Wood Furnace Blowers and Fans When a furnace stops working, there are many parts including blowers that could have gone wrong. With so many moving parts inside of the unit, the only way to diagnose the problem is to look at it and check a few things, or get a qualified repairman to do the job instead for a small fee.
the furnace may burn these unburned gases, but elimina-tion of the causes of incompletely burned gases being formed will help greatly to produce a clean stack. To illustrate, Figure 1 shows the fire on a chain grate stoker. This photograph was taken through an inspec-tion door in the rear corner of the furnace. The coal was

Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.
Old wood burning fireplaces may have been blocked off and coal stoves had been piped into the old chimney flues. Some buildings still have their original coal fired boiler or furnace, but it has been converted to fuel oil or gas. In many 19th century homes, an old abandoned chimney used to serve a coal cooking range in the original kitchen.

There is a lot of talk in Australia and New Zealand about Duplex steel boilers (i.e. boilers constructed using a boiler grade stainless steel instead of carbon steel or copper). The big advantage of the use of this material is the wall thicknesses can be about 1/2 as thick.
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
The coal-feed hopper runs along the entire coal-feed end of the furnace. Acoal grate is used to control the rate at which coal is fed into the furnace, and to control the thickness of the coal bed and speed of the grate. Coal must be uniform in size, as large lumps will not burn out completely by the time they reach the end of the grate.
