Composite biomass particle fuel

Abstract

The invention relates to the technical field of biomass fuels, in particular to a composite biomass particle fuel which is prepared from fuel substrates, graphene and coconut shell powder. The fuel substrates are prepared from wheat straws, wood chips, corncobs, peanut shells, rice straws, rice hulls, oil-tea shells and cottonseed hulls. The composite biomass particle fuel has the advantages thatthe fuel is high in combustion efficiency, moderate in combustion speed and long in combustion continuing time, combustion heat can be gently released, heat is continuously supplied and the like. Thefuel is quite suitable for meeting production requirements of finish machining enterprises.

Description

technical field [0001] The invention relates to the technical field of biofuels, in particular to a composite biomass particle fuel. Background technique [0002] Due to its high energy, environmental protection, low price, convenient use, and renewable characteristics, bioenergy has become a hot energy research field, and has attracted widespread attention from governments and scientists around the world. In the United States, Sweden and Austria, the application of bioenergy has accounted for 4%, 16% and 10% of the country's primary energy consumption respectively. my country also attaches great importance to the development and utilization of bio-energy, but the current research focuses on biogas engineering technology, straw gasification centralized gas supply technology and landfill power generation technology. For the research and development, production and utilization of biomass fuel products And so the research has only just begun. [0003] Biomass fuel usually refe...

Problems solved by technology

[0005] However, some problems have also appeared in the promotion and use of biomass fuels. Because the raw materials of biomass fuels have low ignition points and high purity, their combustion efficiency is generally high, but the accompanying problem is the burning speed. Soon, a large amount of heat can be released in a short period of time. For most users, this feature of biomass fuel will not affect normal use. However, for users engaged in the finishing industry, it is often more necessary for stable and continuous The output of heat source, the rapid release of a large amount of heat in a short time will cause a sharp rise in the production temperature, seriously affecting the normal operation of the production process, not only will reduce the quality of the product, but may also cause serious damage to the production equipment and facilities

Moreover, due to the high combustion speed, the corresponding combustion duration will be shortened. When the production process takes a long time, it will face the need to increase or replace fuel midway, thus putting forward higher requirements for actual production conditions. At the same time Increased technical difficulty and operating costs

The above-mentioned characteristics of biomass fuel limit its application scope to a large extent, making it difficult for many fine processing enterprises to use it as the main production fuel
