Based on the demand of energy saving and environment protection, this paper presents the work principle ,configuration and the characteristic of condensing furnace,and describes the application prospects in heating with heat air.

Economical Evaluation of Retrofitting Natural Gas Fired Boiler into Condensing boiler;

Potential component of condensate from condensing boiler is analyzed in theoretic method.

Based on the heating characteristics of the solar energy heating in north of China, a heating system of condensing boiler assistant solar energy hot-water heating system was presented.

It introduces the structure of new built 3# FeMn blast furnace ball type hot blast stove in Xingang Ferroalloys Works, compared with internal combustion type hot blast stove, and analyzes its superiority in operation.

Describes the design characteristics of ball type hot blast stove for No.

A new front preheating process to get higher blast temperature on pebble stove was put forward according to low blast temperature and shortage of high heat value gas in Chinese iron and steel industry.

5 blast furnace, such as the bell-less BF top, slag granulating process, external-bay precipitator and pebble stove.

The pebble stove is applied in the overhaul of the air stove of GISE's No.
