Abstract

The invention discloses a biomass charcoal pellet fuel used for low burning-point environment-friendly type heating and a preparation method thereof. The method comprises the following steps: 1) crushing corn straw, briquetting the corn straw, fragmenting the corn straw, and performing pyrolysis, wherein pyrolysis is carried out under anoxic environment, and charing the material at the temperatureof 220-270 DEG C to obtain biomass charcoal; 2) taking the following raw materials in parts by weight: 96-98 parts of the biomass charcoal in the step 1), 0.1-1 part of an oxidant, 0.1-1 part of a nitrogen-fixation agent, and 0.2-0.4 parts of a catalyst; and 3) performing steps of crushing, mixing and granulation on the raw materials in the step 2). The biomass is subjected to low temperature charing, a water content of the fuel is lower than 10%, the added oxidant is helpful for shortening the ignition time of the fuel, and accelerates the ignition speed of the fuel; and the addition of thenitrogen-fixation agent can effectively reduce the discharge of a nitrogen-containing compound in a gas phase, wherein the discharge capacity of NOX is reduced by 35.3-38.7%.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly new energy materials, and in particular relates to a low ignition point environment-friendly biomass charcoal particle fuel for heating and a preparation method thereof. Background technique [0002] With the development of science and technology, issues such as environmental pollution and energy crisis have received widespread attention, and the resource utilization and emission reduction of agricultural and forestry wastes have become the focus of social development today. Effectively alleviating the problem of civil heating is an effective way to reduce domestic pollution, and it is also a powerful driving force for the coordination and sustainable development of natural environment and social resources. [0003] Civilian heating problems often come down to the selection of heating methods and domestic fuel types. my country's civil heating methods are mainly direct-fired heating ...
