Abstract
本实用新型涉及煤粉煤气两用锅炉，其特征是该锅炉的燃烧器设有上下布置的两个狭缝式风包气矩形高炉煤气喷口，该喷口在矩形高炉煤气喷口的四周是风喷口，风入口与高炉煤气喷口的截面比是(3－4)∶5；煤粉喷口布置在燃烧器中心，在上层二次风喷口及下层二次风喷口内布置有套管式焦炉煤气喷嘴。优点是该锅炉可以全烧煤粉运行，又可以全烧煤气运行，可有效利用冶金企业在生产过程中产生的废气资源如高炉煤气、焦炉煤气，节约能源，降低生产成本，改善环境。
The utility model relates to a pulverized coal gas dual-purpose boiler, which is characterized in that the burner of the boiler is provided with two slit-type air-enclosed rectangular blast furnace gas nozzles arranged up and down, and the nozzles are air nozzles around the rectangular blast furnace gas nozzle. The cross-sectional ratio of the air inlet to the blast furnace gas nozzle is (3-4):5; the pulverized coal nozzle is arranged in the center of the burner, and the casing type coke oven gas nozzle is arranged in the upper secondary air nozzle and the lower secondary air nozzle. The advantage is that the boiler can be run entirely on pulverized coal and coal gas, and can effectively utilize waste gas resources such as blast furnace gas and coke oven gas generated in the production process of metallurgical enterprises, saving energy, reducing production costs, and improving the environment.
Description
技术领域technical field
本实用新型涉及一种电站锅炉，特别是一种煤粉煤气两用锅炉。The utility model relates to a power station boiler, in particular to a pulverized coal gas dual-purpose boiler.
背景技术Background technique
近年来随着钢企业产能的增加，高炉煤气的发生量也随着大量增加，有效地利用这部分煤气资源，减少煤气放散，降低生产成本，是应该解决的问题。现有的电站锅炉一般都是煤粉锅炉或煤粉掺加少量煤气的电站锅炉。In recent years, with the increase of production capacity of steel enterprises, the amount of blast furnace gas has also increased significantly. Effective use of this part of gas resources, reduction of gas emissions, and lower production costs are problems that should be solved. Existing power plant boilers are generally pulverized coal boilers or power plant boilers in which pulverized coal is mixed with a small amount of gas.
发明内容Contents of the invention
本实用新型的目的是提供一种利用煤气资源满足冶金企业生产需要，降低生产成本的既能用煤粉又能用煤气的煤粉煤气两用锅炉。The purpose of the utility model is to provide a pulverized coal gas dual-purpose boiler which can use coal powder and gas to meet the production needs of metallurgical enterprises and reduce production costs.
煤粉煤气两用锅炉，其特征在于：该锅炉的燃烧器设有上下布置的两个狭缝式风包气矩形高炉煤气喷口，该喷口在矩形高炉煤气喷口的四周是风喷口，风入口与高炉煤气喷口的截面比是(3-4)∶5；煤粉喷口布置在燃烧器中心，在上层二次风喷口及下层二次风喷口内布置有套管式焦炉煤气喷嘴。The pulverized coal gas dual-purpose boiler is characterized in that: the burner of the boiler is provided with two slit-type air-encapsulated rectangular blast furnace gas nozzles arranged up and down, and the nozzles are surrounded by air nozzles around the rectangular blast furnace gas nozzle. The section ratio of the blast furnace gas nozzle is (3-4):5; the pulverized coal nozzle is arranged in the center of the burner, and the casing type coke oven gas nozzle is arranged in the upper secondary air nozzle and the lower secondary air nozzle.
与现有技术相比，本实用新型的优点是：该锅炉可以全烧煤粉运行，又可以全烧煤气运行，可有效利用冶金企业在生产过程中产生的废气资源如高炉煤气、焦炉煤气，节约能源，降低生产成本，改善环境。Compared with the prior art, the utility model has the advantages that: the boiler can be operated by fully burning pulverized coal and coal gas, and can effectively utilize waste gas resources such as blast furnace gas and coke oven gas produced in the production process of metallurgical enterprises , save energy, reduce production costs and improve the environment.
