Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a biochar briquette fuel and its preparation method, which solves the problem that the current biochar briquette fuel has high production cost and energy consumption, and the biochar briquette fuel after molding The anti-fall performance is poor, and it is not convenient for long-term storage and transportation of fuel. Referring to the Chinese patent publication No. CN104403713A, a biomass carbon fuel and its preparation method are proposed. In this scheme, corn starch is used as a raw material to prepare an adhesive. Adhesives are added to the molding of biochar fuels to increase the compressive strength of biochar fuels, but the cost of using cornstarch to prepare adhesives is high, which reduces the economic benefits of biochar fuels. The structure of the molding equipment for material carbon fuel is relatively complex, and the cost is relatively high

Abstract

The invention discloses biomass charcoal briquette fuel and a preparation method thereof. The biomass charcoal briquette fuel comprises charcoal powder and a binder, and the mixing mass ratio of the charcoalpowder to the binder is 15: 100. According to the preparation method of the biomass charcoal briquette fuel, konjac powder is adopted as the raw material to prepare the binder, the prepared binder and the charcoal powder are uniformly stirred according to the mass ratio of 15: 100, and the mixture obtained by uniformly mixing the binder and the charcoal powder is put into an electric heating constant-temperature drying oven. The binder prepared from the konjac powder is relatively low in cost; by adopting the preparation process, the crystal form of konjac powder particles can be destroyed, so that the molecular chain of the konjac powder can be fully stretched, the micro-surface of a film formed by the gelatinized glue solution is smoother and more compact, thermal stability is also improved to a certain extent, and the biomass charcoal briquette fuel can have relatively good adhesiveness, so that the anti-falling performance of the biomass charcoal briquette fuel is further improved, thus ensuring that the biomass charcoal briquette fuel is not prone to damage in a long-distance transportation process.

Description

technical field [0001] The invention relates to the technical field of fuel preparation, in particular to a biomass charcoal shaped fuel and a preparation method thereof. Background technique [0002] Biomass fuel is green energy, which is encouraged by national policies. It has the following characteristics: 1. Typical low green energy: low-carbon combustion is mainly volatile, and its fixed carbon content is about 15%, which is a typical Low-carbon fuel, the sulfur content is lower than that of diesel, only 0.05%, and the emission of SO2 can be realized without setting up a desulfurization device; the ash content is 1.8% to 2%, which is about 1 / 10 of coal-based fuel, and the setting is simple The dust removal device can achieve the dust emission standard; the nitrogen content is low, the oxygen content is high, and less NOX is generated during combustion. 2. It can realize the ecological "zero" emission of greenhouse gas CO2, and the energy comes from the absorption of na...
