With the increase of 25°C in combustion air, the combustion efficiency will increase by 1%.
Product Introduction
As we know, the most part of energy produced in combustion reaction exits from stack. The temperature of stack depends on heating efficiency system (like heat exchanger, boilers … etc.) and the operation temperature. For example, the operation temperature of hot oil reaches up to 3000°C, which can be used to reduce energy consumption. There are different approaches to recovery energy in variable systems. One of these approaches is to preheating of combustion air, which has considerable effect on combustion efficiency and its operation. In this way, not only is energy loss recovered, but also it causes less amount of pollution.
Recuperator is a gas-to-gas heat exchanger in which air combustion is preheated by exit gases. In addition, with the increase of 25°C in combustion air, the combustion efficiency will increase by 1% as the boiler efficiency will rise by 3-6%.
With preheating the air combustion, boilers’ life expectancy, or any kind of heat exchanger, which operates with flame, will increase and the percentage of CO and NOx emission will reach international standard level.
According to the fact that the Recuperator is not pressurized and the inlet air temperature is under 400°C, its life expectancy is twice that of heat exchanger and fatigue under any operation condition of boiler is almost impossible.
The cost of installation a Recuperator, which its capital cost compared with that of boiler is negligible, will retrieve in a short time, and result in significant decreases in energy consumption.
Recuperators can be installed in the following heat exchangers and heating systems:
• Different kinds of industrial furnace: steal stress reduction, preheated steal furnace, brick furnace, glasses furnace and any industry in which exit air from stack is at up to 200°C.
• Steam boilers with the capacity of up to the 5000 kcal/h
• Hot waterboilers with the capacity of up to the 2000 kcal/h
• Hot oil boilers in any capacity.
