Bulk Hot Water Boiler

Technical parameters: 1) Specification: SZL29-1.6 / 130 / 70-AII bulk water pipe hot water boiler 2) Rated heat supplying: 29mW 3) Water discharge pressure: 1.6MPa 4) Returned water temperature: 70oC 5) Water discharge temperature: 130oC6) Smoke emission temperature: 160oC 7) Chain-grate area: 37.96m2 8) Total weight of the boiler mainframe metal: about 181MT 9) Hot air temperature: 71oC 10) Designed heat efficiency: 80.5%11) Dimensions (L x W x H): 13,000 x 7,600 x 9,80012) Boiler heating area:a) Radiation: 164.1m2b) Convection: 490m2c) Coal economizer: 595m2d) Air pre-heater: 367.34m2 13) The smoke emission temperature of the coal economizer exit: 200oC14) The original dust discharge concentration: 1,662.25mg/m3 15) S02 discharge concentration: 450mg/m3Features: 1) SZL29-1.6 / 130 / 70-AII hot water boiler is a double-drum vertically laidnatural cycle boiler. The water fed to the coal economizer enters in thedrum. The heating surface is with enough space and full contribution2) The burning equipment is installed with single-layer squama chain-gratemanufactured by Liaoning Fangwadian Yongning Machinery Factory. Thechain-grate seems like squama as it is filled with a lot of bars.Therefore, little coal will be leaked from the boiler, and both sidesof the boiler chain will be sealed tightly. The boiler chain can beadjusted automatically, and can reduce Paya accidents. The chain-gratecan be installed and unloaded conveniently, making the examinationand reparation easier. The chain-grate can be replaced on the conditionof non-stop boiler. It is with good dust cleaning performance. Thecontainer installed on two sides of the chain-grate is playing the roleof water-cooling iron with reliable anti-retarding function3) Both sides of the boiler are with membrane water-cooling walls withgood sealing. The outer side uses light boiler wall, and the epiboly iswith dried coating protection plate. With elegant appearance, it will notcause rust after long usage. It is reasonably isolated with the wall, sothat the gas flowing speed in the boiler can be controlled within 11meters per second4) The heating surface is designed with enough margins. The front wall,back wall, left and right sides form the independent loop. The hearthis enough height, or the water-cooling wall is with enough height, sothat there is enough cycle pressure. In order to make the watercirculation safe and reliable, jet device is installed. The large room ofthe inner boiler is installed with jet device and water pipe. The entrancearea of the falling pipe is well insulated with hot water5) The front water-cooling wall and the back water-cooling wall form thefront and back arches respectively. The front and back arches all adoptfire-proof materials to reduce the surface heat absorption capacity toform high temperature area, which is a kind of boiler arch with strongradiation. With early ignition, there are strong high-temperature vortexcavities under the front arch, and the burning is strong under the backarch, so that the coal adaptability can be greatly enhanced6) Speed adjusting cabinet with 3K structure involutes planet driving andfloating even-load framework with power diverging. The product isequipped with electromagnetic adjustable-speed electrical machineand controller to adjust the speed with hand. A wide range of speedadjusting is available for convenient and reliable usage with reliableover-load protection framework7) To prevent the back inlet window from heating and ash erosion, theexit of the heart is installed with ash congealed pipe
