Energy Saving Fully Automatic Oil fired Steam Boiler for Industrial Use in Can Tho
Fuel oils burned in boilers include the heavier oil, diesel oil and others. As a liquid, fuel oils are relatively easy to handle and burn. In most oil boilers, the oil is atomized with air, steam, or pressure to enhance combustion. The characteristics of atomized oil approximate those of natural gas. The heating value of fuel oil is derived primarily from its two major constituents, hydrogen and carbon. Most fuel oils have a hydrogen content that ranges between 10 and 14%, and a carbon content that ranges between 86 and 90%.
After electric energy saving fully automatic fired steam boiler for industrial use in can tho shutdown, how to carry out maintenance in the long-term disabled electric steam boiler, furnace should pay great attention to external corrosion and maintenance problems. First, after power shutdown cooling steam boiler, the ash must be thoroughly cleaned and the heating surface fouling the upper grate, the lower portion of the furnace. Then to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. The quicklime as a drying agent, within the furnace or flue gas per cubic meter should be placed generally about 3kg. After placing all the ventilation should be tightly closed doors. After the change of lime powder to be replaced. Low-lying position as boiler room, ground during shutdown severe flood tide, often approach should be used and placed a small fire to dry desiccant combination. If the boiler shutdown a long time, after the complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace. As for anti-corrosion maintenance methods inside the furnace shutdown, the shutdown Yaoan the length of time to be. In general, no more than one month shutdown maintenance wet available, more than one month should be taken to maintain dry. To note the following problems when a dry maintenance: desiccant boiler not in direct contact with the metal surface, may be mounted in a container such as the iron plate after the desiccant is placed, and a hole for shutting the other hand hole cover, valve steam, the water pipe change must cut lime powder should be replaced.
As the "Star Pavilion" on the show, the arrival of fast boiler is attracted quite a stir. Guests and friends from all over the world friends are gathered in front of "fast Boiler" booth, feeling the charm to bring clean boiler. This is the third appearance in the fast side of the trade show, our booth set up in the middle of the field, in the light against the background, beautiful booth set off for the scene of different merchants brought extraordinary appeal.
Some knowledge boiler Introduction: boiler is an energy conversion device, the energy input to the boiler chemical energy, electrical energy, a boiler with a steam output of the fuel in the constant heat, high temperature water or organic heat carrier. Today introduced are several little knowledge about the boiler. 1, a way to improve the efficiency of the boiler A which:? ⑴ low heat losses: prevent heating surface fouling and coking, the rational use of the burner, controls the blower inlet air temperature, water temperature of attention to the impact, into the furnace to avoid excessive wind note impact milling system operation; ⑵ mechanical incomplete combustion to reduce heat loss: rationally adjust the fineness of pulverized coal, the excess air ratio control of appropriate, attention combustion adjustment; ⑶ quality assurance fired boilers; ⑷ reduce soda losses: guaranteed boiler quality water supply, installation and maintenance to improve the quality of the steam separator means, to maintain the operation of the boiler load, the water level, steam pressure and other parameters of stability, so that the boiler water separation apparatus operating under normal conditions; ⑸ index management adhere to the small boiler. ? What are the reasons boiler fire answer: ⑴ low boiler load, low temperature furnace, combustion temperature, combustion oil investment is not timely; ⑵ poor coal quality, low volatile matter, ash is too large; ⑶ air volume to adjust properly, once too high wind speed, wind powder imbalance, the excess air ratio is too large; ⑷ excessive negative pressure maintaining furnace; ⑸ bunker powder level is too low or fallen powder to the powder to make the powder unevenness; ⑸ large depression coke furnace, disturbances in the furnace is too large; ⑹ ash, coke playing time is too long, especially large caused by cold air leakage into the furnace temperature drops to a low load; ⑺ blast furnace tube, a large number of soft drinks into the furnace; ⑻ fire protection action; ⑼ device malfunction, such as sending, fan, tripping of mill, Auxiliary disappeared.
