由中国农业工程研究设计院加工室设计,四川省夹江县茶机厂制造的一种立筒式全金属高效间接加热燃煤热风机研制成功,并于1986年10月由“全国烘干设备综合利用技术推广联络中心”主持通过了技术鉴定。这种新型热风机主要由立筒式燃烧炉、立筒式夹层换热器、助燃小风机和离心式通风机所组成,具有如下特点: 1.采用燃烧与换热为一体的立筒式结构,升温速度快,热效率高,结构紧凑,造价低。 2.间接式加热,无污染,可烧多种煤,应用范
Design by the China Agricultural Engineering Research and Design Institute processing room, a tea factory in Jiajiang County, Sichuan Province, a vertical tube all-metal efficient indirect heating coal-fired heater was successfully developed and in October 1986 by the “National Drying Equipment Comprehensive utilization of technology promotion contact center ”presided over the adoption of technical appraisal. The new type of hot air blower is mainly composed of vertical burners, vertical-type mezzanine heat exchangers, combustion-supporting small fans and centrifugal fans, and has the following features: 1. Adopting the vertical structure of combustion and heat exchange , Heating speed, high thermal efficiency, compact structure, low cost. Indirect heating, non-polluting, can burn a variety of coal, application range
