Biological oil combustion device

Abstract

The invention discloses a biological oil combustion device, which comprises an oil storage tank, an atomization system, a steady combustion chamber, an auxiliary ignition system, a combustion air-distribution system used for providing combustion air for the combustion of biological oil, and a conveying system conveying the biological oil into the steady combustion chamber from the oil storage tank, wherein the conveying system comprises a first oil conveying passage and an oil return passage which are connected between the oil storage tank and the atomization system and are mutually and parallelly arranged, and a second oil conveying passage which is connected between the atomization system and the steady combustion chamber; the first oil conveying passage comprises at least one filter; the oil return passage is provided with a pressure transmitter; the auxiliary ignition system comprises a combustible gas conveying pipeline and a high-pressure igniter which extend into the steady combustion chamber; the combustion air-distribution system is communicated with the steady combustion chamber; and a spinning disk which can guide the rotating convection of the biological oil is arranged in front of the atomization system of the biological oil and the auxiliary ignition system in the steady combustion chamber. The device can realize the sustainable and steady combustion of the biological oil, can fully release the energy of the biological oil, and has convenient maintenance and long service life.

Description

technical field [0001] The invention relates to a combustion device, in particular to a bio-oil combustion device. Background technique [0002] With the continuous development of the world economy, energy and environmental issues have become increasingly prominent. The main energy sources currently used by human beings are oil, natural gas and coal. According to the statistics of the International Energy Agency, the lifespan of these three kinds of energy for human exploitation on the earth is only 40 years, 50 years and 240 years respectively. The development of new energy has become a major issue related to the sustainable development of human society. [0003] Biomass energy is converted from solar energy stored in plants through photosynthesis of plants and solar energy. It is estimated that the annual energy stored in plants is equivalent to 10 times the world's main fuel consumption, while the utilization of energy as energy is less than 1% of the total. Through b...

Problems solved by technology

Bio-oil is a mixture of various hydrocarbons, generally containing 20-30% water, so it is not easy to be ignited; moreover, bio-oil contains various organic acids such as formic acid and acetic acid, which are harmful to direct contact with biological Oil storage tanks, oil pipelines, oil pumps in pipelines, and combustion equipment all have strong corrosion effects. Therefore, compared with the storage, transportation, and combustion equipment of ordinary fuel oil, bio-oil storage and combustion equipment needs It has stronger corrosion resistance; in addition, the viscosity of bio-oil is relatively high, which is between heavy oil and light oil, and it cannot reduce the viscosity by heating, so it cannot be atomized by heating; at the same time, because bio-oil The stability is poor. If the viscosity is reduced by simple heating, the properties of bio-oil will be changed, and its combustion performance will also be affected; therefore, the burner specially designed for ordinary fuel oil (heavy oil or light oil) cannot guarantee the stability of bio-oil And full combustion, can not be used as a bio-oil burner
