燃油(气)注汽锅炉

燃油(气)注汽锅炉是用于稠油油田注蒸汽开发的新型蒸汽发生装备。该装置炉膛采用单回程(或多回程)蛇形管围成的水冷壁形式,吸收辐射热,尾部受热面采用光管和翅片管组合的水平蛇形管形式,吸收对流热;设计了炉外水水换热器,提高尾部受热面给水温度,解决尾部受热面露点腐蚀问题;发明了水平蛇形管受热面挡墙技术,解决了尾部受热面翅片管高温烧损问题,提高了锅炉整体吸热能力;发明了拱形回转烟道,解决了高温烟气回转室保温坍塌问题;研制了喷涂式保温专利技术,降低了锅炉外表温度。为解决较大吨位移动锅炉的运输超高问题,锅炉本体采用嵌入技术,降低锅炉整体的运输尺寸,满足运输要求。产品运行稳定,具有安全可靠、热效率高(与同类产品本体表面温度低20℃左右、与同类产品相比排烟温度低30℃左右)、环保效果好(污水零排放)等特点,满足了稠油油田采油工艺的需要。

Oil/Gas-fired Steam Generator

Oil/gas-fired steam generator is a new-type steam-generating equipment used for steam-injecting development at heavy oil fields. The combustion chamber of this equipment is in the form of single return （multi-return） coil-surrounded water- cooling wall for radiation heat absorption. The heating surface of the tail part adopts a combination of light pipes and finned tubes to absorb convection heat. The heat exchanger of boiler water is designed to raise feed water temperature of heating surface at the tail position and solve corrosion problem of heating surface dew point. The horizontal coil wall retaining-wall technology is invented to solve the bottleneck that high temperature causes damage of the finned tubes at the tail, thus improving heat-absorbing capacity of the boiler. The arch tube side flow deviation prevention technology is invented to prevent collapse of high-temperature flue gas returning chamber. The patent technology of insulation coating is developed to lower external surface temperature of boiler. To facilitate transportation of the large-scale boiler, the main body of the boiler adopts embedded technology to reduce the overall transportation size of the boiler to meet the requirements for movement. The product is stable in operation, reliable and safe, high in heat efficiency （the surface temperature of the main body is about 20~Clower as compared to the production of the same category）, and environmentally-friendly （no discharge of sewage）. It can satisfy the requirements on heavy oil production process.
