Fuel energy storage device in front of the furnace

Can a flue gas recuperator transfer heat to a furnace combustion air?

Since the efficiency of the present recuperator is low, a very large proportion of the flue gas heat cannot be transferred to the furnace combustion air (fresh air).

Can a fuel cell be used as an energy storage device?

When used as an energy storage device, the fuel cell is combined with a fuel generation device, commonly an electrolyzer, to create a Regenerative Fuel Cell (RFC) system, which can convert electrical energy to a storable fuel and then use this fuel in a fuel cell reaction to provide electricity when needed.

How to optimize the combustion system in a furnace?

In the furnaces, the combustion system should be optimized by adjusting the minimum air-fuel ratio that will not cause combustion problems. If the excess air quantity is higher than necessary, the amount of flue gas increases. The increasing amount of air heats up to the flue gas temperature and receives energy.

What is a fuel cell based energy storage system?

A fuel cell-based energy storage system allows separation of power conversion and energy storage functions enabling each function to be individually optimized for performance, cost or other installation factors. This ability to separately optimize each element of an energy storage system can provide significant benefits for many applications.

What is a recuperator in a furnace?

Recuperators are gas-to-gas heat exchangers placed on the furnace stack. Internal tubes or plates transfer heat from the outgoing exhaust gas to the incoming combustion air while keeping the two streams from mixing. Recuperators are available in a wide variety of styles, flow capacities, and temperature ranges.

How can a fuel-fired industrial heating process improve efficiency and productivity?

Published by McGraw Hill Book Company. For fuel-fired industrial heating processes, one of the most potent ways to improve efficiency and productivity is to preheat the combustion air going to the burners. The source of this heat energy is the exhaust gas stream, which leaves the process at elevated temperatures.
