Biomass cyclone dust removal burner

Abstract

The invention discloses a biomass cyclone dust removal burner. The biomass cyclone dust removal burner is characterized in that a cyclone dust removal burner is arranged at the upper part of a furnace body and at the lower end of a furnace body fire outlet, the cyclone dust removal burner divides the furnace body into a lower burning chamber and an upper burning chamber, a secondary air supply tube consistent with the spiral direction of the cyclone dust removal burner is arranged in the upper burning chamber, the cyclone dust removal burner consists of a concave barrel and S-shaped helical blades arranged outside the concave barrel, the head ends and the tail ends of the S-shaped helical blades are connected at intervals, and the helical angles of the S-shaped helical blades are 15-30 degrees. The biomass cyclone dust removal burner can keep dust particles formed after burning in the upper burning chamber and further enhances the wall-attaching dust collection effect under the centrifugal action, so that the burning effect, the dust removal performance and the fire purity of the burner are remarkably improved, the dust emission concentration is less than or equal to 5 mg / m<3>, the fume blackness reaches Ringelmann 0 grade, dust larger than 30 micrometers cannot overflow, a smoke-free and dust-free effect can be basically achieved, and the specifications of the biomass cyclone dust removal burner are higher than those of like products in the prior art.

Description

technical field [0001] The invention relates to the technical field of fuel equipment, in particular to a burner in this field, in particular to a biomass cyclone dust removal burner. Background technique [0002] In recent years, the development and utilization of biomass energy has attracted more and more attention, and is being gradually promoted and applied. Biomass fuel is a new type of environmentally friendly fuel, which has the characteristics of cleanness, high calorific value, and high combustion rate. The combustion methods of most biomass burners in the prior art are basically the same as those of traditional coal-fired furnaces, either feeding from above or from below. The disadvantages of low efficiency and large combustion smoke. [0003] For example, the utility model of Chinese Patent Publication No. CN201285034Y discloses a biomass burner, which adopts boiling gasification combustion and tangential swirl air distribution design, the combustion rate can re...

Problems solved by technology

[0005] Another example is the utility model with the authorized announcement number CN 202229173U disclosing a cyclone dedusting type burner. In order to achieve the dedusting effect, the burner has a special centrifuge chamber, the combustion is more sufficient, and the dedusting effect is also better. Technical problems of insufficient combustion and large combustion smoke

However, due to the addition of centrifugal chambers and other accessories, the entire burner has a large volume, relatively complicated structure, and high cost

[0006] Another example is the utility model with the authorized announcement number CN201391875Y disclosing a blowing air combustion furnace with a built-in independent cyclone dust collector, which is a combination of a dust collector and a burner. Combustion, Combination yields no new functionality
