Beijing New Energy Automobile Co., Ltd. is China's first to operate independently and gain new energy automobile production qualification of new energy auto companies, mainly engaged in new energy vehicles and key parts and components research and development, production, sales and service business segments, and the layout intelligent manufacturing, energy management, smart travel, Internet +, and other strategic emerging industries. In the new energy automobile manufacturing process, and a series of paint drying processes can not do without the help of hot water boiler. Due to the company before the device has reached less than the growing production needs, the introduction of the 2017 mid-tail electric company producing heating pressure hot water boiler (CEDR0.7--95 / 70-Ⅱ).

Hot water boiler which is not equipped with no impact can cause demineralizer 1, the waste fuel boiler fouling occurs, resulting in poor heat transfer performance of heating surface, so that heat generated by the combustion of the fuel can not be timely delivered to the boiler water, but a large amount of heat is smoke away, resulting in exhaust gas temperature is too high, if the exhaust gas loss increases the thermal efficiency of the boiler will be reduced. In order to maintain the nominal parameters of the boiler, fuel must be increased, thereby wasting fuel. About 1 millimeter scale waste fuel ten percent. 2, the heat receiving surface is damaged due to deterioration of the heat transfer performance, fuel combustion heat is not quickly transmitted to the boiler water, resulting in the furnace and the flue gas temperature. Thus, the temperature difference on both sides of the heating surface increases, the metal wall temperature, a decrease in strength. Under pressure pot, bags and even blasting will occur. 3. Reduce heat boiler output due to the deterioration of the performance of boilers, need to consume more fuel to reach the nominal rate of evaporation. However, with the increase in the scale thickness, the volume of the furnace becomes large, the fuel consumption is limited. Therefore, it is possible to reduce the output of the boiler. 4, the corrosion damage to the metal: oxygen in the water, acid, base materials will corrode the metal surface of the boiler, it is thinned, recess or perforation, thus reducing the power of the boiler, seriously affect the safe operation of the boiler. 5, in addition to improper operation Priming outside, when the boiler water contains more sodium chloride, sodium phosphate, and silicides oil, boiling or evaporation process boiler water, boiler water occurs when soap and organic base when Teng because soda will produce compost. Foam liquid surface, formed soda pool. No softening, easily scalable. Due to the continuous evaporation steam, boiler of calcium, magnesium, high impurity concentration is 30-50 times that of natural water, fouling rate beyond our imagination, only six months to a year, from 1-2 mm.

New coal fire late, often appear off the fire bed fire, fire away from coal gate about 0.6 ~ 1.Om, burning furnace is not strong, high ash carbon content. For existing furnace arch structural problems, from improving fuel fire conditions, improve furnace temperature begin to transform the boiler. After the furnace arch after the transformation, the people stove fuel from coal gate 0 · 3mRP fire, the fire bed combustion intense flame full of good, strong rotation. Since lowering the front arch, the arch extended, reduced to about 1 2 throat formed between the arch of the original pitch. Where the enhanced mixing flow disturbances, reorganized stream, enhanced combustion furnace, to effectively improve the temperature of the entire front region and the arch of the furnace, to reach 1400 degrees, the condition of the fuel to improve ignition. 2. The ignition point of coal in advance, the temperature of the furnace to improve the ash carbon content decreased. Smoke swirling mix and strengthen the separation of coke particles in the flue gas, so that it falls on the fire bed and the new layer further fuel burn. Flue gas also strong swirl in the flue gas CO, H2, CH4 and other combustible combustion gases, thereby improving the thermal efficiency of the boiler is more than 4%. But also improve the boiler output to meet the needs of the production of steam, reducing environmental pollution, expanding the scope to adapt varieties of coal.

First, when the flue temperature dropped to below 50 ℃ Solution: Check the tail may enter the flue if heated, while the flue thoroughly remove soot. No burning flue tail, can be re-started ignition; if burning, should be replaced, repaired burning member. Second, the combustion chamber when the negative pressure is too large Solution: When the exhaust gas temperature close to the temperature of the injected steam, or less than 150 deg.] C over 1 hour and stable, open the inspection hole inspection; after inspection after confirming the fire source, before start the fan ventilation. Third, shutdown or fire, air gun valve ajar solutions: reinforcing and electric 1050 kw steam boiler feed water drainage, or open the valve economizer recirculation tube to protect the economizer is not burning. Fourth, Kai, during shutdown lower furnace temperature, a solution of unburned fuel in the furnace: extinguishing device immediately put into vapor, carbon dioxide or other devices off fire. Five burning improperly adjusted, with insufficient wind or with the wind unreasonable Solution: Close the flue duct and baffle around the door opening, start sending prohibited, induced draft fan. These are the methods of electric heating steam boiler fast boiler to provide you with the handling of soot in the chimney, if you use electric steam boilers, with more than five can control their own boiler equipment need to be cleared up the flue, and select the appropriate method .
