Natural gas is used as a boiler fuel in gas well regions where fuel is relatively cheap and coal sources comparatively distant. The transportation of natural gas over land to supply cities with domestic and industrial heat has made the gas in the well more valuable and the gas-fired steam generator more difficult to justify in comparison with coal, or fuel cost alone.

A Hydrogen co-production through synthesis gas formation from coal (primary steam) and high temperature steam electrolysis is employed (secondary steam). The product of combustion of hydrogen in steam boilers along with the stream from the steam drum is used to run the turbines. The outlet steam from the turbines instead of being condensed is

Feb 17, 2016 · Boilers and burners require a combustion analysis on a regular basis for proper operation. The combustion analyzer measures the air-to-fuel ratio of the burner and calculates the efficiency of the boiler. The analyzer also may display the emissions output from the boiler. Each cubic foot of natural gas burned produces: 8 cubic ft. of nitrogen;

– Flue gas from the outlet of the boiler is mixed with the combustion air to the burners. – FGR reduces the combustion temperature and lowers the localized O2 concentration in the primary combustion zone to achieve a reduction in NOx. – Increasing the flue gas flow through the convective pass of the boiler increases heat transfer.
