There are two main types of smoke alarms, and both detect all types of growing fires: Ionization alarms, which sell for about $5 for battery-operated models, respond faster to flaming fires, such as those involving paper or flammable liquids. Photoelectric alarms, which sell for about $20, respond faster to smoldering fires, such as those
A method of operating a furnace having a circulating fluidized bed is described. Fuel is combusted in the fluidized bed. The fluidized bed includes a dense bed portion and a lower furnace portion adjacent to the dense bed portion. Reactant is injected in the furnace to reduce the emission of at least one combustion product in the flue gas.
Gas Furnace Ignition Control Operation | HVAC Heating. There are gas furnaces that use various types of controls for ignition. Part of every ignition operation will include a safety check built into the logic of the board or module. The safety check is basically a series circuit that runs through several switches. Some switches are always closed.
