Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings. As shown in the accompanying drawings:

[0035] A direct combustion decentralized heat supply method for a biomass pyrolysis furnace. The heat supply combustion device of the pyrolysis furnace is composed of a plurality of burner groups, and all the burner groups are arranged on the upper part of the pyrolysis furnace. The upper part is distributed along the axial direction, and each burner group is composed of multiple small burner nozzles. The maximum temperature of the combustion area in the pyrolysis furnace is controlled below 1600°C.

[0036] In the direct combustion decentralized heat supply method of the biomass pyrolysis furnace, the fuel and oxidant for the combustion and heat supply of the pyrolysis furnace are separated before entering the pyrolysis furnace, and in the pyrolysis furnace are non-premixed combustion.

[0037] The direct combustion decentral...

Abstract

The invention discloses a direct combustion dispersed heat supplying method for a biomass pyrolysis furnace, which relates to the technical field of biomass thermochemistry. A heat supplying combustion device of the pyrolysis furnace comprises pluralities of combustor groups, all the combustor groups are dispersedly distributed on the upper portion of the pyrolysis furnace along an axial direction, each combustor group is composed of pluralities of small combustor nozzles, and the highest temperature of a combustion area inside the furnace is below 1600 DEG C; fuels for supplying heat to the pyrolysis furnace and oxidizers are separated before entering the pyrolysis furnace and conduct non-premixed combustion inside the furnace; the pyrolysis furnace with a fixed outer casing is horizontally arranged and stirs biomass inside the furnace through the rotation of a stirring shaft with a stirring rod; during operation, the highest temperature inside the combustion area can be adjusted by adjusting the amount of externally supplied fuels and/or inert component content in the oxidizers and/or by adjusting the rotation speed of the stirring shaft with the stirring rod. The direct combustion dispersed heat supplying method is applied to biomass pyrolysis treatment, and meets engineering application requirements of intermediate-temperature rapid pyrolysis of biomass raw materials and of subsequent entrained flow gasification through the technology of 'direct combustion dispersed heat supplying'.

Description

technical field [0001] The direct combustion decentralized heat supply method of the biomass pyrolysis furnace of the present invention relates to the technical field of energy and chemical industry; in particular to the technical field of thermochemistry of biomass; in particular to the medium-temperature rapid heating of biomass in order to realize the entrained gasification of biomass The technical field of pyrolysis treatment; specifically relates to the technical field of direct combustion decentralized heat supply method of biomass pyrolysis furnace. Background technique [0002] Biomass is an organic substance produced by absorbing carbon dioxide in the air through photosynthesis. It is widely distributed, has a large amount of availability, and is the only renewable natural raw material that contains hydrocarbon components and heat energy and can be stored; using biomass for energy Utilization and chemical production, with CO 2 Characterized by zero emissions.
