本文介绍了工业型煤炉前成型的基本原理与特点;分析了影响成型特性的因素,如煤种、粒度、水分、成型压力和成型率等。通过燃烧试验,研究了炉前成型煤的层燃特性:通风均匀性、炉温水平、烟气成分、燃烬程度。试验研究与工业应用结果表明:炉前成型层燃技术是一种具有节能和环保双重效益的新技术。 This paper introduces the basic principles and characteristics of the industrial coal before forming; analyzes the factors that affect the forming characteristics, such as coal type, particle size, moisture, forming pressure and molding rate. Through the combustion test, the stomatal characteristics of coal before molding were studied: uniformity of ventilation, temperature level, composition of flue gas and degree of burning ash. Experimental research and industrial application results show that the pre-combustion layer combustion technology is a new technology with double benefits of energy saving and environmental protection.
