Embodiment 1

[0024] The raw materials used in the straw stick-shaped compact briquette fuel of the present invention include: 100% wheat straw.

[0025] Its manufacturing method is as follows:

[0026] (1) crushing wheat straw with a moisture content of about 15% to less than 30 mm;

[0027] (2) Send the above-mentioned pulverized wheat straw into a hydraulic straw forming machine, and extrude it under the conditions of a preheating temperature of about 220°C and a pressure of about 15Mpa to obtain a straw with a density of about 1100 kg / m3 and a moisture content of about 12%. Rod-shaped dense briquette; the briquette is a cylinder with a diameter of approximately 105 mm and a length of approximately 200 mm.

[0028] (3) After the obtained straw rod-shaped dense briquette fuel is lowered to room temperature, it is stored in a dry room.

Embodiment 2

[0030] The raw materials used in the straw stick-shaped compact briquette fuel of the present invention include: 100% peanut shells.

[0031] Its manufacturing method is as follows:

[0032] (1) Send peanut shells with a moisture content of about 12% into a hydraulic straw forming machine, and extrude them at a preheating temperature of about 240°C and a pressure of about 8Mpa to obtain a density of about 900 kg / m3 and a moisture content of about It is 10% peanut shell rod-shaped dense briquette; the rod-shaped briquette is a cylinder with a diameter of about 115 mm and a length of about 150 mm.

[0033] (2) After the obtained peanut shell rod-shaped dense molding fuel is cooled to room temperature, it is packaged.

Embodiment 3

[0035] The raw materials used in the straw stick-shaped dense briquette fuel of the present invention include: 50% corn stalks and 50% cotton stalks.

[0036] Its manufacturing method is as follows:

[0037] (1) crushing corn stalks with a moisture content of about 17% to less than 30 mm;

[0038] (2) crushing cotton stalks with a moisture content of about 11% to less than 30 mm;

[0039] (3) Mix the above-mentioned corn stalks and cotton stalks uniformly according to the ratio of 50% each to obtain a mixture;

[0040] (4) Send the mixture in step (3) into a hydraulic straw forming machine, and extrude it under the conditions of a preheating temperature of about 230°C and a pressure of about 20Mpa to obtain a density of about 1200 kg / m3 and a moisture content of about 13% rod-shaped dense briquette; the briquette is a cylinder with a diameter of approximately 50 mm and a length of approximately 300 mm.

[0041] (5) After the obtained straw rod-shaped dense briquette fuel is...

Abstract

A bar type dense formed straw fuel is provided, which takes agri-fiber as raw material, and is made by crushing, dehydrating and hot-pressure forming 100% straws with water content 10-17% or residues from crops. The bar type formed straw fuel is of high density, small volume, regular shape, is easy to transport and store, can be used as a substituting fuel of such fossil fuel as coal, and can be widely applicable in household biomass furnaces and middle / small boilers. The combustion process is easy to control, and the combustion is complete, free from pollution, and has null emission of CO2. The fuel is a recyclable green fuel, can promote the commercialized and industrialized development of agri-fiber energy, and drive the economy development in the countryside. The formed straw fuel is widely applicable for heating green houses, heating water, bathing, and in life of the people. As the fuel has a unique combustion feature, the fuel is widely applicable for various combustion equipments, and can reach general application.

Description

technical field [0001] The invention relates to a vegetable fuel and a manufacturing method thereof, in particular to a straw rod-shaped dense briquette fuel and a manufacturing method thereof. Background technique [0002] my country is a large agricultural country with abundant crop straw resources. About 700 million tons of various crop straws or crop processing residues can be produced every year, of which 400 million tons of straw can be used as energy. However, my country's straw resources are widely distributed, and the collection, storage, and transportation caused by seasonal and weather changes are very difficult, which is not convenient for industrialized utilization; at present, serious environmental pollution and resource waste are caused by improper and ineffective utilization. The extruded molding fuel can greatly increase the utilization value of straw, expand the utilization range of straw energy, and promote the industrialization and commercialization of ru...
