Compound high-temperature environment-friendly biomass fuel and preparation method thereof

Abstract

The invention discloses a compound high-temperature environment-friendly biomass fuel and a preparation method thereof. The compound high-temperature environment-friendly biomass fuel is composed of the following components in parts by weight: 25-35 parts of forestry and agricultural residues, 15-25 parts of household refuse, 15-25 parts of sludge, 15-25 parts of excrement, 15-25 parts of coal powder, 15-25 parts of scrap tire colloidal particle, and 2-10 parts of combustion improver; and the combustion improver is composed of dolomite dust, urea, red mud, calcium peroxide, manganese oxide, strontium peroxide, magnesium peroxide, cerium oxide, and boric sludge. The compound high-temperature environment-friendly biomass fuel is suitable for storing for a long time without foreign smell. The burning temperature of the compound high-temperature environment-friendly biomass fuel is high and is up to 1320-1380 DEG C, and the burning efficiency is improved by about 35% compared with that of the common biomass fuel; the calorific value is 4800-5200 kilocalorie / kg and per ton of the compound high-temperature environment-friendly biomass fuel is 0.7 ton of the standard coal; and the combustion gas is in accordance with the national related provisions, the sulphur removal rate is 98% and the nitrate removal rate is 95%.

Description

technical field

[0001] The invention relates to a new energy source, in particular to a composite high-temperature environment-friendly biomass fuel and a preparation method thereof. Background technique

[0002] Agricultural and forestry waste is a large amount of waste generated during the harvesting and processing of agricultural and forestry crops, for example, the straw left in the farmland when the crops are harvested, the rice husks and chaffs left in the agricultural production process, and the branches and leaves left in the forestry production process , wood chips and leftovers from wood processing, etc., as well as residues from the food processing industry. my country is rich in agricultural and forestry waste resources. At present, agricultural and forestry wastes are loosely scattered in a large area. Except for a small part of crop straws used for livestock feed, cooking and heating, most of them are discarded in the fields as waste. There are many utiliz...
