Various assessment tools are applied to comprehensively investigate a glycerol-to-hydrogen production system. These tools investigate the chemical reactions, design and simulate the entire hydrogen production process, study the energetic and exergetic performances and perform parametric analyses (using intuitive and design of experiment-based methods).Investigating the chemical reaction of steam glycerol...
A micro-CCHP (micro combined cooling, heating and power) system is proposed and investigated. It mainly consists of an internal combustion engine (ICE), an adsorption chiller (AD), a thermal management controller (TMC) and some other devices. The waste heat of ICE is collected and managed by the TMC. So the waste heat can be automatically assigned to different water cycles for heating, cooling, or...
LDAC (liquid desiccant air-conditioning system) is promising for reducing the energy consumption, and improving the indoor air quality. In this paper, the operation performance of LDAC with internally cooled/heated dehumidifier/regenerator was simulated and optimized. The cooling tower and solar collectors were employed as the cooling/heating source. Four nested iteration loops were developed and...
In this paper, we introduce a dynamic model of a thermal adsorber powered by solar energy. The system operates with silica gel (as an adsorbent) and water (as a refrigerant). The Finite Difference approximation was used; the obtained numerical model was then incorporated in a MATLAB code in order to solve the system of algebraic equations modeling heat and mass transfers. The real ambient temperature...
Lignite is a kind of low rank coal with high moisture content and low net heating value, which is mainly used for electric power generation. However, the thermal efficiency of power plants firing lignite directly is very low. Pre-drying is a proactive option, dehydrating raw lignite to raise its heating value, to improve the power plant thermal efficiency. A pre-dried lignite-fired power system integrated...
Adequate supply of cleaner, affordable, and reliable electricity is critical for the growth and prosperity of any economy. The Government of Ontario, Canada's largest province both by population and by electricity generation capacity, has enacted a long-term energy plan in 2007 to ensure reliable, sustainable and cost-effective supply of electricity. To better understand the long-term dynamics of...
