Biomass Power Plant

Biomass direct combustion power generation is the most simple but effective way in dealing with environmental issues and energy crisis. A comprehensive diagnosis with accurate evaluation of energy saving potential of a given biomass power plant is of great importance in lowing the cost of generating electricity, reducing the consumption of energy and pollutant emissions [1]. This paper throws light upon an innovative energy consumption diagnosis method-the specific consumption analysis theory, which is based on the First and Second law of thermodynamics [2,3]. Taking a given biomass power plant of National Energy Group as an example, mathematical models are made based on all the components and processes. The specific consumption analysis theory is employed to calculate the specific consumption within the biomass power plant using design parameters under design operating conditions, thus demonstrating the specific consumption distribution in the power plant, which provides theoretical basis for energy-saving and optimization in biomass power plant.

Thermal power industry promotes economic development in a high speed, and it also brings the problem of resources and the environment. Building the evaluation index system of the thermal power plants’ ability of energy saving and emission reduction, we made use of the analytic hierarchy process to determine the weight. And the fuzzy comprehensive evaluation was applied to a thermal power plant in Shandong Province. We obtain following conclusion: the primer factor which confines its ability of energy conservation and emission reduction is pollutant emission. On this basis, we put forward the specific implementation measures from fiscal policy, tax policy and monetary policy, aim is to accelerate the development of China’s energy saving and emission reduction.

The Impact

The premise that analyzing and studying the factors that effect university town ecological physical environment (UTEPE), UTEPE impact factors are the thermal environment, sound environment, light environment, eco-energy saving design. This paper establishes the evaluation method for UTEPE which is based on fuzzy math. We evaluate the quality of UTEPE comprehensively in this way. Renewable energy, nontraditional water source, green construction materials, water-saving appliances, energy-saving lamps, bicycle & public traffic system are very important for creating good quality physical environment in university town. In this paper, according to the impact factors of the UTEPE and using the fuzzy mathematical theory on evaluating the UTEPE comprehensively can reflect the real situation more objectively and accurately. The construction of model is simple and practical. Comprehensive evaluation utilizes the combination of the general public survey and expert evaluation, which benefits to reflect the democratic spirit. It also provides the reference to improve the UTEPE.
