A coupling energy system of 10 clean-energy heating systems: A case study in Shandong province in China

A variety of clean-energy heating systems were applied in China with multiple energy systems complementing each other according to local conditions. The purposes are pushing forward a supply-side structural reformation; coordinating the utilization of waste heat in high energy-consuming enterprises; realizing the energy cascade use; improving the ecological environment. This paper introduces a coupling energy station of 10 new clean-energy heating systems located in the central city district in Jinan. It could make full use of renewable energy and ensure high-quality heating in winter, increase energy utilization efficiency, replace fossil fuels, and reduce primary energy consumption. Furthermore, it can make up for the deficiency of a single system and reduce the emissions from fossil fuels. After comparing the heating parameters, the authors got the conclusions that the heating area of this new energy system is equal to the traditional coal system burning 9,508.032 tons of standard coal, which means in each heating season, about 7,233.33 x 10(7) m(3) of waste gases, 45.64 tons of SO2 emissions, 69.586 tons of NOx emissions, and 139.52 tons of soot emissions will be avoided. So, this new energy heating system is safe, stable, energy-saving, environmentally friendly, and effective, which can completely replace the heating system of traditional coal-fired boilers.

Automated summary

The new energy heating system introduced in this paper, which consists of 10 new clean-energy heating systems, can effectively replace traditional coal-fired boiler heating systems. It is safe, stable, energy-saving, environmentally friendly, and efficient, reducing emissions of waste gases, SO2, NOx, and soot, thus achieving energy conservation and emission reduction goals.
