In biomass heating systems, the fuel is transported from the storage facility to the combustion chamber, where it is combusted. A fan is installed to improve the heat transfer and supply sufficient air for an optimal combustion. The flue gas from the combustion process passes through a heat exchanger and transfers its energy to water. A circulation pump transports the heated water through the distribution system. To reduce heat losses to the boiler room, the boiler and all pipes should be highly insulated. Some of the features of a modern biomass heating include: High fuel efficiency (80%–90%).Ultra-low emissions.Fully automatic operation (automatic ignition and shutdown, fuel supply, ash removal, heat exchanger cleaning).Very high operation and fire safety standards.Low fuel costs.

Oxyhydrogen gas is not limited for use in combustion engines and industrial applications. It can also be used for house heating purposes. Komitov et al (Komitov, Rasheva, and Binev 2019) determines the cost of building heating using different energy sources. It is summarized in (Table 6). It was concluded from the study that oxyhydrogen gas has potential to be used for heating purpose of building. From data in (Table 5), it is established that oxyhydrogen cheapest energy source for building heating. No hazardous emission is involved during oxyhydrogen combustion. It only cost water and necessary electricity for decomposition of water. Thus, oxyhydrogen is feasible for heating purpose of buildings but required a separate boiler room for electrolyzer and boiler chambers.
Spatial structure of Yangzhou’ s old public bathrooms: a space syntax analysis of the topological characteristics of their unique sensory space

The justified plan graph, essential syntactic values of typical cases, connectivity heat map of integration levels, and intelligibility chart of the four old public bathrooms of Yangzhou, in affiliation with thermal sensation experiences, are reported in Figures 17–21 and Table 3. The thermal sensation experience focuses on the “warm pool” room, “cool pool” room, main corridor that connects the “cool pool” to the “Tang Kou” room, and larger “Tang Kou” room or “Tang Kou” room in the special location. Spaces irrelevant to the thermal sensation experience are removed, including the entrance, secondary corridor, and boiler room.
Assessing the performance of a gas-water heat exchanger based on micro-heat pipe technology
Published in Experimental Heat Transfer, 2022
Yang Jingang, Wang Hao, Lv Jialu
The experimental system was carried out in a biomass boiler room, and the boiler produced the flue gas. The high-temperature flue gas flowed into the flue gas outlet end air duct after heat exchange and temperature reduction in FMHPGLHE through the flue gas inlet end air duct. The speed regulating fan provided different airflow speeds to control the flue gas inlet airspeed. The data acquisition instrument received the signal from the thermal resistance, transmitted the signal to the computer with the wind speed recorder, and displayed and recorded the temperature value.
