On the morning of August 18, Zhang Zengbo, a staff member of Hebei Daorong Solar Energy Company, went to debug and ignite the automatic biomass pellet heating stove for Luo Zhijun, a villager of Shahe Village, Qinhuangdao Development Zone. The stove automatically ignited after Zhang Zengbo put the long granular biomass-- the crushed, dried, and squeezed agricultural residues, such as branches and straws, into the stove, and there was no smoke or smell during the burning process.
Zhang Zengbo is trying out biomass heater at Luo Zhijun’s house.
“We have installed eight ‘solar thermal + biomass’ clean heating stoves, they are better than the traditional coal stoves, with automatic control ignition and shutdown functions, the fuel can be fully burned with more evenly heat, which is good for cooking.” Zhang Zengbo said.
Solar energy installations on villagers’ roof.
The “solar thermal + biomass” clean heating project is a new type of heating. The whole set of equipment is composed of solar collector tubes and a fully automated biomass heater. It is an upgraded solar energy installation. The temperature of the water tank can exceed 45 degrees with strong solar irradiance, and the house get warm with the solar heat. When the temperature of the water tank is low on cloudy days or at night, the biomass heating stove can automatically ignite and heat. Users can set the water temperature according to the heating area, and adjust the boiler to heat for winter, boiling water, and cooking. The cost is low, especially in sunny days. Users can also collect branches in exchange for biomass pellet fuel materials for free.
In order to avoid freezing of outdoor solar energy installations due to low temperature in winter, the thermal insulation pipes and heating cables on the equipment can help once it is frozen.
The clean heating in winter in rural areas is a major project for people’s livelihood and environment protection. In accordance with the requirements of the Clean Heating Plan for Qinhuangdao City in 2020 Winter, the rural “solar thermal + biomass” clean heating project has been implemented by the Urban and Rural Construction Bureau of the Development Zone.
Biomass fuel.
Wang Wen, deputy director of the Urban and Rural Construction Bureau of the Development Zone, said that there will be more than 1,400 families in 43 villages in the district to use the “solar thermal + biomass’’ clean heating method. The District Urban and Rural Construction Bureau is mainly responsible for project negotiation, bidding, and quality and safety supervision. In order to ensure the quality of the project, the bureau sends officials to inspect and supervise the installation work to coordinate with the clean heating offices and the sub-district offices.
At present, 168 families have installed solar collector tubes, and 28 families have installed biomass furnaces. It is expected that the installation of the “solar thermal + biomass” heating project will be completed by the end of September.
