By analysing the combustion characteristics of anthracite Ⅱ produced in Fu-jian,the authors conclude that the key to the improvement of heat efficiency of an-thracite Ⅱ burned in a circulating fluidized-bed boiler is to prolong the residence time ofthe fine particles of the fuel.

This paper introduces the design principle, characteristics, application field of the heat & steam coproduction fluidizedbed boiler and its operation situation.

A New-type Purifier for Removing Smoke dust Trom Tluidized Boiler;

Study on anti-wear and anti-corrosion of buried pipes in an ebullition boiler;

The influencing factors of wear of buried pipes in ebullition boiler are analyzed,and the anti-wear measures are put forward.

This text primarily introduces the necessity of choosing the optimum smoke flow speed to boiling boiler continous and economic o peration and also simply analyzes the mechanism of how to prevent the ash from h eated area.

Under conditions of different wind velocity of boiling boiler, appearing fix ed bed,boiling bed and pneumatic transportation three kinds of states and severa l unusual boiling phenomenon are introduced.
