针对油田缺少天然气的地区，由辽河油田设计院与浙江温岭燃烧设备厂共同研制的QYZ型燃油燃烧器，于1994年12月23日通过了辽河石油勘探局组织的技术鉴定。这种燃烧器适应于微正压炉膛的加热炉，且热强度高。与当前使用的燃烧器相比，炉效可提高3％至5％。在保持额定负荷的情况下
Aiming at the lack of natural gas in the oilfield, the QYZ type oil burner jointly developed by Liaohe Oilfield Design Institute and Zhejiang Wenling Combustion Equipment Factory passed the technical appraisal organized by Liaohe Oil Exploration Bureau on December 23, 1994. This burner adapts to a furnace with a slightly positive pressure and has a high thermal strength. The furnace efficiency can be increased by 3% to 5% compared to the burners currently in use. In the case of maintaining the rated load
