IMPROVING THE ENERGY EFFICIENCY OF A BOILER SYSTEM FOR USING LAUNDRY STEAM OF 5 STAR BANGKOK HOTEL

Abstract

This paper is to identify the using of energy in efficiency way and to reduce using LPG to produce thermal energy and electricity, also using the thermal energy to produce hot water together with planning and developing system in future. Because of the high energy of steam system has consumed about 6 million baht per year and lost highest approximately at 18.17%. This research is conducted by surveying and measuring of the loss in steam production system, steam distribution system, and the equipment of using steam in the production process. In order to improve the system to become more efficiency and also define the measures in practical continuously. The record of the information has been used to compare with standard score in theory to improve high efficiency and develop on steam system. This study also use the engineering management conceptual to rectify the working schedule relevant with the working of boiler for reducing cost to 7%without investment. In addition, using the results is compared with investment by considering on investment and pay-back period, which can be additionally reduced by 6.14% of production process. Therefore, the results in a total cost reduction of at least 13 percents for applying in manufacturing process followed on theoretical, the calculation.
