Problems solved by technology

However, carbon dioxide is a problematic product, because emissions of it contribute to the greenhouse effect.
On the other hand, impurities in carbon dioxide containing gas slow down the growth of plants.
The strict standards for purity of CO2 hinder the application of gas produced in thermal combus

Abstract

A method and apparatus for producing very pure carbon dioxide containing gas and thermal energy and the use of such apparatus and method are described. The production apparatus (PA) includes at least one catalytic combustion unit (2) with at least one catalytic burner (NCB) for catalytic combustion of fuel, for burning the fuel efficiently at a temperature of 350 to 850° C. in a retention time of 0.01 to 0.1 s, and at least one heat exchanger (RHE, THE) for at least partial transfer of heat from the gas (CO2G) formed in the combustion to the combustion air (AIR) and the fuel (PG) to be supplied into the catalytic burner (NCB). The production apparatus (PA) also includes at least one catalytic after burner (ACB) for at least partial after purification of the gas (CO2G) formed in the combustion.

Description

TECHNICAL BACKGROUND[0001]The invention relates to an apparatus for producing very pure carbon dioxide containing gas and thermal energy. The invention also relates to a method for producing carbon dioxide containing gas and thermal energy, as well as the use of such an apparatus and a method.[0002]Carbon dioxide can be used for a number of purposes. It can be directly applied in various uses, and on the other hand, it is suitable as a raw material for many processes. However, carbon dioxide is a problematic product, because emissions of it contribute to the greenhouse effect. Therefore, the controlled production of carbon dioxide is of primary importance.[0003]In atmospheric air, the content of CO2 is about 380 ppm. When plants are grown in a greenhouse, the content of CO2 will drop to a level of about 150 to 220 ppm if no supplementary CO2 is added. At a level of about 800 ppm, the growth of, for example, cucumber, tomato and lettuces, as well as tulips, has been found to increase...
