Technical parameters:1) Specification: SZL29-1.6 / 130 / 70-AII bulk water pipe hot water boiler2) Rated heat supplying: 29mW3) Water discharge pressure: 1.6MPa4) Returned water temperature: 70oC5) Water discharge temperature: 130oC 6) Smoke emission temperature: 160oC7) Chain-grate area: 37.96m28) Total weight of the boiler mainframe metal: about 181MT9) Hot air temperature: 71oC10) Designed heat efficiency: 80.5%  11) Dimensions (L x W x H): 13,000 x 7,600 x 9,800 12) Boiler heating area:      a) Radiation: 164.1m2     b) Convection: 490m2     c) Coal economizer: 595m2     d) Air pre-heater: 367.34m213) The smoke emission temperature of the coal economizer exit: 200oC 14) The original dust discharge concentration: 1,662.25mg/m315) S02 discharge concentration: 450mg/m3Features:1) SZL29-1.6 / 130 / 70-AII hot water boiler is a double-drum vertically laid    natural cycle boiler. The water fed to the coal economizer enters in the    drum. The heating surface is with enough space and full contribution 2) The burning equipment is installed with single-layer squama chain-grate    manufactured by Liaoning Fangwadian Yongning Machinery Factory. The    chain-grate seems like squama as it is filled with a lot of bars.    Therefore, little coal will be leaked from the boiler, and both sides    of the boiler chain will be sealed tightly. The boiler chain can be    adjusted automatically, and can reduce Paya accidents. The chain-grate    can be installed and unloaded conveniently, making the examination    and reparation easier. The chain-grate can be replaced on the condition    of non-stop boiler. It is with good dust cleaning performance. The    container installed on two sides of the chain-grate is playing the role    of water-cooling iron with reliable anti-retarding function 3) Both sides of the boiler are with membrane water-cooling walls with    good sealing. The outer side uses light boiler wall, and the epiboly is    with dried coating protection plate. With elegant appearance, it will not    cause rust after long usage. It is reasonably isolated with the wall, so    that the gas flowing speed in the boiler can be controlled within 11    meters per second 4) The heating surface is designed with enough margins. The front wall,    back wall, left and right sides form the independent loop. The hearth    is enough height, or the water-cooling wall is with enough height, so    that there is enough cycle pressure. In order to make the water    circulation safe and reliable, jet device is installed. The large room of    the inner boiler is installed with jet device and water pipe. The entrance    area of the falling pipe is well insulated with hot water 5) The front water-cooling wall and the back water-cooling wall form the    front and back arches respectively. The front and back arches all adopt    fire-proof materials to reduce the surface heat absorption capacity to    form high temperature area, which is a kind of boiler arch with strong    radiation. With early ignition, there are strong high-temperature vortex    cavities under the front arch, and the burning is strong under the back    arch, so that the coal adaptability can be greatly enhanced 6) Speed adjusting cabinet with 3K structure involutes planet driving and    floating even-load framework with power diverging. The product is    equipped with electromagnetic adjustable-speed electrical machine    and controller to adjust the speed with hand. A wide range of speed    adjusting is available for convenient and reliable usage with reliable    over-load protection framework 7) To prevent the back inlet window from heating and ash erosion, the    exit of the heart is installed with ash congealed pipe
