MODEL "D" Solid Fuel Fired
Boiler
 Model
D solid waste fired boiler is one of the most popular
Hamada Boiler series widely distributed throughout
Asian country. During 1976 - 1985 2nd Oil shock era,
when oil fuel shortage hit all industries, many factories
had no other choice but to change their boiler to solid
fuel. Those countries like in the case of the Philippines
where coal fuel was not available, people seriously
thought of using wood/coconut shell as substitute fuel.
Hamada Boiler sold hundreds of wood/cocoshell boiler
of this D model in Manila that time. At the highest
time, as big as one thousand trucks were carrying solid
fuel to Manila from nearby provinces. Model D use fixed
grate with multi air nozzle injection to assure complete
combustion in the large furnace. |

Vertical Water Tube Solid Fuel Boiler
Model LSG series is a very
compact vertical water tube boiler. This model is widely used
by many wood industry for supply of steam to Kiln Dry system.
Water jacketed furnace wall with multi air injection gurantees
high efficiency.
This vertical boiler body can be placed on top of the Fluidized
Bed Combustion chamber for fine coal combustion. We have installed
a small 2 ton capacity of Fluidized Bed Boiler Model LSG2000-FBC
at the energy research center of Indonesia for research and development
activity.

 Fire Tube-Water Tube Combination Boiler
Model RC series is widely
used for small capacity solid fired boiler. Both sides of furnace
are covered by the extended waterwall to receive radiation heat
from the furnace. Large combustion chamber is constructed below
the boiler pressure vessel and the volume of chamber can be flexible
according to the kind of solid fuels to be used. |
