Problems solved by technology

In recent years, people have also studied a lot of biomass energy and its high-efficiency compression molding methods. In order to make the product molding effect better, some of them added potatoes or sweet potatoes as binders. The production process is complicated and the production cost is relatively high.
Some are made of mechanism charcoal from waste biomass materials and some combustion aids. Biomass waste accounts for 95% of the mechanism charcoal, and the rest are chemical materials. Although the chemical composition is changed, there are still problems such as environmental pollution in its combustion

Abstract

The invention discloses a biomass formed fuel which is prepared from, by weight, 50-60 parts of caragana microphylla, 20-30 parts of dry distillers' grains, 10-15 parts of tea seed hull, 10-15 parts of palm hull, 10-15 parts of return sludge, 3-6 parts of high clay and 2-5 parts of burning improver. Caragana microphylla is adopted as a main raw material, and reasonable proportioning of the dry distillers' grains, the tea seed hull and the palm hull and reasonable selecting of the burning improver are performed, so that the obtained fuel is high in burning value, compact in particle and supportive of long-time storage; forming rate during processing is increased effectively, and biomass fuel yield is increased.

Description

technical field [0001] The invention relates to the field of fuel technology, in particular to a biomass briquette fuel. Background technique [0002] Biomass solidified briquette fuel is a new, environmentally friendly, energy-saving, and clean renewable energy source. It is widely used in industrial boilers and civilian stoves, and can replace coal, liquefied petroleum gas, and natural gas. Most of the existing biomass fuel production technologies use wood chips, straw, agricultural and forestry waste, etc. Storage and combustion issues. Since the material to be processed and granulated is a high-fiber material, and the raw material is loose, with various sizes and materials, it is difficult to press into a dense granule during granulation. In recent years, people have also studied a lot of biomass energy and its high-efficiency compression molding methods. In order to make the product molding effect better, some of them add potatoes or sweet potatoes as binders. The pro...
