and stops. 1.7 coal into the furnace worse, from the design value. 1.8 low efficiency filter. 1.9 draft fan blade badly worn, low operating efficiency. 1.10 fan outlet flue gas desulfurization big resistance. 1.11 soda boiler pipes for leaks. 2, 2.1 to 2.1.1 operational measures to solve the problem of the strict implementation of soot blowing system to prevent the heated area ash, blocking ash, flue gas system to reduce resistance. 2.1.2 holding the induced draft fan, the flue gas separator baffles and dampers in the fully open position. 2.1.3 The experiment showed combustion boiler, proper control of excess air in the furnace. 2.1.4 adjustment chamber negative pressure, air leakage reduction furnace and the flue. 2.2 routine maintenance and testing 2.2.1 induced draft fan performance test to determine the optimum operating point and efficient workspace. 2.2.2 boiler, air preheater, a flue, ESP and other system leakage inspection, process. 2.2.3 timely check processing chassis, shaft seal leakage. 2.3C / D repair, eliminating defects 2.3.1 down strict accordance with movement clearance adjusting fan. 2.3.2 induced draft fan blade defect action elimination hand vane opening adjustment. 2.3.3 Importers and induced draft fan baffle opening check. 2.3.4 duct tightness check process. 2.3.5 wave plate replacement air preheater, rinsed sector plate gap adjustment. 2.3.6 eliminate dust defects and improve collection efficiency. 2.3.7 clean flue gas desulfurization system, flue resistance is reduced. 2.3.8 eliminate soda boiler pipe leakage defects. 2.4A / B repair and transformation 2.4.1 Check and repair the fan blades, replace seriously damaged blades if necessary. 2.4.2 for energy saving fan efficiency below 75%. 2.4.3 The fan motor frequency transformation. 2.4.4 of the precipitator, if necessary, transform and improve collection efficiency.
Water wall best factory price fired steam condensing combi boiler tube leak or burst phenomenon how to do 1, the normal water flow is not greater than the steam flow. 2, the furnace pressure transient and unstable prejudiced. 3, tube leak detection alarm device. 4, the furnace may not tight at the outward discharge gas and water vapor, and a significant leakage sound. 5, the main steam pressure drop. 6, boiler combustion dark flame instability caused by severe boiler fire. 7, when the induced draft fan is automatically cast, abnormal static vane opening is increased, the current increases. 1 reason, the presence of water wall tube material defects or post-production, the installation of the damaged pipe, poor welding quality. 2, the inner tube fouling overtemperature. 3, the inner tube corrosion. 4, water wall wear. 5, the long-term high load operation, furnace coking, coal sulfur corrosion caused by high temperature water wall. 6, improper combustion, flame deflection. 7, in the possession of bad foreign body, the water cycle. 8, the wall of the long-term over-temperature operation. 9, the temperature difference between waterwall tubes, mechanical stress crack. 10, the normal exit or drain sootblower steam punctured tube. 11, smashed chunks of coke furnace water wall tube or serious explosion occurred, resulting in water wall tube suffered external damage. 12, boiler overpressure long run. 13, the boiler starts to heat up, step-up too fast. 1 process, the leakage should try waterwall tubes outage. The leakage is not serious, while still capable of maintaining operation, note that each of the automatic operation when the device, if not normal, it is cut immediately to the manual, if necessary, may be down, down-load operation. Closely monitor the development trend of damaged parts, good accident anticipation, application shutdown as soon as possible. 2, if the leak is serious, the bursting point temperature after a sharp rise in quality work, leading to serious over-temperature wall, unable to maintain the normal operation of the boiler or threaten the safety equipment, emergency shutdown provision should be processed, when the steam temperature to protect the action value, the protection does not move, should immediately hand MFT. 3, note that the operation of the electrostatic precipitator, to strengthen the inspection checks, to prevent fouling, and the electrodes ESP hopper, pipes and the like plugging air preheater ash. 4, after the shutdown, should retain ID fan, the furnace pressure is maintained constant, there is no discharge to be stopped after soda ID fan.
