Title
(EN) SYSTEM AND PROCESS FOR HYDROGEN COMBUSTION
(FR) SYSTÈME ET PROCÉDÉ DE COMBUSTION D'HYDROGÈNE
Abstract
(EN) The invention relates to a system and process for hydrogen combustion for industrial or steam generation applications, and more particularly to a hydrogen combustion burner or retrofit kit combustion system and process using a primary pure hydrogen fuel source. The burner or retrofit kit combustion system and process may also use one or more secondary fuels, such as natural gas, methane, propane, or the like, to reduce emissions of CO2. Additionally, the inventive burner, system and process can use a flame temperature reducing fluid for lowering the bulk flame temperature of the burner to increase equipment life and decrease equipment failure. The flame temperature reducing fluid can include flue gas recirculation (FGR), water injection, steam injection, and a combination thereof.
(FR) La présente invention concerne un système et un procédé de combustion d'hydrogène pour des applications industrielles ou de production de vapeur, et plus particulièrement un brûleur à combustion d'hydrogène ou un système de combustion de kit de rattrapage et un procédé utilisant une source de combustible à hydrogène pur primaire. Le brûleur ou le système de combustion de kit de rattrapage et le procédé peuvent également utiliser un ou plusieurs combustibles secondaires, tels que le gaz naturel, le méthane, le propane, ou analogues, pour réduire les émissions de CO2. En outre, le brûleur, le système et le procédé selon la présente invention peuvent utiliser un fluide de réduction de température de flamme pour abaisser la température de flamme approximative du brûleur pour augmenter la durée de vie de l'équipement et diminuer la défaillance de l'équipement. Le fluide de réduction de température de flamme peut comprendre une recirculation de gaz de combustion (FGR), une injection d'eau, une injection de vapeur, et une combinaison de celles-ci.
