2019 newest gas boiler

You must know the 2019 newest 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.

Gas-fired steam 2019 newest boiler abnormal situation, how should we deal with it? When we use gas steam boiler, failure or abnormal phenomena it is inevitable, but in order not to affect the normal use, in the event of a problem gas steam boiler to be timely processing solutions, then the face of all kinds of circumstances, we should how to handle it? Share some of the ways we deal with unusual circumstances. If only gas steam boiler circulating pump abnormalities, such as its current decreases, the pump outlet pressure back to zero, which indicates no oil pump is idle, it may be caused by oil vaporization. Yang identify the reasons therefore first vaporized measures; such as clogging of the filter circulating pump bypass opening evacuated immediately clean the filter; heat transfer fluid as a result of added aqueous or decomposed gases are not excluded in the system, should immediately open the vent an exhaust valve. Circulation pump pressure constant, the current increases and the flow drops, deterioration of the thermally conductive fluid, the viscosity increased, should be replaced or regenerated. New heat transfer fluid as a result of decomposition of aqueous or excluded gases in the system, should immediately open the vent valve of the exhaust gas. When the current is lower than normal circulation pump, the circulation pump efficiency is decreased, the flow rate decline may be heating pipes plug fouling, stainless steel chain should be cleaned. If the gas steam boiler before and after the filter increased in pressure, the pump inlet pressure drops, the filter may be stuck, the opening of the bypass, disassemble and clean the filter. In addition to its low furnace outlet temperature liquid phase heat carrier, mainly for lack of heat fouling problems, it is timely soot blowing. Gas steam boiler grate more common problem is stuck, there are reasons including breaking grate or the grate off loose pins; coal grate has stuck to metallic inclusions; arched grate; slag is sinking the tip of the grate stuck. In response to this phenomenon, the required reverse hand grate plate debris removal, replacement breaking grate after the start, then jammed as startup, stop the rotation of the reasons detailed inspection to resolve. But also to re-adjust the adjustment screw on both sides of the grate tension, if still does not work, we need to replace the sprocket.

Low nitrogen 2019 newest boiler and classification of meaning: In recent years, the state vigorously promote clean air plan, Yajian coal. Whether the use of coal-fired central heating boilers, and rural small coal stove for cooking and heating, are gradually being clean energy alternatives under the relevant policy. Thus, in recent years, sulfur dioxide, dust content in the atmosphere continues to decline. But it is worth noting that more and more use of natural gas, also caused a certain amount of nitrogen oxide pollution. Use low nitrogen boiler of the environmental benefits of very large.

As far as we understand fast 2019 newest boiler, Qinhuangdao City, Hebei Province to respond positively to tackling air pollution control actions, and intensive phase-out of coal-fired boilers. May 22, Qinhuangdao City Funing District launched the first action, a paper mill for a six tons of coal-fired steam boiler on-site demolition work. By Comrade Sun Guosheng, deputy director attended the action, and announced that coal-fired boiler central demolitions began.

Party Secretary Sun Zhichuan, Wang Hua district leaders to direct the demolition work, the Municipal Bureau of ecological environment, the ecological environment Branch area, technology and industrial Information Bureau, staying Town, elm Town, the next village management area, Funing town and other relevant units attended centralized demolition action.

The demolition operation was eliminated Qinhuangdao unified action to ban coal-fired boilers, Funing District is the city's main venue for the implementation of this action. 2019 coal-fired boilers area demolished 33 sets of objectives and tasks is that this concentrated action demolish 14 units, 12 sets of new coal-fired boiler investigation, a total of 26 sets of 248 tons of steam coal use is expected to reduce the amount of 149,444 tons, 145.73 tons of sulfur dioxide reduction , 439.37 tons of nitrogen oxides, soot 37.36 tons.
