In order to improve the efficiency of a central heating system’s control system, this paper puts forward the application scheme of a frequency converter in central heating electrical automation control. In the central heating electrical automation control system, the frequency converter plays an important role. It can regulate and control the relevant equipment, realize the electrical automation of the heating system under the action of the frequency converter AC motor, and effectively adjust the performance and speed, so as to achieve the purpose of energy saving. The experimental results show that the temperature control strategy using a frequency converter automatic compensation method reduces the energy waste caused by manual regulation to a certain extent. When the speed of a water pump motor decreases to 4/5 of the original, the power consumption will decrease to about 52% of the original and save about 48% of the power; When the speed drops by 3/5, the power consumption is about 22% of the original, saving about 78% of the power. Conclusion. This technology can fully realize the demand of electrical automatic control of the heating system, greatly improve the stability and safety of the heating system, have good energy-saving effect, and greatly save energy consumption. The frequency converter has a remarkable effect in ensuring heating quality and improving heating efficiency in the heating industry.

“…27 Manipulation of various factors during the gasification process, such as feedstock concentration, oxidizing agent, temperature, or time, results in different qualities of the produced syngas. In their optimization study, Chen et al 51 found that air gasification favors H 2 generation with the use of moderate equivalence ratios. Using steam as an oxidizing agent, H 2 and CO yields are higher with elevated temperature.…”

“…It is however the catalytic-steam gasification (NiO/-Al 2 O 3 or K 2 CO 3 ) that not only increases the H 2 production, but also decreases char and tar yields. 51 Bai et al 47 studied the performance of polypropylene (PP) plastic in supercritical water. It was found that PP reaches low values of carbon efficiency (∼64%) at 800 °C, which was justified by a low oxygen content, making it difficult for PP to form a gaseous product.…”

Energy Potential of Plastic Waste Valorization: A Short Comparative Assessment of Pyrolysis versus Gasification

et al. 2021

Plastics are abundant and have a high energy content making their use in energy applications attractive. This article presents a review on plastic waste (PW) management by pyrolysis and gasification, which are two routes of thermochemical conversion (TCC) techniques. The conversion of PW and the application of its converted products are important steps towards reducing reliance on fossil fuel, enhancing closed-loop recycling of materials and circular economy. The review presented herein also focuses on product distribution and yields with emphasis on the energy content and potential integration to energy systems and grids. It is found that pyro-oils have properties similar to conventional fuels such as diesel and can partially substitute fossil fuels. In fact, the energy content of PW pyro-oils obtained by various researchers range from 41.10 -46.16 MJ kg -1 , which are close to the heating values of conventional fuels, thus are potential candidates for fuel applications. Typical treatment post conversion is also conducted to maintain the quality of the oil produced and the removal of sulphur content to conform with market standards. On the other hand, syngas produced during gasification possesses a lesser potential for fuel applications as its energy content may reach values as low as 20 MJ kg -1 in
