Clean burning bio-coal

Abstract

A clean burning bio-coal consists of 70˜90 wt % of bio-fiber material and 1˜20 wt % of coal material. With the above composition percentages for the bio-fiber material and the coal material, emission of greenhouse gases and pollution gases during burning of the bio-coal can be reduced, total heat energy producible from the bio-coal is high enough to satisfy requirements in industrial activities, and a high burn-out rate of the bio-coal can be advantageously achieved.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a bio-coal, and more particularly to a clean burning bio-coal that consists of bio-fiber material and coal material to achieve the purpose of environmental protection through recycling agricultural wastes and reducing the emission of greenhouse gases and pollution gases, and to produce total heat energy high enough to meet requirements in industrial activities.BACKGROUND OF THE INVENTION[0002]In environmental protection, recycling forms a basic spirit thereof. There is an environment-friendly charcoal, which uses agricultural wastes, such as straws, corn stalks, wood dust, and coconut shells as its major raw materials. By using the environment-friendly charcoal to replace the conventional coal material, it is able to avoid the emission of greenhouse gases and pollution gases, which are usually produced during burning of the conventional coal material, and to comply with the target of recycling in environmental protection. ...

Benefits of technology

[0006]A primary object of the present invention is to provide a clean burning bio-coal consisting of bio-fiber material and coal material at specific composition percentages, such that the alkaline bio-fiber material can neutralize the acidic coal material to thereby reduce the emission of greenhouse gases, such as carbon dioxide and sulfur dioxide, as well as other pollution gases, such as nitrogen oxide compounds.

[0007]Another object of the present invention is to provide a clean burning bio-coal that uses bio-fiber material as a main raw material thereof to achieve the purpose of recycling agricultural wastes, environmental protection, and energy saving, and uses coal material as a secondary raw material thereof to compensate the insufficient heat energy production ability of the bio-fiber material, so that the bio-coal can produce total heat energy high enough to meet requirements in industrial activities.

[0008]A further object of the present invention is to provide a bio-coal consisting of bio-fiber material and coal material that are fully blended with each other and uniformly distributed in the bio-coal, so that when the bio-coal burns, the bio-fiber material is burned out first to produce a burning porous briquette, which allows sufficient supply of oxygen into the bio-coal to enable complete combustion and accordingly increased burn-out rate.

Problems solved by technology

While the environment-friendly charcoal so manufactured has high fuel value and meets the recycling requirements in environmental protection, the plastic wastes contained therein will produce waste gas with unpleasant odor when the environment-friendly charcoal is burning.

Even if human-harmless plastic wastes are selected for use in the environment-friendly charcoal, it is still difficult for general consumers to accept it due to the bad odor.

However, the botanical fiber material provides only limited heat energy, and the currently available environment-friendly charcoal made from the botanical biomass in the agricultural wastes can not produce heat energy high enough to meet the amount needed by various industrial activities.

While the adding of coal material to the botanical fiber material can increase the producible heat energy of the environment-friendly charcoal, the added coal material inevitably results in the emission of greenhouse gases and pollution gases.
