This is the first boiler we introduced and it has proven to be a fast steaming, reasonably light weight, safe, and reliable unit. It is especially suited to boats which are to be transported by trailer. It will provide enough steam and at the appropriate pressure for the 5 HP Compound or 7 HP Triple engines. It incoporates accepted professional boiler design principles. For oil firing we suggest our steam atomizing burner design - listed on the ACCESSORIES page.

The Roberts style watertube boiler has been proven through many years of service. As a woodburner, this boiler is unexcelled in performance. Its large capacity steam drum and ease of firing makes steaming with solid fuels a real pleasure. The design is to professional boiler standards.
 


 


Monotube Boiler

15 - 40 HP  Monotube Boiler
 
Horsepower............................ 15 - 40
Rated Working Pressure......... 600psi

This is a very robust monotubular steam generator design. A series of helical coils of increasing diameters are placed one inside the other and connected, alternately at the top and bottom, thus preventing flooding of the coils - a problem on many monotube steam generators. The bottom of the firebox consists of an economizer coil so that a maximum of heat absorption is obtained. The design is to A.M.S.E. boiler power code. The 15 HP uses our design of steam atomizing burner - listed on the ACCESSORIES page.
 


 


Monotube Boiler

50 - 125 HP  Monotube Boiler
 
Horsepower.......................... 50 - 125
Rated Working Pressure....... 1000psi
Heating Surface................... 80 sq.ft.
Weight, dry........................... 350 lbs.
Overall..................... 36" dia. x 28" H
Firing............... Fuel Oil or Kerosene

PLANS: BR.05
pdf  file $ 40

A modification of the 15 - 40 HP, BR.04, unit above. The heating surface has been substantially increased. This results in the coils being somewhat closer together with resultant need for larger and more powerful burners. The design is to A.M.S.E. boiler power code. We suggest that a water separator/scale trap be used. We offer plans on the ACCESSORIES page.
