Abstract: A connection between gas producer chamber design parameters and installation exploitation operational modes as well as fuel parameters, was studied. A multi-factor experiment that connects this parameters, was planned and installation tuning characteristics were built based on results. Using these results, under different fuel parameters, allows to gain maximum productivity under given conditions. Some recommended fuel parameters for effective gasification are substantiated also based on experimental data.

1. INTRODUCTION
The gas producing process and its stability depend greatly on technical and operational parameters of gas producer installation and physical and chemical characteristics of straw (Basu, 2013; Higman and van der Burgt, 2008; Knoef, 2012; Kollerov, 1950; Muller et al., 2016). That is why raw material preliminary preparation for gasifying (Golub et al., 2015; Kolerov, 1950; Mezin, 1948) and coordination between gas producer design parameters and gas blowing mode are topical questions (Kolerov, 1950;Mezin, 1941;Los et al., 2014;Tsyvenkova and Golubenko, 2014). That will also allow us to gasify different types of biomass like corn stalks and cobs, sunflower chaff, Miscantus, wood etc. without big changes in design of the gas producer optimized for straw, gaining maximized heat productivity from equipment, depending on raw material.
The analysis of written sources dedicated to improvement of the physical and mechanical properties of straw by processing it into pellets, briquettes, and fuel granules shows that this problem is enough explored. But these technological processes are energy cost and expensive (EU energy in figures, 2012; Geletuha and Zheleznaya, 2014; Melnichuk et al., 2011). A new method of straw preliminary preparation for gasifying was proposed - making a poly-fractional mixture from it, which makes its further usage in thermotechnical equipment economically advantageous.
There is a great variety of gas producer designs depending on way of receiving and appointment of producer gas, also by gas producer installation type, by degree of automatization and mechanization, by type of raw material (Mezin, 1948). In books (Basu, 2013; Knoef, 2012; Kolerov, 1950; Mezin, 1948; Pandey, 2015) the main accent was on creating an ideal gas producer design for exact type of raw material and main method of reducing moisture content to the acceptable level when operation of the gas producer will...
