<p>This paper introduces the structure and working principle of biomass fuel hot stove, and analyses the existing problems in the combustion process. Simultaneously, the paper proposes the optimization about the wall high temperature of the hot stove, which is the main issue in the hot stove.</p> <p>Biomass resources in China is very abundant.only the amount of resources of agricultural wastes (such as straw) each year is equivalent to 3.08 tons of standard coal. The biomass briquette is compressed with loose, amorphous materials, such as straw, rice husk, sawdust, wood chips, into a shaped, denser solid fuel with the method of mechanical pressure. It has the advantages of small size, high density, easy storage and transportation, combustion stability, long cycle, high combustion efficiency, low contaminant levels in ash and flue gas.

Surface finish and Manufacturing process has a prominent role in the fatigue life of a machine component. Fatigue strength of a material generally increases with the surface finish. But the super finishing process like electro polishing reduces the fatigue strength of the material. In Abrasive flow machining it is found that surface finish and fatigue strength always increasing. In Abrasive flow machining the fatigue strength is mainly governed by the process variables extrusion pressure, abrasive concentration and mesh size. This research studies the influence of the process variables on the fatigue strength of the material. In this study an approximate surface finish of 4μm is obtained after AFM. The effect of three process variables on the response function selected, fatigue strength, were studied. A statistical 23full factorial experimental technique is used to find out the main effect, interaction effect and contribution of each variable on fatigue strength. The instron machine is used to find out the number of cycles to failure of the material. The fatigue strength is obtained with S-N curve analysis.

ABSTRACT - Technology development change system management which was originally to be done manually be computerized. Benefits of systems that are considered to be managed in a computerized can benefit the company is no exception PT. Setiajaya Mobilindo. In managing the system supplies parts PT .Setiajaya Mobilindo have used technology information using desktop based program. But there are still the problem in system that runs of them were not the availability of programs to perform stock opname, Making it difficult to seeing how goods in the warehouse with data on database, the absence of a program to see a groove out of making it difficult to find the transaction goods Based on the discussion mentioned above then the researcher want to provide solutions by improving program was with the waterfall, start from analysis software needs , design , encoding , until testing. Improvement of the program will start from planning system to the stages of the design of detailed system , includes the design of a database , the design of control , the design of output input, until the technology. is expected that improvement program that has been there would be produced program to suit the needs of users and can to be the solution for the existing problems now.
