commercial and residential building space. Fuels typically used in boilers include coal, oil, and natural gas. In addition, liquified petroleum gas (LPG), process and waste gases, and wood wastes may be used. In general, boilers are categorized as follows: Types of Boilers Size Utility >100 MMBtu/hr Industrial 10 - …

The flow rate of the input gas must also be adjusted to take care of the fact that hydrogen is much less dense than natural gas but has a higher calorific value. Emissions of NO x may be slightly increased initially, but optimizing the flow rate and the introduction of boilers dedicated to hydrogen use should solve this problem, whereas carbon

Boiler Safety

With the boiler pressure at a minimum of 75% of the safety valve set pressure, the safety valve try lever is lifted to wide open position. Steam is discharged for 5 sec to 10 sec. The try lever is released, and the disk should snap to the closed position against the valve seat. Malfunctioning safety valves must be replaced as soon as possible.

When evaluating the prospect of converting a coal-fired boiler to natural gas, there are a number of factors that need to be independently evaluated. The combustion system modifications and air and flue gas flow rates, heat transfer through sections, boiler efficiency, attemperator flow, and tube metal temperatures. This paper will address

that of natural gas. Therefore, the volume of LFG that must be handled by the fuel train and burner is twice that of natural gas. This means that modifications to the fuel train and burner are usually required to accommodate the higher overall gas flowrate for an equivalent natural gas heating value. The increased gas flow, however, does not
