基于新型生物质柴灶的热水供暖系统应用

The Application of Hot Water Heating System Based on a New Type Biomass Stove

近年来,农村能耗问题成为人们日益关注的重点,作为北方居民生活中广泛使用的传统生物质柴灶的效率仍较低,且使用功能单一。对开发一种新型的农村用生物质热水循环柴灶进行介绍,并对其热性能进行测试。新型生物质柴灶在满足传统炊事用能的基础上,排烟热量进入火炕采暖之外,还可为室内散热器及地热盘管等散热末端提供热量,总体供热量可占燃料热值的57.9%。虽然其初投资是传统炉具的1倍左右,但其可大幅度降低煤炭消耗,与传统生物质柴灶相比其经济回收期仅为0.49年。新型生物质柴灶供暖系统的应用,大大提高了柴灶的热效率,减少能耗,降低了供暖成本,同时也改善了室内温度与热舒适度。

In recent years, the rural area energy consumption is drawing more and more attention. Compared with the low efficiency of traditional stoves, which are widely used in northern residents, a new type of rural biomass stove with hot water circulation was introduced in this paper. When the biomass is burning and satisfying the daily cooking demand, the new biomass stoves not only can provide high temperature exhaust gas to heat the Kang, but also provide some hot water for the terminal of heating supply, such as indoor radiators and coils. Based on the test results, the total heat quantity can account for 57.9 percent of the total low calorific value. Though the initial investment of the new type biomass stove was about twice of the traditional stoves, it can greatly reduce the coal consumption. Compared with the traditional stove, the economic payback period of the new biomass stove is only 0.49 year. Combined with hot water heating system, the thermal efficiency of biomass stoves were greatly increased. For the rural residences, the new biomass stove can reduce the energy consumption and heating costs. Meanwhile, the indoor air temperature and thermal comfort were improved effectively.
