best rocket stove design for grilling and boiling?

Hi, I am interested in building a rocket stove for outside that I can use for grilling food in the summer, and also for boiling maple sap in the winter/spring.  what would be a good design that would be condusive to that?  also, are red clay bricks sufficient?

To answer your last question first: No, red clay bricks will not endure the temperatures of a rocket stove burn chamber.

Boiling maple sap is a long process, so your best option is a Batch Box. You are going to need skilled, experienced, help to get one right the first time, as they are complex. They can provide several hours of continuous high temperatures.

Oh boy.  Well, I guess a rocket stove is out of the question.  I can't build it myself. At least now I know.  Could the red clay bricks work for a grill at least?
