Engine Tables Spreadsheet
INTRODUCTORY WORDS TO THE TOOL
Dear Gasification Colleagues.
I am pleased to offer to the gasification community a simple tool aimed at assessing technical pre-feasibility studies of biomass gasification engine powered systems.
The tool, which has been set up on Excel spread sheet format, is based on the Engine Table from Fluidyne Gasification, New Zealand. www.fluidynenz.250x.com Each engine, depending on its rpm value, is modeled on a separate sheet.
In order to assist the gasification community, in having a tool capable of helping in assessing technical pre-feasibility analysis, it has been enhanced, by adding some further outputs such as:
These added outputs stem basically from integrating the original Engine Tables with other equations and data obtained from reported experiences and literature.
Diesel replacement is reported in two units providing choice of assessing how much diesel is saved, in dual fuelled engines, depending on how the information is to be used.
As you will see the tool allows the end user to handle basically two input data:
The first input, of course, follows the same strategy previously defined by the Fluidyne Engine Table calculations, and the second added by myself. This allows a variable calorific value of producer gas to be taken into consideration, making this tool a little closer to real world gasifier functioning. When using the tool the author suggests first, to input gas calorific value and then, analyzing output of varying engine swept volume for a defined engine rpm.
Finally, I would encourage the gasification community to send comments, suggestions, or correction to help improving the tool.
Thanking you in advance.
