摘　　要：介绍了 2 .8MW错动炉排热水锅炉的研制过程和经验 ,同时介绍了两项专利技术 :错动炉排及套管式对流受热面 ,在小型供暖锅炉方面又提供了一种新产品。该型锅炉特点是组装式结构 ,套管式对流受热面节省 1/ 3空间 ,辐射受热面为自然循环 ,运行安全可靠、锅炉热效率高及出力足 ,可燃用低热值贫煤。The development process and experience of a 2.8 MW hot-water boiler equipped with staggered grates is described along with the presentation of two items of patented technology, namely staggered grates and cashing-pipe convection heating surfaces. A new product among small-sized heating boilers, the recommended boiler features a packaged construction. The casing-pipe type convection heating surfaces can bring about a 1/3 economy in space requirements. A safe and reliable operation of the boiler is secured by the use of natural circulation-based radiation heating surfaces. The boiler with a high thermal efficiency and full steam output can operate on lean coal of low calorific value, formed coal and shell-like refuse.
