公司从1985年开始，在吸收借鉴前苏联、波兰、意大利、法国等国外技术基础上自主研发的煤气发生炉，命名为：D3.0-88型连续鼓风两段炉。1989年在上海矽钢片厂煤气站首次使用，1990年一次投产成功。项目通过了机电部、山东省科委、山东省经委组织的专家鉴定，设备在热效率、气化效率、环保指标等方面达到国内外同等产品先进水平。此后，两段煤气炉得到逐步完善，形成系列产品，成为煤制气市场的主力产品，在郑州白鸽公司、无锡恒亨白炭黑有限责任公司、沈阳沈西煤气站等多个项目中应用。

It is a gasifier independently developed by the company since 1985 by absorbing foreign technologies from the former Soviet Union, Poland, Italy and France, called D3.0-88 Two-Stage Continuous Gasifier. It was first used in the gas station of Shanghai Silicon Steel Sheet Factory in 1989 and successfully put into operation in 1990. The project passed the expert appraisal organized by the Ministry of Mechanical and Electrical Engineering, Shandong Science and Technology Commission and Shandong Economic Commission, and the equipment reached the advanced level of the same products at home and abroad in terms of thermal efficiency, gasification efficiency and environmental protection indicators. Since then, the two-stage gasifier has been gradually improved, forming a series of products and becoming the main product in the coal gas market, and being applied in many projects, such as Zhengzhou Baige Co., Ltd., Wuxi Hengheng Baitanhei Co., Ltd., Shenyang Shenxi gas station, etc.
