SUMMARY:Performance and recently orders of top combustion type hot stove with metallic burners
DESCRIPTION:One of the effective ways to decrease coke consumption and reduce CO2 emissions is to increase the blast temperature, but SCC caused by NOx and limited heat resistance capability of checker support lead to limits in dome temperature and waste gas temperature, respectively and therefore maximum blast temperature is, in general, 1200℃. NSE developed low NOx burner and new checker support so that the temperature at dome can be increased by 30℃ and waste gas by 100℃, allowing higher blast temperature. In addition, downsizing reduced initial cost of the new or modification of hot stove. We have delivered 5 units of this type of hot stove to large blast furnaces in Japan, and they are currently in stable operation.
Furthermore in combination with our Waste gas Heat Recovery System（WHRS）for Hot Stove, further reduction CO2 emissions can be realized. 
Our WHRS is of heat medium circulation type, and has characteristics that enable to control the recovered heat and also provide the flexibility to install the heat receiving unit and heating unit separately, resulting in advantage of ①High efficiency of heat recovery, ②High layout flexibility ③Easy maintenance.
In this paper, we describe the performance and recently orders of this equipment.
