The generator is the most popular mobile power device and backup power device in the world. It is very important for human life. Therefore, it is important to develop more efficient combustion technology in order to save energy and reduce air pollution. In this paper, a novel technology of hydrogen and oxygen compound gasoline fuel is developed. Hydrogen and oxygen gases are produced from an electrolytic cell and then mixed with the intake gasoline and air. The compound fuel is sucked into the engine combustion chamber. The hydrogen and oxygen gases can be produced immediately without any storage device of hydrogen. The experimental results show that this technology can increase the power generation and decrease emission pollution due to promoting combustion efficiency. In addition, the spark plug seat temperature increases due to higher heat value of hydrogen. This technique can reduce carbon monoxide and HC, but increase carbon dioxide. The research and development of this technique can achieve the goals of energy saving, emission reduction, relative safety, easy refitting and low refitting expense. Moreover, this research possesses academic innovation and industrial application.

The motorcycle plays an important role in the life for the people of Taiwan. However, the motorcycles’ emissions are the main moving air pollution sources. Therefore, it’s important to develop more efficient combustion technology in order to save energy and reduce air pollution. In this paper, a novel technology of hydrogen-gasoline compound fuel is developed. Hydrogen gas is released from solid state hydrogen storage tank and then mixed with the incoming gasoline. The intake valve in manifold sucks the hydrogen-gasoline compound fuel into the cylinder for combustion. A series of performance test is conducted by motorcycle chassis dynamometers. The results reveal that this technology can increase the power and torque, and decrease fuel consumption per kilo-power due to promote combustion efficiency. In addition, the hydrogen has greater heat value, so the oil temperature and spark plug temperature increase. This technique can reduce CO and HC, but increase CO2 and NOx. The engine performance is improved at rarefied hydrogen-gasoline compound fuel. Therefore, the engine performance with M.J. #98 is better than that with M.J. #110. This technique can achieve energy saving and environment-friendly purpose.

Most currently used shutters are manually operated. The design of an intelligent shutter has been proposed. The intelligent shutter can be powered by a solar battery. Photosensitive resistors have been used to determine if it is in daytime or nighttime, if it is sunny or not, and if the light is turned on or turned off. Digital temperature sensors have been used to detect the indoor temperature and the outside temperature. They are also used to determine the current season. The intelligent shutter is automatically controlled according to the above information. It is turned off at night and is set in sleep mode to save energy. It is turned on partially on sunny day in summer. In rainy day, the shutter is turned off while the indoor light is on. The intelligent shutter can also be controlled using a wireless remote controller, which makes it very friendly. It is comfort and energy-saving using the intelligent shutter. Experiments have demonstrated the applicability of the design.

Previous work has shown that wallboard can be successfully manufactured to contain up to 30 percent phase-change material (PCM), or wax, thus enabling this common building material to serve as a thermal energy storage device. The PCM wallboard was analyzed for passive solar applications and found to save energy with a reasonable payback time period of five years. Further evaluations of the wallboard are reported in this paper. This analysis looks at potential applications of PCM wallboard as a load management device and as a comfort enhancer. Results show that the wallboard is ineffective in modifying the comfort level but can provide significant load management relief. In some applications the load management strategy also serves to save a small amount of energy, in others there is a small energy penalty.

Air Removal

Energy consumption all over the world is constantly growing. To save energy, new technologies are being developed for the efficient use of energy resources. The goal of all new developments is to use less energy to provide the same level of energy supply for technological processes or buildings. The problem of energy saving is relevant for the ventilation system. Together with the removed air, a large amount of heat is lost, which is not advisable. In order to avoid these losses, heat recuperators began to be used, heating the cold supply air due to the warm air removed from the room. This development belongs to the field of energy saving. The goal is to increase efficiency by reheating the air after the heater with the help of a recuperator for a given temperature difference in the supply air before and after the recuperative heat exchanger. The development is a design of a ventilation unit with air removal and supply air ducts, combined into one housing with a separate, according to the “screw” principle, heat transfer wall, for use in the ventilation system in order to ensure an optimal microclimate in the room. Thus, as a result of using the presented device, the efficiency of the room ventilation unit is increased by reducing the energy consumption for heating the supply air with a heater.

One of the aspects for optimizing the powdered biofuel combustion technology is to ensure proper relationship between powder production and its delivery into the reactor. This paper focuses on the effect of a time delay between production and use of powdered fuel on its combustion efficiency using pine sawdust as an example. It was established that the ignition delay time increases with an increasing delay between powdered fuel production and use (i.e., the effect of sample aging takes place). A correlation between the ignition delay time, the amount of lignin radicals, and the sample's ability to release volatile combustible matter is demonstrated.

Combustion Technology

In China, there are a large number of pulverized coal-fired industrial boilers, whose steam capacities are usually relatively small. These boilers can burn only high-grade coal and have low combustion efficiency. Furthermore, the combustion emissions, such as SO2 and NOx, pollute the environment severely. Therefore it is very important and urgent to adopt economically efficient and environmentally friendly technologies to retrofit these boilers. At the same time, there are many industrial wastes, such as bagasse, wood waste, rubbish, petroleum coke and so on, need burning disposal in China. Fluidized bed combustion technology is a kind of clear combustion technology, which has many advantages, such as excellence fuel flexibility, high combustion efficiency, low pollutant emission and good turndown capability etc. So, adopting fluidized bed combustion technology, retrofitting pulverized coal-fired boiler into fluidized bed boiler can realize pure burning various wastes or co-firing with coal, which should have great economic benefits and social benefits. And the application prospect of the method is also extensive. The State Key Laboratory of Coal Combustion has successfully retrofitted a 25t/h pulverized coal-fired boiler into circulating fluidized bed boiler with in-bed tubes and downward exhaust cyclone. The retrofitted boiler can burn mixture of coal and bagasse and the steam capacity reaches 35t/h. This paper presents the retrofitting measures and the operation status of the boiler after retrofitting.

Commercial Spaces

Commercial space features essential characteristics of attracting clients and creating profits; thus, the exterior and interior designs of conventional commercial space were often made to look grandiose and overdecorated. Over time, according to commercial attributes, operator preferences, and style of the designer, commercial spaces have constantly undergone renovation into varied styles. However, the physical renovation processhas caused multiple and composite types of environmental pollution, such as waste and noise pollution caused by breaking of walls or partitions, anddecorative paint pollution, as well as the use of high-energy-consuming lighting equipment, air-conditioning systems, and decorative materials. Global pollution has caused climate change, endangering living organismsand human life. Furthermore, no effective method exists to control the problem of high greenhouse gas emissions. Therefore, this study used energy-saving design concerns of a garden-type commercial space to propose an energy-saving evaluation model. The study combined three methodologies, the Delphi method, analytic hierarchy process, and fuzzy logic theory, to construct a multi-criteria decision support system for designing green commercial spaces, and used the green spatial design of a garden café as an example to illustrate the high objectivity and adaptability of the proposed model in practical application. The study also used an international award-winning case to validate that the proposed model had practical value as a reference to support key design decisions.
