Efficient Process Heating - Energy

Heat Generation Control air-fuel ratio.Proper adjustment of the air-fuel ratio can cost-effectively reduce energy use by 5-25%. Operation with too little air allows incomplete combustion, wastes fuel, and emits CO and unburned hydrocarbons (UHCs). Too much air dramatically increases the volume of waste heat in …

Energy Audits for Thermal Oxidizers, Furnaces, Ovens & More

Our original air-fuel ratio control technology per each individual burner is a control system that can adjust individual burner combustion in response to the every changing situation. Particularly, in regenerative burner control, it can reduce oxygen level in the furnace as well as power consumptions of combustion air blower and exhaust induced draft fan.

Understanding burners for heat-treating furnaces

Air/fuel ratio is typically controlled with differential pressures from an ori fi ce plate in the combustion air line and a fl ow-based fuel rate control system--either regulator or electronic. Typically, about 80% of the furnace gases are exhausted through the regenerators. The remaining 20% passes through a pressure controlled furnace fl ue.

Combustion System of a Reheating Furnace – IspatGuru

Jul 01, 2015 · The air-to-fuel ratio is typically set with the intention of producing a desired level of excess oxygen in the flue gas. The objective is to ensure that all the fuel is combusted within the reheating furnace but at the same time to avoid excessive combustion air …

Improving Thermal Efficiency in - Industrial Heating

Oct 01, 1994 · Local gas temperatures, local concentrations of major gas species and incident wall heat fluxes were measured in a large end-port, fuel-fired regenerative furnace for manufacture of glass containers, with a nominal output of 90 t d −1 of soda-lime glass and a specific energy consumption of 5.9 GJ t −1. Two different operating conditions were studied to investigate the effect of furnace throughput and air:fuel ratio on the heat …
