A regenerative combustion system

Abstract

The invention discloses a regenerative combusting system which comprises at least two regenerative combustors arranged on a kiln, an air supply system, a fuel supply system, a smoke exhausting system, a continuous flame system and a reversing system, wherein each regenerative combustor comprises a regenerative chamber which comprises an upper regenerative chamber and a lower regenerative chamber, a front buffer chamber and a rear buffer chamber are arranged at the front part and the rear part of the regenerative chamber; the front buffer chamber and the rear buffer chamber are separated by the upper regenerative chamber and the lower regenerative chamber; the rear buffer chamber is connected with the air supply system and the smoke exhausting system respectively; a fuel cavity is formed between the upper regenerative chamber and the lower regenerative chamber and connected with the fuel supply system; the fuel cavity is communicated with the hearth of the kiln; an air distributing plate is arranged between the front buffer chamber and the hearth of the kiln; a continuous flame burner hole, a fuel spray nozzle hole and an air distributing hole are formed in the air distributing plate. The regenerative combusting system is long in service life, stable in work, high in heating efficiency and obvious in energy saving and emission reduction effect.

Description

technical field [0001] The invention relates to a regenerative combustion system. Background technique [0002] With the continuous development of my country's economy, the pressure on resources and energy is increasing, and economic transformation and industrial restructuring are becoming more and more urgent. For industrial technology, it is our inevitable choice to take the road of resource-saving and environment-friendly sustainable development. In my country, industrial furnaces are large energy consumers, and the energy utilization rate is generally low (about 20%), and the average unit consumption of products is about 40% higher than that of developed countries; Waste heat has not been well utilized; at the same time, the potential for energy saving and emission reduction of industrial furnaces is also huge. [0003] The energy saving and emission reduction methods of industrial furnaces mainly include the following aspects: [0004] 1) Improve the combustion effici...
