The present invention relates to a process and an apparatus for utilizing fossil energy with low carbon emissions, which belongs to a technical field of clean energy and climate mitigation. The present invention is applicable for utilizing fossil, biomass and other carbon-containing fuels in coastal and marine areas to produce clean energy with low carbon emissions to atmosphere and low cost. The process comprises the main steps of carrying out the oxygen enriched combustion and using seawater to scrub the flue gas once to realize carbon capture, and the scrubbing water is recovered to a water quality in accordance with legal requirements and then is discharged into the ocean to realize carbon storage of ocean natural alkalinity, so that the resources of carbon sink and carbon pool in natural ocean are used to reduce greenhouse gases in the atmosphere in a safe and environment-friendly form.

The present disclosure seeks to provide a metallic burner tile for use in industrial processes such as cracking. The tile is substantially metallic (e.g. more than 80%) with the balance being ceramic coating on surfaces exposed to high temperature. The tile is lighter and more durable than the current ceramic burners.

A forehearth system includes a superstructure including refractory bricks that frame a molten glass tank, with a burner block including a discharge throat that extends its distal end formed from a refractory material that is within the superstructure above the molten glass tank. At least one oxygen fuel forehearth burner is within the burner block including a burner body, a fuel pipe within the burner body having a fuel inlet for receiving fuel and a fuel outlet, and an oxygen pipe within the burner body having an oxygen inlet for receiving oxygen and an oxygen outlet. The oxygen pipe is positioned coaxially outside the fuel pipe. The fuel outlet extends beyond the oxygen pipe and beyond the burner body so that the oxygen first reaching the fuel and thus a flame when operating is delayed until the discharge throat.
