介绍了一种循环流化床锅炉热风系统的设计,该系统的热源为一燃用玉米芯的循环流化床热水锅炉,燃料燃烧产生的热首先产生热水,热水在换热器内与空气换热,然后产生43℃热风.这套系统设计关键为锅炉的燃烧温度选择、灰渣质量平衡以及如何保证热风风温稳定等.为进行这套系统的设计,通过试验研究了玉米芯在流化床内的燃烧特性、灰渣结焦特性以及循环床回料器的回料特性.在试验基础上,设计了这套热风系统,这套热风系统由锅炉、换热器、调节系统、除尘器等组成.首台采用该技术的热风系统已在山东登海先锋种业公司投产.这套系统可作为设计燃用稻壳、秸秆等其他生物质燃料锅炉的参考. 相似文献

This study describes the prospects for solar hot water systems in Vietnam. Changes in domestic energy consumption, both in terms of quantity and patterns of usage, particularly the increase in electricity use for hot water systems, are expected. VIETSIM, a computer program for simulating solar hot water systems in Vietnam will be described. This program has been validated by comparing the results of this program with those from the well-known TRNSYS program and shown to be highly reliable. The feasibility of SHWS will be studied for both the domestic and commercial sectors. For the domestic sector, the feasibility of SHWS will be studied for medium size families in three locations, representing the main climatic types in this country. The optimum criteria for designing SHWS in this sector are also investigated. For the commercial sector, a case of a hotel/office building is analysed and it is shown that the application of SHWS is very feasible due to high electricity prices for the commercial sector. With the natural advantages of high solar intensity, the social advantages of having plentiful and cheap human resources, and an economic environment with high energy and capital inflation, the use of solar hot water systems in this country can be very favourable if the government has the correct policies to encourage this application. 相似文献

A suitable operational strategy for a power interchange operation using multiple residential solid oxide fuel cell (SOFC) cogeneration systems for saving energy is investigated by an optimization approach based on mixed-integer linear programming. In this power interchange operation, electricity generated by residential SOFC cogeneration systems is shared among households in a housing complex without allowing a reverse power flow to a commercial electric power system in order to increase electric load factors of the system. For an SOFC cogeneration system operated continuously with the minimum output, two types of operational strategies for the power interchange operation are adopted: an operation to meet the total demand for electricity in intended households by the electricity output of SOFC cogeneration systems and an operation to meet the demand for hot water in each household by the hot water output of the SOFC cogeneration system. To clarify a theoretical limit of the energy-saving effects of the two strategies, this study numerically analyzes optimal operation patterns for 20 households on three representative days. The results show that the former operational strategy, which takes advantage of the high electricity generating efficiency of the SOFC, is more suitable for saving energy as compared to the latter strategy. 相似文献
