Problems solved by technology

[0002] Because straw is cheap and has a wide range of sources, it is still the fuel for cooking and heating commonly used by farmers in cities and towns. However, because the moisture of straw is not easy to control, especially in rainy days and dog days, straw is prone to mildew and dampness. Not conducive to burning
Although No. ZL01107033 Chinese patent has disclosed the patent that the title of invention is " biomass compound briquette production technology " on August 22, 2001, this patent has solved the problem that the moisture of stalk is too high and difficult to control, but, because in this In the patent, straw accounts for about 40% and lignite accounts for about 60%. Therefore, the production of this biomass composite briquette still consumes a lot of coal, which is not conducive to energy saving
In addition, although a certain amount of sulfur-fixing agent is added to the biomass composite briquette, the flue gas after the combustion of the biomass composite briquette still contains sulfide, which is not conducive to environmental protection.

Abstract

The invention relates to biological complex shaped fuel and the preparation method. The comprised components of fuel and their proportion are as follows: straw 80- 95 uints, refined coal 5- 20 units and sulfur- fixing agent 0.5- 1uints. The production method comprises following steps: (1) disintegrating straw with water content being 13- 17% into particles with size being smaller than 5mm; (2) disintegrating refined coal with water content being 13- 17% to particles with size smaller than 1mm; (3) mixing said straw, refined coal and sulfur- fixing agent according to said proportion; (4) feeding said mixture into shaping machine, extruding at 110- 150 Deg. C and 105- 120 Mpa, getting granular or block- shaped fuel with density being 1.2- 1.4 g / cm3 and water content being 10- 12%; (5) cooling temperature of got shaped fuel to room temperature, and packing. The fuel is characterized by convenient transportation, easy storage and no sulfur product generation, and it is a sustainable new energy.
