Embodiment 1

[0046] The preparation of embodiment 1 basic peak material 1

[0047] Prepare raw materials according to the following weights: bituminous coal (Mongolian coal, calorific value 5800kCal / kg) 82.5kg, high-quality anthracite (calorific value 5500kCal / kg) 165kg, low-quality anthracite (calorific value 35000kCal / kg) 253kg, sulfur-fixing quicklime 11kg, sticky Binder loess 38.5kg, the gross weight of gained basic peak material raw material is 550kg.

Embodiment 2

[0048] The preparation of embodiment 2 biomass briquettes

[0049] Take 440kg of the basic peak material 1 and 110kg of sawdust in Example 1, and pulverize it so that the maximum particle size of the powder is less than 3mm, and the powder with a particle size of less than 1mm is not less than 70%; add 75kg of water, stir and mix evenly, 24 hours After compression molding, obtain biomass briquettes

Embodiment 3

[0050] The preparation of embodiment 3 biomass briquettes

[0051] Raw materials are prepared by the following weights: 330 kg of the base peak material raw material in Example 1, 110 kg of sawdust, 55 kg of coke powder, and 55 kg of cement.

[0052] Mix and grind the raw materials except cement evenly. The particle size of all powders is less than 3mm, and the powder with a particle size less than 1mm shall not be less than 70%. Add 82.5kg of water and mix well. After 24 hours, add cement, stir evenly, and press to form. Cover with thatch for 24 hours to slow down the evaporation of water and keep healthy. Obtain biomass waterproof briquettes.

[0053] After 24 hours, take a sample and soak it in water, soak it in water for 24 hours to check the quality, clamp it with iron clips, and if it does not scatter or drop corners, it proves that the waterproof quality and strength are qualified.

Abstract

The invention discloses a bio-briquette and a method for the same. The bio-briquette comprises following components in portion by weight percent: 0 to 20 portions of bituminous coal, 20 to 35 portions of anthracite coal, 30 to 60 portions of low-grade anthracite coal, 0 to 30 portions of biomass, 0 to 4 portions of sulfur-fixing agent and 0 to 10 portions of binding agent; the bio-briquette can also comprises 7 to 15 portions of water-proofing agent. In the bio-briquette of the invention, the addition amount of the biomass can reach a very high value, if materials are reasonably mixed and used, the consumption of the binding agent such as sienna is obviously reduced or the sienna is not used; the bio-briquette is excellent in the sulfur-fixing effect, high in strength and uneasy to loose and drop slag; moreover, while firing, the bio-briquette has bright flames and can be completely fired, and after firing, the slag shape is good, so that the bio-briquette can be applied to boilers or small sized burners for domestic use.

Description

technical field [0001] The invention relates to the field of bioenergy, in particular to biomass briquettes, a preparation method and application thereof. Background technique [0002] With the development of the economy and the massive consumption of non-renewable energy sources, China and the world are feeling the energy shortage, and the competition for fossil energy such as oil and natural gas has intensified. As an effective way to alleviate the energy crisis is to find new energy sources to replace fossil energy, all countries in the world are turning their attention to energy sources such as wind energy, solar energy, geothermal energy, biomass energy, water energy, and ocean energy. [0003] Biomass energy refers to the solar energy stored by biomass as a carrier. It is a form of energy that comes directly or indirectly from the photosynthesis of plants. Among the various renewable energy sources, biomass is unique in that it is stored solar energy and a unique rene...
