Type: SZL29-1.6 / 130 / 70-AII bulk water pipe 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: 130oC 6) 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 9,800 12) Boiler heating area: a) Radiation: 164.1m2 b) Convection: 490m2 c) Coal economizer: 595m2 d) Air pre-heater: 367.34m2 13) The smoke emission temperature of the coal economizer exit: 200oC 14) The original dust discharge concentration: 1,662.25mg/m3 15) S02 discharge concentration: 450mg/m3 Features: 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
