湖南省煤炭科学研究所研制成功的83—4型两用节煤炉,是一种既能用于上点火又能用于下点火的先进高效煤炉。已于84年8月通过了技术鉴定: 该炉的设计结构和技术参数选择合理,经两批(90台用户)试烧反映和测试表明,它具有上火速度快、火力强、热效率高(57.13～59.64％)、封火效果好、使用维护方便、节煤效果显著等特点(比市售普通煤炉节煤25％以上)。该炉采用新研制的薄壁炉胆,具有先进水平。试烧用户反映,炉胆不易损坏;同
Hunan Institute of Coal Research 83-4-type dual-use coal-fired stove developed successfully is an advanced and efficient coal stove that can be used both for ignition and for ignition. In August 1984 passed the technical appraisal: The design of the furnace structure and technical parameters of choice, after two batches (90 users) test burn reflect and test shows that it has the ignition speed, firepower, high thermal efficiency ( 57.13 ~ 59.64%), good sealing effect, convenient use and maintenance, and remarkable coal saving effect (more than 25% coal saving compared with common coal stoves in the market). The furnace uses a newly developed thin-walled furnace, with advanced level. Test users reflect the burn, furnace is not easy to damage; with
