Benefits of technology

The present invention provides a solid fuel molded product that is stable and retains its shape well. This is done by using a plant residue that is cultivated in large quantities and used as food or feed. Specifically, a solid fuel is created that is made mainly from plant material, and it does not produce harmful gases and helps reduce carbon dioxide levels.

Problems solved by technology

During these steps, fragmentation occurs and when fragmentation becomes marked, this product becomes unsuitable for use as an industrial solid fuel.

examples

[0047]A form retention stability test was made on solid fuels obtained in Examples by the following method.

[0048]100 kg of the solid fuel was put into a metal can (drum can) having a capacity of 200 liters, the can was rolled 100 m on a flat asphalt road for 3 minutes, and this was repeated 5 times (a total of 1,000 m). Thereafter, the solid fuel was taken out from the metal can and the ratio (%) of the solid fuel passing through a sieve having an opening of 10 mm or less was taken as form retention stability.

(Evaluation Criteria)

[0049]The ratio (weight) of the solid fuel passing through a sieve having an opening of 10 mm or less was calculated and evaluated based on the following criteria.[0050]0 to 5% or less: satisfactory[0051]6 to 10% or less: acceptable[0052]11 to 15%: unsatisfactory

examples 1 to 8

[0053]Cylindrical solid fuels having an extrusion diameter of about 50 mm (length of 65 mm) were obtained from the residues of plants shown in Table 1 below as raw material compositions (each composition contained 80 wt % of the dried residue and 20 wt % of natural rubber) by means of a double-screw extruder heated at 130° C. The apparent specific gravity (bulk specific gravity), calorific value and form retention stability test result of each of the obtained solid fuels are shown in Table 1 below.

Abstract

[Object] To provide a solid fuel suitable for thermal power generation by making use of the residue left after beneficial seeds, grains or bulbs are collected.[Solution] A solid fuel which comprises a composition containing 70 wt % or more, on dry basis, of dried Arundo donax, Leucaena leucocephala, Saccharum officinarum, Manihot esculenta, straw, seaweed, seagrass or algae and which is hot compression molded.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a solid fuel. More specifically, it relates to a solid fuel making effective use of the residue left after beneficial seeds, grains or bulbs are collected from plants which are cultivated in relatively large quantities or grow in nature.[0002]Much more specifically, it relates to a solid fuel which makes effective use of the above residue obtained from specific plants, produces as small an amount as possible of a harmful gas or residue after combustion, generates a large quantity of heat and leads to the suppression of the production of carbonic dioxide, especially a solid fuel suitable for use as a fuel for thermal power generation.DESCRIPTION OF THE PRIOR ART[0003]The causes of global warming which is one of the global environmental issues include an increasing amount of carbon dioxide existent in air. Various approaches to the suppression of the production of carbon dioxide are being made on a global basis. As one of th...
