Biomass curing-forming fuel and preparation method thereof

Abstract

The invention discloses a biomass curing-forming fuel. The biomass curing-forming fuel consists of straws, saw dust, coal dust, a combustion improver, a sulfur-fixing agent and a dust-falling agent according to parts by weight, wherein the straw is one or combination of the straw of crops such as rice, wheat, soybean, corn, sorghum, cotton, rape and tobacco, a branch and a bark of trees and shrubs, rice hull, chaff and peanut coat; the combustion improver is one or more of table salt, sodium nitrate, potassium permanganate, potassium oxide, sodium nitrite and sodium hypochlorite and capable of realizing decomposition and combustion supporting at different temperatures; the sulfur-fixing agent is in a manner that sodium carbonate, calcium hydroxide and alkyl alcohol amine compounds are synergistically used and is capable of reducing discharging of sulfur dioxide; and the dust-falling agent is selected from iron sesquioxide and capable of lowering a melting point of ash and reducing dust volume. The biomass curing-forming fuel has the advantages that the combustion efficiency is high, the slag bonding and the soot formation are not generated, the black smoke is little, the fire power strong, the combustion is sufficient, the ash does not fly, the biomass curing-forming fuel is clean and sanitary and the like. The invention further discloses a preparation method of the biomass curing-forming fuel.

Description

technical field [0001] The invention relates to the technical field of biomass fuels, in particular to a biomass solidified briquette fuel, and also relates to a preparation method of the biomass solidified briquette fuel. Background technique [0002] With the continuous development of the global economy, human demand for energy continues to increase. Today, the three main energy sources used by humans are oil, natural gas and coal. They are all non-renewable energy sources, and their resources are decreasing year by year. These three types of energy will be exhausted within 40 years, 60 years and 200 years respectively. Therefore, the development and utilization of biomass renewable energy to replace non-renewable energy has become a hot spot in the world's energy field. In recent years, bioenergy technology has developed rapidly, but at the same time, some shortcomings of bioenergy have gradually emerged. The first generation of bioenergy mainly uses plant fruits, such ...

Problems solved by technology

At present, the molding process adopted by biomass solidification molding technology mainly relies on hot pressing after heating. Invention patent application published on April 7th with application number 200910182693.X, the technical solution disclosed in the above-mentioned invention patent application is to dry and pulverize all kinds of scattered and irregular crop straws and forestry wastes, etc. Under the action of certain temperature and pressure, it is pressed into rod-shaped, block-shaped or granular briquettes with regular shape and high density; this method has problems such as high energy consumption and high cost, and heating will also cause wear and tear of mechanical equipment and fuel In addition, these molding processes are all small workshops, which consume a lot of electricity per unit of goods, and the production efficiency is low, so it is impossible to achieve continuous and stable industrial production.

There is also a cold press molding method, such as the invention patent application disclosed by the State Intellectual Property Office on July 16, 2008, with the application number 200710007616.1. In order to increase the viscosity of the molding fuel, it is usually necessary to add starch glue, Clay, asphalt and other binders to solve the problems of difficult extrusion and loose structure

This undoubtedly increases the production cost of fuel, and clay, asphalt, etc. as binders will also cause serious slagging of the molded product, which will have a certain negative impact on combustion and pollute the environment.
