【摘要】：為了解架空炕與落地火炕升溫特性、熱效率等方面的特性,依據(jù)國家相關(guān)標(biāo)準(zhǔn),對甘肅省臨洮縣傳統(tǒng)落地火炕與2016年新推廣的架空炕進(jìn)行了熱性能的對比試驗,研究了炕面溫度分布、炕面升溫降溫速率、排放煙氣溫度、炕溫對室內(nèi)溫度的影響以及架空炕的節(jié)能減排等性能,研究結(jié)果表明:架空炕和落地火炕炕面平均升溫速率分別為2.2和0.9℃/h;煙氣熱量能被架空炕充分地吸收利用,架空炕煙氣排放平均溫度較落地火炕煙氣排放平均溫度低36.1℃;架空炕和落地火炕的熱效率分別為66.8%和37.1%,相比傳統(tǒng)炕架空炕節(jié)柴率達(dá)到45%;有架空炕和落地火炕室內(nèi)日平均溫度分別為12.6和10.8℃,架空炕對室內(nèi)有較好的增溫效果;與落地火坑相比,架空炕有明顯的節(jié)能減排效果,每鋪架空炕每年節(jié)省945 kg薪柴,減排CO21 069.17 kg,減排SO20.45 kg,減排NOx 1.01 kg,減排PM107.4 kg,減排PM2.5為6.8 kg,架空炕的推廣應(yīng)用對中國農(nóng)村節(jié)能減排具有重要意義。
[Abstract]:In order to understand the characteristics of heating up and thermal efficiency of aerial Kang and floor fire Kang, a comparative test of thermal performance between the traditional ground-fired Kang in Lintao County, Gansu Province, and the newly popularized aerial Kang in 2016 was carried out according to the relevant national standards. The temperature distribution of the Kang surface, the heating and cooling rate of the Kang surface, the flue gas temperature, the effect of the Kang temperature on the indoor temperature and the energy saving and emission reduction of the overhead Kang were studied. The results show that the average heating rates of the overhead Kang and the floor fire Kang are 2.2 鈩，
