Abstract

The invention discloses a special biomass combustion system and process for a ceramic roller kiln, and relates to the technical field of energy saving and emission reduction of the ceramic roller kiln. The invention adopts the high temperature and low oxygen flue gas and hot air discharged from the ceramic roller kiln as the The gasification agent of the biomass gasifier can improve the gasification efficiency of the biomass gasifier and reduce the emission concentration of nitrogen oxides in the kiln; the waste heat of the high-temperature flue gas discharged from the ceramic roller kiln is used to heat the liquid pentoxide. After gasification of liquid pentane into gaseous pentane, it is evenly mixed with biomass gas in the gas main pipe, which effectively improves the calorific value of fuel gas and can basically reach the calorific value of natural gas. Using the premixed combustion method, biomass fuel gas is preheated by high temperature flue gas and reaches 350°C, firstly mixed with gaseous pentane in the fuel main pipe, and then fully mixed with hot air in the premixer in proportion before entering the combustion chamber. mouth.

Description

technical field [0001] The invention relates to the technical field of energy saving and emission reduction of ceramic roller kilns, in particular to a biomass combustion system and a process for ceramic roller kilns. Background technique [0002] At present, most ceramic roller kilns use natural gas as fuel. Natural gas has high calorific value and good environmental protection, and has been widely used. However, natural gas is expensive, which can easily lead to high operating costs of ceramic roller kilns. In addition, the use of natural gas fuel, due to its high calorific value, is prone to problems such as excessive combustion temperature and excessive nitrogen oxide emissions, which need to be solved urgently. In addition, the waste heat of the ceramic roller kiln is not fully utilized, resulting in a high energy consumption of the ceramic roller kiln. A better way to solve this problem is to use biomass gas, that is, to use biomass gasifier to gasify biomass waste ...
