Output 1
Conventional and Improved Furnace - a comparison

Salient Features of the Improved Furnace

* Higher efficiency and low pollution * Clean and safe working conditions
* 50% saving in Rice Husk * Furnace operated with husk only
* Saved rice husk can be made into briquettes * Briquettes can replace fuel wood
* Cheaper and more efficient * 50% reduction in processing time
* Local mistries can be trained * Lower feed rate reduces pressure

Output 2

Different screw materials are being used to reduce screw wear. These are (i) die steel with satellite ciating; and (ii) material EN9 hardened and tempered with Titanium carbide.

Test Results of Rice Husk Ash (RHA) in Combination with Ordinary Portland Cement (OPC)

Compressive strength of RHA-OPC Blocks after 7  days and 14 days of curing at differemt proportions   Percent gain in compressive strength of RHA-OPC blocks compared to OPC after 7 and 14 days of curing at different proportions

The tests in this study indicate that a proportion of 10% RHA to 90% OPC, cured for 14 days gives sufficient compressive strength for it to be used in low strength construction.
