Introduction. In the opinion of world expert association, the global warming of boundary layer within the system of “Earth’s surface — ambient atmospheric air” has been caused by the effect of carbon-containing components (mainly CO2) referred to as greenhouse gas (along with H2O) and by the redistribution of radiative heat fluxes
within the environment.
Problem Statement. The principal sectors of economics influencing upon the greenhouse gas emission include an industry, electric and heat power generation, means of transport. However, in the Ukrainian conditions, the municipal and household gas supplying sector is of special significance given the structure and the main constituents of the national fuel balance, particularly in the case where a reduction in CO2
emissions is attained by carbohydrate fuel substitution with hydrogen.
Purpose. The purpose of this research is to determine the opportunities for safe operation conditions and the prospects for natural gas substitution with hydrogen by supplying household gas-powered appliances (HGA)
with mixed fuel and to experimentally study the feasibility (efficiency) and HGA environmental characteristics (harmful gas CO and NOx emissions).
Materials and Methods. The problem of environment decarbonization nowadays has been solved by substitution the natural gas (NG) with NG (methane) blended with hydrogen. The household gas devices: RÖDA heating boiler (Germany) and GRETA gas cooker stove (Ukraine) have been tested in terms of combustion of the MG (air mix containing up to 50% (vol.) [H2]) as compared with pure NG.
Results. The moderate impact of [H2] content in fuel gas in terms of power and environmental characteristics of HGA by varying the [H2] fraction within the range of [H2] = 0—50% (vol.) has been stated.
Conclusions. For the first time, the theoretically predicted possibility of safe operation of HGA with the use of methane-hydrogen mixes with [H2] content up to 50% has been experimentally proved. The boiler efficiency in terms of fuel consumption grows with increasing heat capacity, in contrast to the extreme dependence of the gas
stove efficiency on heat capacity.
