Production process of machine-made charcoal

Abstract

The invention discloses a production process of machine-made charcoal. The process comprises the following steps: preparation of raw material: collecting raw material such as bamboo saw-dust, wood saw-dust, leftover materials and peanut shell and drying until the water content of the raw materials is not more than 5 percent; pulverizing: pulverizing the dried raw material into particles with the particle size of less than 6mm by using a pulverizing machine; drying: drying the pulverized raw material again; bar-making: pressing the dried raw material into a bar with a central hole under the actions of the pressure of a screw rod and high-speed rotation centrifugal force at a high temperature; charcoal-making by utilizing a furnace kiln: carrying out combustion charring the bar at the temperature of 800-1,000 DEG C under an oxygen-deficient condition to ensure that the carbon content reaches up to 85-90 percent. The machine-made charcoal prepared through the production process is high in density, high in carbon content, high is has a heat value, clean and environmental-friendly, long in combustion time and low in cost.

Description

technical field [0001] The invention relates to a production process of a novel solid fuel, and more particularly relates to a production process of machine-made charcoal. Background technique: [0002] Humans have a long history of using charcoal. Charcoal is widely used as fuel, such as heating, barbecue, and hot pot fuel. Charcoal is made by burning or pyrolyzing wood under anaerobic conditions. However, due to the increasingly scarce forest resources , The use of wood to make charcoal will increase the cost of making charcoal; in addition, cutting down a large number of trees will destroy the natural ecological environment; charcoal prepared by general processes has a short burning time and low calorific value, which does not meet the requirements of energy conservation and environmental protection. The country has now banned logging and burning raw charcoal. Invention content: [0003] The purpose of the present invention is to provide a machine-made charcoal with hi...
