Handling capacity: 51000Nm3
Furnace high temperature: 1400 ℃ in the reduction section and 950 ℃ in the peroxide section
Equipment: Low NOX burner
Nanhua Company has built a new waste gas incineration treatment system, aimed at collecting and incinerating 8 streams of ammonia containing production waste gas emitted by two coal chemical production units during normal production. The flue gas generated from incineration is treated by heat recovery, FGD system, and then discharged through chimneys to meet the standards. This project can not only effectively treat the ammonia containing waste gas generated in the coal chemical production process, but also recycle the heat generated by waste gas incineration, thereby achieving efficient utilization of resources and environmental protection.
Introduction to Main Technical Processes and Equipment
Ruichang Company has adopted a two-stage incineration process to address the issue of high ammonia decomposition temperature, which can easily generate nitrogen oxides and result in substandard flue gas emissions. In the reduction stage, ammonia is decomposed into nitrogen gas and water at high temperature, while lean oxygen combustion and peroxide stage are used to reduce temperature to suppress the generation of nitrogen oxides.
The core equipment of this incineration system is the low NOx burner designed and manufactured by Luoyang Ruichang Environmental Engineering Co., Ltd., as well as the two-stage ammonia incinerator. These devices ensure the minimum generation of nitrogen oxides during incineration by accurately proportioning fuel and air, thereby meeting the environmental emission requirements of users.
Main equipment features
- Integrated structure: The entire incineration system adopts a horizontal cylindrical design, with the reduction section and peroxide section as an integrated structure, greatly improving the stability and processing efficiency of the system.
- Two stage incineration: The incineration process is divided into a reduction stage and a peroxide stage, which respectively decompose ammonia and suppress nitrogen oxides, effectively controlling the emission of nitrogen oxides.
- Pry block delivery: The equipment adopts a pry block design, which is convenient for transportation and on-site installation, greatly shortening the construction period.
- Refractory material hot flue gas pre drying: The equipment uses refractory materials for hot flue gas pre drying treatment inside, which improves the durability and safety of the system.
Process characteristics
- Furnace high temperature: The temperature in the reduction section reaches up to 1400 ℃, effectively decomposing ammonia gas; The temperature of the peroxide stage is 950 ℃, which inhibits the generation of nitrogen oxides.
- High load processing: The incineration system is designed to process approximately 51000Nm ³ of flue gas, which can meet the needs of large-scale industrial production.
- Difficult to handle: The concentration of ammonia containing waste gas can reach up to 20%, which requires high requirements for the incineration system. The use of advanced incineration technology and equipment can effectively address this challenge.
