错动炉排套管式节能热水锅炉_2_8MW_的研制

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、型煤及果壳类物料。

Research and Development of an Energy-saving Hot Water Boiler (2.8 MW) Equipped with Staggered Grates and Casing Pipes

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.
