Problems solved by technology

[0002] With the continuous development of the global economy, human demand for energy continues to increase, while oil, natural gas, coal and other energy resources are constantly decreasing. The development of biomass renewable energy has become a focus of attention from all walks of life. my country is a solid biomass In a large energy country, biomass raw materials such as various crop by-products, forest waste and domestic waste are extremely rich, but due to the lack of research, many types of raw materials have been used due to large ash content, low heat of combustion, high sulfur content or other problems. Therefore, it is necessary to deal with fuels with different combustion properties, reduce the use of additives such as binders, and simplify the preparation process and raw material costs

Embodiment 1

[0018] A kind of effective anti-slagging fuel rod, after the tomato vines after harvesting, oil-absorbed hair felt and fennel shells are softened by steam, they are extruded into fuel rods with a moisture content of less than 15% by a flat-film granulator ;

[0019] Among them, the weight ratio of tomato vine: hair felt after oil absorption: fennel shell is 6-7:2-3:1-2.

[0020] A method for preparing an effective slagging-resistant fuel rod, specifically comprising the following steps:

[0021] (1) Squeeze the tomato vines with a press to obtain dried tomato vines and squeezed juice with a moisture content of less than 10%, and crush the dried tomato vines into particles with a particle size of less than 3mm with a pulverizer to obtain crushed tomato vines for later use. Concentrate the squeezed juice to a quarter of its original volume at 35-45°C to obtain concentrated juice for later use;

[0022] (2) Dry the oil-absorbed hair felt at 60-70°C until the water content is le...

Abstract

The invention discloses a fuel rod with high slagging resistance and a preparation method thereof. The preparation method of the fuel rod comprises the following steps: softening tomato vines without fruits, hair felts after oil absorption and fennel abortive shells and extruding the raw materials into the fuel rod with a water content being smaller than 15% by a flat membrane granulator, wherein the weight ratio of the tomato vines to the hair felts after oil absorption and the fennel abortive shells is (6-7) to (2-3) to (1-2). Compared with the prior art, the fuel rod with the high slagging resistance has the following advantages that the raw materials are convenient to take and use, the preparation method is relatively simple, the large-scale production is easy to implement, the raw material components are simple, the consumption of adhesives and desulfurizers is reduced, the secondary pollution is avoided, the fuel rod is compact in structure and high in production cost, the combustion heat reaches over 4500Kcal / kg, the combustion of the fuel rod is complete, the fuel rod can replace fossil energy, the hydrogen content reaches 6-8%, the ratio of volatile components is greater than 75%, the fuel combustion characteristic is excellent, the slagging rate is low, and the fuel rod has high slagging resistance.
