USE IN COMBUSTION PROCESSES FOR A NEW TYPE OF GASEOUS FUEL BASED ON HYDROGEN

摘要

The paper approaches a very actual problem worldwide, concerning the replacing, in combustion processes, of classical fossil fuels by clean energy sources, in order to reduce the greenhouse effect gases, as well as for fossil fuels' saving. The experiments aimed to obtain an oxy-hydric gaseous fuel, known as HRG gas, resulted by a new procedure of water electrolysis, in a generator conceived and realized in USA and improved in Romania by the company Rokura Industrial Applications, which is, in the present, the owner of licence to apply this fuel in Europe and Israel. The HRG gas contains hydrogen and oxygen in approximately equable proportions and its structure is different of that molecular conventional, conferring its particular properties. The tests effectuated until now have bringed the HRG gas combustion in association with natural gas and air, the mixture being realized in the combustion area, by injection of HRG gas directly into the flame. In accordance to the experimental results obtaining, the intensification of combustion process allows the reduction of natural gas consumption by 14.7%, in the conditions of obtaining the same thermal effect that in case of combustion only of the natural gas. Also, the partial substitution of natural gas with HRG gas conducts to important decrease of CO proportion in waste gaseous. When the substitution increase more than 20%, the emissions of CO are reduced almost close to zero.
