Abstract
An electricity generation method using the strew or stalk of plant (80-90%) includes such steps as cracking reacting of the biological substance at 200-500 deg.c to generate gas, removing tar from the gas, purifying, and using it as the fuel of IC engine for generating elecricity or burning it at 800-1000 deg.C to generate steam for generating electric energy by turbine and electric generator.
Description
What the present invention relates to the plant straw of a kind of 80%-90% and/or leaf biological substance utilizes method, a kind of method of especially utilizing described biological substance to generate electricity.
Carrying out along with season replacement and agriculture production, the annual plant straw and/or the leaf biological substance that all will produce a large amount of 80%-90%, in the past, in the rural area because with these straws, biological substances such as leaf are as main domestic energy, therefore all these biological substances are acted as a fuel every year and consume, but along with growth in the living standard, people begin more the employing, oil, coal gas etc. are as domestic energy, cause the annual a large amount of straw that is produced, biological substances such as leaf accumulate to get off, owing to do not develop better purposes, and become waste, thereby cause the wasting of resources.
The purpose of this invention is to provide a kind of plant straw of the annual a large amount of 80%-90% that produces and/or method that the leaf biological substance is produced electric energy utilized, make plant straw and/or the leaf biological substance of annual depleted 80%-90% become a kind of useful resource, replace the coal, the wet goods resource that day by day reduce.
Feature of the present invention is that the plant straw of 80%-90% and/or leaf biological substance are pulverized, mix with the coal dust of 10%-20% (by weight percentage), this mixture is sent into pyrolysis reaction region continuously, heat by non-oxidizable high-temperature gas (as stack gas), Heating temperature is 200-500 ℃, make mixture generation scission reaction, produce mixed pyrolysis gas; This mixed pyrolysis pneumatic transmission is gone into the combustion zone, and combustion zone temperature 800-1000 ℃, described mixed pyrolysis gas fully burns in the combustion zone, produces burning gas; Described burning gas is sent into internal combustion turbine, drive internal combustion turbine work, drive generator for electricity generation by internal combustion turbine.
Above-mentioned mixed pyrolysis gas also can be sent into oil engine after purifying, removing tar, drive internal combustion engine, by the internal-combustion engine drives generator for electricity generation.
Above-mentioned combustion zone can be the boiler furnace in the thermoelectric power station, and the burning by mixed pyrolysis gas provides heat energy to boiler, replaces coal, fry dried food ingredients.
The mixture of biological substances such as the straw after the pulverizing, leaf and coal dust, under 200-500 ℃ of non-oxidizing gas heating, decompose rapidly and emit gas, form mixed pyrolysis gas, the composition of this mixed pyrolysis gas comprises carbon monoxide, methane, propane, butane, hydrogen, carbonic acid gas, water, oxidation tar etc., under 800-1000 ℃ and the competent condition of oxygen, this mixed pyrolysis gas can fully burn.
With plant straw and/or the leaf biomass gasification of 80%-90%, produce inflammable gas, changed form of energy, available energy is cleaned more, make the power control of energy more accurate simultaneously, thereby can drive accurate equipment such as oil engine.
