Abstract

The invention relates to a high-fuel efficiency biomass fuel, and belongs to the field of fuels. According to the invention, octenyl succinic acid modified starch and bacterial cellulose are taken aswall materials, the surface of the wall materials is densified, so that the loss of effective ingredients in the processes of preparation and storage is effectively avoided, the effects of promoting combustion and improving fuel efficiency are achieved, the heat conductivity of the structure of the wall materials is improved; heat can be rapidly led into the inner part in the use process, and micro-explosion occurs to a micro-capsule structure; the occurrence of the micro-explosion, on one side, causes thermoresonance and produces secondary energy, so that the fuel can be completely burned rapidly at high temperature, and the fuel efficiency is further improved; the volume of magnesium oxide expands and shrinks in the use process, so that inner pores and melt materials in a system are redistributed, the excessive expansion of the volume of the fuel is avoided in the combustion process, and the product porosity is also effectively maintained. The invention solves the problems of low combustion efficiency and low use ratio of the current commonly-used biomass fuel.

Description

technical field [0001] The invention belongs to the field of fuels, and in particular relates to a high-efficiency biomass fuel. Background technique [0002] With the development of the world economy, the rapid increase of population and the continuous improvement of people's living standards, the world's energy demand continues to increase, resulting in a rapid increase in oil prices, and insufficient energy supply has become a bottleneck restricting the country's economic development. Energy is one of the key factors influencing the process of sustainable development. At present, my country is facing the constraints of conventional energy resources, excessive reliance on coal resources, serious pollution and low energy utilization efficiency in the use of energy. In order to reduce the impact on the environment caused by the use of fossil energy in our country and reduce our dependence on fossil energy, it is necessary to change the way of energy production and consumpti...
