“…Another major constraint in the commercial briquetting of biomass is within the context of supply chain management-the sustainable supply of biomass resource at cost-effective price and volume. This is influenced by a number of factors, including biomass structure, seasonal harvest, and the scattered geographical distribution of biomass that makes it difficult for their collection, transportation, and storage on a large scale [23]. The design of an efficient and effective biomass supply chain thus becomes critical in facilitating sustainable raw material preprocessing and supply for commercial briquetting [24,25].…”

“…This is mainly due to the benefits it potentially offers including driving rural bio-economic activities (such as establishing new markets, creating new job opportunities, etc. ), environmental benefits (carbon neutrality, and improved waste management), and increased energy independence [23,152]. Further, it leads to improved use of locally available biomass resources, thus contributing to better and sustainable living condition [153].…”

“…Most of the heating energy needs of rural people are met by the direct burning of wood and other loose biomass in three-stone fire and other low-efficiency stoves. The limited production and use of briquettes could be linked to a lack of developed supply chain structure for biomass in both agricultural and forestry-related industries [23,154]. An efficient and structurally developed supply chain is essential in providing appropriate biomass in a sustainable manner for the production and development of markets for biomass briquettes.…”

The adverse effect of the use of fossil fuels on the environment and public health has given rise to a sustained renewable energy research and development. An important component of global renewable energy mix is the use of loose biomass, including agricultural and forestry residues, to produce solid fuels in the form of briquettes. Briquettes play a significant role in bioenergy mix in developing and developed countries. The production of biomass briquettes often entails the collection, transportation, storage, processing, and compaction of loose biomass that meet specific quality parameters. The densification process often involves the addition of binders to improve the cohesive strength of the briquette material. This paper surveys recent literature from 2012 to 2021 to establish the current state of research on the use of binders in briquette production; and reviews current parameters used in assessing the quality of biomass briquettes with focus on mechanical and handling properties. While a number of quality parameters were identified, their assessment methodologies varied widely in the literature, thus necessitating standardization for comparability purposes. The review also includes factors affecting the wide production and adoption of biomass briquettes in most developing economies and proposes ways of overcoming the bottlenecks.

“…The content of the beacon frame includes information such as the network number of the network and the communication channel occupied by the network. The control center obtains the corresponding network number and channel information according to the received beacon frames of different networks, and selects the appropriate network number and communication channel to establish a new wireless sensor network [11].…”

Current centralized heating monitoring system has realized the collection and control of working condition data in heating power stations, but there are still some shortcomings, such as the inability to collect data on the working conditions of user sides, and the inability to meet the further demand of heating enterprises for the refinement of heating network monitoring data. A wireless sensor network is a fully distributed sensor system with no central node, which can intensively deploy many sensor nodes to monitoring area through random placement, and integrates sensors, data processing and communication modules to form a self-organized network system. Therefore, in order to realize the intelligence of heating system and improve the flexibility of node data collection, the monitoring system can use wireless sensor network technology to realize wireless collection of node data, and display the collected data on a man-machine interface in real time. On the basis of research results from previous scholars, this paper expounds the research status and significance of centralized heating monitoring system design, elaborates the development background, current status and future challenges of wireless sensor network technology, introduces the methods and principles of wireless network communication protocol and heating and heat balance flow analysis, proposes a structural model of a centralized heating monitoring system based on wireless sensor networks, carries out the design of perception and convergence nodes, analyzes the layout of wireless sensor networks, explores the design scheme of centralized heating monitoring system based on wireless sensor networks, conducts the hardware and software design of the monitoring system, implements the software testing and hardware debugging of the centralized heating monitoring system, and finally discusses the relationship between data transfer related tasks and task scheduling. The study results show that the application of the centralized heating monitoring system based on the wireless sensor networks can not only more conveniently monitor, control and manage the entire heating networks, but also make full use of the centralized monitoring and quantitative management functions of the wireless sensor networks. This achieves dynamic tracking and monitoring of heating operation, real-time diagnosis of hidden dangers in heating operation, and safe, normal and energy-saving operation of the centralized heating system. The study results of this paper provide a reference for further researches on the design of centralized heating monitoring system based on wireless sensor networks.

The traditional widely used Chinese Kang heating system has been gradually becoming obsolete, due to the coal or wood burning emission that causes poor indoor air quality. In the interest to preserve the rural life, this study evaluated the performance of a retrofitted traditional Kang heating system with the use of alternative clean energy in a rural-dwelling in Xi'an, China. An air source heat pump (ASHP) was applied to drive the heating bed system, and an indoor stack effect tunnel was incorporated to induce the stack effect and to enhance the heating efficiency. A series of experiments were carried out by varying the exhaust tunnel height and heating mode. The system was shown to have produced significant improvement of the indoor air temperature and satisfied the Chinese standard, GB/T 50824–2013 for rural buildings. For the same mean outdoor temperature, when the stack effect tunnel height was extended from 1.0 m to 1.5 m, a 9.3% improvement in the heat release was obtained. When the heating mode changes from a single flue bottom surface heating to the combined flue bottom and vertical tunnel's lateral surface heating, the enhancement was 43.9%. The system would provide a sustainable way to renovate, upgrade and preserve the traditional Kang system with a use of a cleaner energy source.
