In the game, she had five hurdles will stand out from the province's 18 cities 45 contestants, good access to the provincial tournament eighth-place finish.

Vertical steam boiler introduce vertical steam boiler Products: vertical steam boiler, all kinds of domestic furnaces comprehensive technical improvements, absorb the international advanced technology and the introduction of the new generation of horizontal fuel (gas) boilers, the product has been designed applied for the patent, the boiler head boiler shell, boiler shell, U-rings, furnace, furnace head, transverse pipes, tubes cupola. Combustion boiler using conventional techniques, from the media into the door hole, in the upper combustion grate, the flue gas was washed repeatedly laterally staggered in the cross-pipe furnace, in the flue gas containing fine dust particles and carbon black during the rise , multilayered tube is blocked, reducing the speed of movement, again falls on the combustion grate, burn the fumes into the atmosphere through the chimney. Performance: the boiler furnace grate rests within an upper portion of the U-shaped scraps, the direct flame furnace, and flushing mounted within curved tube furnace; vertical bent tube boiler structural features are: furnace interior curved inner pipe, increase radiation heating area. However, due to large water-cooling degree furnace, the furnace temperature reduced accordingly, therefore, generally suitable for burning high quality coal. The increase in the furnace masonry bricks, to maintain a high temperature furnace burn less coal. Better water circulation, where the site has been washed flue gas cooling water, the whole structure, good elasticity. Features: use of double grate combustion section of the combustion chamber, heating up, fast boosting of unburnt gas through the secondary combustion, functions as combustion, smoke, dust effect. Bending the upper furnace tube arrangement convection heating region, disposed in the lower furnace grate tubes and radiation heating furnace area, structure of the furnace and the flue gas flow, reasonable layout, good heat transfer, the boiler reasonable design, simple structure operation, easy maintenance, small footprint, less investment in infrastructure, the company is one of small enterprises with steam, heating and other equipment ideal.

Introduce some common sense about the boiler 1, the critical speed of the circulating fluid bed boiler. Gas flow rate corresponding to the minimum fluidization velocity or become known as the critical fluidization velocity. 2, the flow characteristics of circulating bed boiler? A high combustion efficiency of the fuel adaptability 2 3 4 desulfurization efficiency is low nitrogen oxide emissions high combustion intensity 5, 6 simply small cross-sectional area of ​​the furnace fuel and coal pretreatment system 7, a large load adjustment range, adjustment is easy to implement fast ash 8 utilization. 3, the partition circulating fluid bed boiler furnace and the corresponding characteristics into dense and dilute phases, a lower dense phase zone of the furnace, filled with hot materials, is a stable source of hot, heat storage is a thermal store , flow therethrough in an upper dilute phase zone of the furnace, the fuel air are required. 4, the positive balance calculation boiler efficiency, combustion of coal, boiler heat losses What? Coal particles is heated and dried: volatile combustion and precipitation: coal particles swell and rupture: re-cracking and coke burning carbon particles and wear. Heat loss 1 2 3 Chemical incomplete combustion loss of physical mechanical incomplete combustion heat of the loss heat loss 4 5 ash. 5, the charging cycle 4 Effect Effect Effect amount of the main factors affecting combustion in the boiler of a coal particle size distribution and particle 2 was 3 Effect fluidization velocity excess air factor 5 bed temperature Dense Phase 6 . 6, the basic form of the heat transfer in? In the heat transfer process, there are three basic ways of heat transfer: thermal and heat transfer, convective heat and radiant heat transfer. 7, their role in recycling and recycling processes? By the economizer feed water into the steam drum, a descending pipe into the water wall, by absorbing the heat released by the combustion of the fuel heating the water in the saturated steam passes through the heat absorbing further heat saturated steam into dry steam heating. 8, sewage, drainage pipe What? Sewer: blowdown drum door (left and right) turn on the water accident door, front door header sewage, sewage tank after the door, left the door header sewage and right door header sewage, sewage water jacket door (about) Dipleg sewage door. Drainage pipe: the low temperature superheater inlet header hydrophobic doors, front / rear desuperheater hydrophobic door header, the high-temperature superheater inlet / outlet header, the header hydrophobic dispensing door. 9, then what are pipe drum? Meter and accessories? Superheater, economizer recirculation duct, platoon expansion tube, a condenser tube, soot blower tube, economizer inlet pipe, the discharge pipe accident, centralized downcomer platoon expansion, a water level gauge, a thermometer, security door, pressure gauge, gas-water separator, header. 10, the cyclone structure and working principle? Cylindrical body, the central cylinder, a cone, a loop seal, the material returning leg, from the high temperature flue gas out of the furnace, two left and right into the two cyclones, increase after turning flue flue gas velocity in the cylinder the center of rotation of the form cylinder back down into the cone upwardly from the central cylinder wall Shuaixiang excluded smoke particles under high effort when the cone reaches the end coupled with its heavy fall below the loop seal. 11, Refeeder role? The ash from the circulation loop seal into the furnace combustion chamber 12, acting characteristics superheater? The use of flue gas heated to a certain pressure saturated steam superheated steam. 13, bag filter works and composition? Principle: inlet flue gas-containing flue dust particles into the lower caul plate over the flue dust reduction chamber, and then through the outlet to reduce the wind speed of the flue draft fan withdrawn via the discharge plenum chamber clean flue upper portion of the bag filter the atmospheric composition: inlet flue, the caul plate, the reduction of flue gas chamber, bag, net flue gas plenum chamber exit gas, ash silo, rotating ash blowing device, the air reservoir. 14, to the mounting position of the coal feeder, the number, composition mounted on the front wall of the furnace, the number of stage three consists of: a motor, a belt coal feeder, reducer, the motor slide. 15, the process of slag from the furnace down the three tap outlet derived by the discharge of slag, after water cooling to cool to a certain temperature onto the cooling belt-type transfusion Pa, and then transported by the inclined transport slag to the slag bin .

Most food processing facilities have industrial steam boilers or coal fired 1 mw hot water boiler prices for generating steam or hot water for processing, cooking, or sanitation. Coal, fuel oil, and natural gas are the major fossil fuels used by food industry boilers.
