The " Player stove " was provided at its base with a large 

 "combustion chamber" (see Fig. 35), into which the gas entered, 

 and there meeting with sufficient air for its combustion, the re- 

 sulting heated gases passed upward through flues (indicated by 

 the arrows s, s, s) in the roof of the " combustion chamber " into 

 the " pipe chamber " above. In this chamber were arranged a 

 series of vertical " siphon pipes," standing upon hollow bases or

bed pipes " of cast iron. The air to be heated was admitted to 

 the right-hand bed pipe B (Fig. 36), and passed thence in the direc- 

 tion of the arrows through the siphon pipes into the left-hand 

 bed pipe B', from one end of which it was taken in suitable pipes 

 to the furnace. The introduction of the " Player stove " was the 

 means of greatly increasing the production of iron in the furnaces 

 to which they were applied, and at the same time the amount of 

 fuel required per ton of iron was diminished ; further economies 

 were realized by increasing the size of furnaces, and the power of 

 the engines that supplied them with blast. 



The first example of the second type of hot-blast stove erected
