Advanced Heat Pump Systems Using Urban Waste Heat “Sewage Heat”
Mitsubishi Heavy Industries Technical Review Vol. 52 No. 4 (December 2015) 80 Advanced Heat Pump Systems Using Urban Waste Heat “Sewage Heat” YOSHIE TOGANO*1 KENJI UEDA*2 YASUSHI HASEGAWA*3 JUN MIYAMOTO*1 TORU YAMAGUCHI*4 SEIJI SHIBUTANI*5 The application of heat pumps for hot water supply and heating systems is expected. Through this, the energy consumption of hot water supply and heating, which account for a substantial proportion of the total energy consumption in a building, will be reduced. The level of reduction can be dramatically increased by use of "sewage heat," which is part of waste heat in an urban area. So far, however, it has been difficult to determine whether sufficient technical or basic data available to widely use sewage heat exists. Therefore, demonstrations on the evaluation method for the potential of sewage heat in an urban area and the actual- equipment scale of verification using untreated sewage were conducted to understand the characteristics of sewage heat, and major technologies for use of sewage heat were developed. The technologies were applied to the system using sewage heat, and the system achieved a 29% reduction in the annual energy consumption and a 69% reduction in the running cost in the hot water system in lodging facilities compared to the conventional system using a boiler. The depreciation timespan of the difference in the initial cost between the conventional system and the heat pump system is about four years, and this system has an economically large advantage. In this report, the results obtained through the development and the demonstrations are systematically organized and the technical information needed for introduction of use of sewage heat is provided. -
Energy Recovery from Waste Incineration—The Importance of Technology Data and System Boundaries on CO2 Emissions

However, it has not been previously shown explicitly which key parameters are most crucial, how much each parameter affects results and conclusions and how different aspects depend on each other. The interconnection between waste incineration and the energy system is elaborated by testing parameters potentially crucial to the result: design of the incineration plant, avoided energy generation, degree of efficiency, electricity efficiency in combined heat and power plants (CHP), avoided fuel, emission level of the avoided electricity generation and avoided waste management. CO2 emissions have been calculated for incineration of 1 kWh mixed combustible waste. The results indicate that one of the most important factors is the electricity efficiency in CHP plants in combination with the emission level of the avoided electricity generation. -

ARTICLE INFO ABSTRACT Keywords: This study reports operational information from a commercial-scale Aerated Static Pile (ASP) composting system Compost energy recovery with energy recovery, one of the few currently in operation globally. A description of this innovative system is Aerated static pile composting followed by operational data on energy capture efficiency for 17 experimental trials with variable compost vapor Compost heat recovery and heat sink temperatures. Energy capture was directly and predictably related to the differential between Alternative energy compost vapor and heat sink temperatures, with energy capture ranging from 17,700 to 32,940 kJ/h with a Waste to energy compost vapor temperature range of 51–66 °C. A 5-day temperature lag time existed between compost pile formation, and when compost vapor temperatures were sufficiently high for energy recovery (≥50 °C). -

Design and Experimental Study of HTSG for Waste to Energy: Analysis of Pressure Difference
energies Article Design and Experimental Study of HTSG for Waste to Energy: Analysis of Pressure Difference Jeachul Jang ID , Sunhee Oh, Chongpyo Cho and Seong-Ryong Park * ID Energy Efficiency and Materials Research Division, Korea Institute of Energy Research (KIER), Daejeon 34129, Korea; [email protected] (J.J.); [email protected] (S.O.); [email protected] (C.C.) * Correspondence: [email protected]; Tel.: +82-42-860-3224 Received: 18 June 2018; Accepted: 5 July 2018; Published: 11 July 2018 Abstract: The purpose of the present study is to analyze pressure difference changes inside a high-temperature steam generator (HTSG), which produces steam using the heat generated by waste incineration and decreases the pressure of the produced steam while increasing its temperature. The high-temperature, low-pressure steam produced by a HTSG is used for hydrogen production. Therefore, the steam temperature must be at least 700 ◦C, and the pressure must be lower than 300 kPa; hence, a device is needed to increase the steam temperature in the boiler and decrease the steam pressure. The physical behavior of the device was modeled and experimentally validated. The modeling and experimental results demonstrated good agreement when the steam was not preheated; however, an additional pressure drop required consideration of the opposite case. Keywords: high-temperature steam generator (HTSG); superheater; waste to energy (WtE); sudden effect; pressure difference 1. Introduction Waste to energy (WtE) has the advantages of reducing waste and transforming the energy obtained during incineration to a new form of useful energy [1]. In addition, the waste heat that is dissipated during incineration can be used to generate steam in a waste heat boiler, which can then be used directly or supplied to a turbine for power generation [2,3]. -
