Direct co-firing is a simple approach and the most common and least expensive method of co-firing biomass with coal in a boiler, usually a PC boiler. As shown in Fig. 4.1, in direct co-firing technology biomass is fed directly into the furnace after either being milled together with the base fuel ( Fig. 4.12A ) or being milled separately ( Fig. 4.12B ) The fuel mixture is then burned in the burner.

Boiler inspections are mandated to be carried out in states and municipalities having boiler safety laws. These are called jurisdictional inspections. In most states these laws call for inspection of water-side systems (water level controls and pressure-retaining devices), but not testing of fuel train safety devices.

Where coal was readily available (i.e. the anthracite coal region in northeast Pennsylvania) coal-fired steam or hot water systems were common. Later in the 20th century, these were updated to burn fuel oil or gas, eliminating the need for a large coal storage bin near the boiler and the need to remove and discard coal ashes.

For hotel heating enterprises that do not supply steam for industrial production but only provide heating for residents, the first choice is the hot water boiler as the heating boiler. Because the operation of hot water boiler is safer, more stable and more economical than regular boiler, meanwhile, the heating radius of hot water is about twice that of steam, and the maximum heating radius can reach 20 km.
