Traditionally, Multi-Fuel boilers have been sold as wood/coal combinations. Due to EPA regulations, and no EPA Phase 2 approval for the the Multi-Fuel updraft units, they are sold for use with coal. When starting a new fire in the Multi-Fuel boilers, wood is the fuel of choice.
Pulverized fuel boiler: Coal is pulverized into a fine dust (about 0.1 mm in size), and is fed into the boiler in a stream of air. They are by far the most common boiler types for coal. These boilers can reach efficiencies of over 90% when they are well run. They can be co-fired with wood or other suitable fuels as well.
The Small Boiler NSPS apply to all new, modified, or reconstructed boilers with inputs between 10-100 MMBtu/hr where construction, modification, or reconstruction commenced after June 9, 1989. The Small Boiler NSPS set emission standards for SOx and particulate matter for boilers firing coal, distillate and residual oil, and wood.
Natural gas-fired boilers may run as low as 5 percent excess air. Pulverized coal-fired boilers may run with 20 percent excess air. Gas turbines runs very lean with up to 300 percent excess air. Typical values of excess air for some commonly used fuels are shown in the table below:
