This report summarizes the development of a calculation program estimating the profitability of converting a peak-load oil-fired boiler to pellets. To convert an oil-fired boiler to pellets a new fuel handling system must be designed. Changes also have to be made to some other components. Since there are many different techniques for transportation, storage and treatment of the fuel only the most interesting techniques from Swecos experience and interest were included in the study. The capacity of the different parts in the system was dimensioned based on the power of the boiler after conversion. To estimate prices, installed power and dimensions manufacturers and distributers were contacted. The acquired data were then used to produce curves for how the price, effect and dimension varied for different components depending on the size of the plant. For some components non-sufficient data were acquired to establish curves and other estimates had to be done. The program is restricted from the public, so the code and the program are not shown in their entirety. In the report schematic pictures of the input and output page are shown as well as some sensitivity analyses with normalized values. The program can probably give an indication on rough prices, installed effects and dimensions. Since sensitivity analyses are undertaken and economic scenarios are investigated the user also gets a sense of what influences the economic outcome the most. Unfortunately no validation data could be found during the project, so validation will have to be made during future projects.
