In the winter, heating has become a topic of great concern. Last year, coal heating in Beijing, Tianjin, Hebei, Shanxi, and Henan was severely restricted. So many people began to turn to natural gas heating and electric heating. In addition to these common ways of heating, there is also a way to warm up in the countryside, that is, the biomass is clean and warm.
Recently, the villagers of Chennian Town, Huimin County, Shandong Province received a red stove. From the appearance point of view, this stove and the coal-fired boiler at the same time have no difference. They are all connected with a chimney, and a kettle can be used to boil water. Although the appearance is still grounded, this red stove has a professional and mouthwash name - biomass heating stove.
Why are you calling this name? This is mainly related to the fuel burned by the furnace. The fuel burned by the biomass heating furnace is called biomass fuel. To put it plainly, it is the common agricultural and forestry waste such as straw, sawdust, bagasse, and rice bran. Direct burning of these agricultural and forestry wastes is environmentally damaging and illegal. But with a little processing, these highly polluting fuels will soon become low-carbon and environmentally friendly.
The processing flow of biomass fuel mainly includes grinding, impurity removal, screening, mixing, extrusion, drying and cooling. Since the preparation of biomass fuel has high requirements on the moisture content of raw materials, the impurity removal and drying thereof the dry link is especially important. Processed agricultural and forestry waste no longer contains heat-generating debris, so there is no pollutants when burned. In addition, the fuel does not contain moisture and is very dry, so the heat is also very large. Not only that, but also the ash after combustion of biomass fuel is very small. The burnt ash is still a high-quality organic potash with high grade and can be recycled. Because of these qualities, biomass fuels have become one of the representatives of clean fuels.
The surface of the shaped biomass fuel looks a lot like a feed and one grain. Due to the complexity of the biomass fuel processing process, the price is not low, the price is about 800 to 900 yuan per ton, and there are about 200 to 400 pieces per ton used by ordinary rural households. In the past two years, in order to allow more rural people to accept biomass fuel, many places have subsidized households that use biomass stoves. For example, in the old town of Chen Town, in addition to a red stove, the villagers also received a fuel subsidy of 600 yuan per ton. According to the calculation of a two-ton meter, this winter, the heating fee is about 400 yuan, which is very cost-effective. .
In addition to biomass fuels, in recent years, there is a supporting biomass burner in various places. In fact, as early as 2007, a company in Beijing introduced a full-featured biomass burner. The heat generated by this burner not only provides liquefied stoves for cooking for farmers, but also provides heating for heating. Warm air, and the auxiliary heat required for solar water heaters. Coincidentally, in 2014, some rural areas in Liaoning have also installed multi-functional biomass burners. This burner is hung on the wall, and the heat generated is not only warm, but also used for cooking. In the winter, when the burner is turned on, the room temperature in the rural areas of Northeast China can rise to about 20 °C in just 15 minutes.
However, until now, these environmentally friendly and easy-to-use biomass heating equipment are still difficult to achieve market-oriented production. Some people even think this is a loss-making industry. Among them, there are reasons for the lack of publicity, and there are also problems in the industry itself. First of all, whether it is biomass fuel or biomass heating equipment, the current domestic market products are mixed, and some inferior brands not only affect the villagers' experience, but also have a series of security risks. Not only that, at present, there is a lack of scientific evaluation standards for biomass fuels, which leads to distrust and disapproval of biomass fuels in some areas. Finally, there are also problems in the storage of biomass fuels. If the fuel is degraded during storage, it may not work or even cause damage to the furnace.
Despite this, in the eyes of many experts and scholars, biomass heating equipment still has great potential in rural areas. According to a data provided by the National Renewable Energy Center, by 2020, China's biomass resources can reach 264 million tons of standard coal, and the biomass heating potential reaches 130 million tons of standard coal. At least, from the perspective of resource supply, there is still a lot of room for excavation in China's biomass heating.
