Fuel Savings for Slab Reheating Furnaces through Oxyfuel Combustion
نویسندگان
چکیده
With high fuel prices, fuel-savings technologies can provide significant economic benefits to steel mills. Reheating furnaces in integrated and mini-mills consume approximately half of the natural gas used to produce hot-rolled products. Recently, Praxair’s Dilute Oxygen Combustion technology (previously demonstrated for productivity improvements on mini-mill billet reheating furnaces) was extended to a slab reheating furnace. This flexible oxyfuel combustion system delivered significant fuel savings with no impact on other critical process parameters (steel surface quality, emissions, refractory, oxide scale, etc.) This paper reviews installation, startup, operating results and plans for installation on other slab reheating furnaces in the hot strip mill.

Numerical Model of Steel Slab Reheating in Pusher Furnaces
The difficulty in measuring load temperatures inside reheating gas furnaces may be circumvented by appropriate use of on-line numerical models. In this article we describe a model of pusher furnaces, used to reheat steel slabs. The model uses thermocouple measurements at fixed positions inside the furnace to calculate the temperature of the combustion products, and takes into account radiative ...
متن کاملA mathematical model of a slab reheating furnace with radiative heat transfer and non-participating gaseous media
Amathematical model of the reheating process of steel slabs in industrial fuel-fired furnaces is developed. The transient temperature field inside the slabs is computed by means of the Galerkin method. Radiative heat transfer inside the furnace constitutes boundary conditions that couple the dynamic subsystems of the slabs. Constraining the heat fluxes to piecewise linear, discontinuous signals...
متن کاملEnergy Efficient Process Heating: Managing Air Flow
Much energy is lost through excess air flow in and out of process heating equipment. Energy saving opportunities from managing air flow include minimizing combustion air, preheating combustion air, minimizing ventilation air, and reconfiguring openings to reduce leakage. This paper identifies these opportunities and presents methods to quantify potential energy savings from implementing these e...
