Rocket stove with Flame Pellet Burner, standard not gravity

[stan]

Hello ,I had an idea to combine a standard pellet burner with a riser,

and want to know your opinions about this combination and further installation in a rocket furnace or rocket boiler .

Sorry,the picture is not loaded, although it is small.

At the same time, a construct is seen in which a pellet burner can to be installed into an ordinary rocket stove.

It's not only about comfort, but also the possibility of automation of use .

To organize the pyrolysis of the flame and subsequent afterburning in the riser, I think it is necessary to organize tangential air supply to the bottom of the riser, not far from the conditional channel formed by the pellet burner housing.

Maybe, such combination, together with an appropriate electronic control device with feedbacks on oxygen and flue gas temperature, could work well when using poor quality pellets.

There are also thoughts to use a universal flame burner for pellets, stone fruits and coal-peas.

And here's another ... what if a flame pellet burner is installed in Berg's firebox, and pellets are fired from sunflower husks there?
It will be valid, one hundred percent.
There are constructions in which firewood burns together with a pellet flame  burner. And the rocket will burn.
For example, make a second entrance in the riser, under a pellet flame burner. Let there be a firebox and a pellet burner.

If you are going to use control devices which I assume includes fans, then I do not think you need to use the rocket stove riser at all.

The design of the rocket stove is to insure complete combustion using sticks and natural draft. If you have an auger to feed a small amount of pellets (seeds, etc) onto a crucible where a fan blows the exact amount of air to combust them, you do not need a rocket stove, as far as I can see. donkey32.proboards.com/post/new/3790

I assumed there would be similar opinions.
Natural vacuum in the firebox is good, but to burn mediocre quality fuel,in special pellets, gas velocities and unburned partice pirolisation of fuel in the flame are needed.
The riser, due to its design, in my opinion, is quite suitable for these purposes.

[stan]

The chemical composition of the flame is highly unstable and inconsistent over time.

In addition to incandescent gases, there are also aerosols and simply carried away, non-pyrolyzed particles of solid fuel.

This is of course the basic premise of the experiment.
The second is the exclusion of wood slavery, it is one thing to contemplate the burning of wood in a firebox on weekends, and another thing to be a stoker near the boiler.

For example, I am a working man, and I need warmth and hot water in the house, without involving my beatiful half in this process.

I think that you need to do a little more reading about rocket mass heaters especially the bit about mass .

[stan]

I understand what you mean, so I'll clarify.
This is a so-called rocket boiler, not a rocket furnace.

I too am interested in this idea. I have both a pellet stove and a batch box rocket mass heater. I love the ease of operation of the pellet stove, but I've wondered if more heat could be reclaimed from the burn by passing the pellet stove exhaust gases through a masonry bell before sending it out the chimney. If the metal box and blowers suck all the heat out first, then there wouldn't be any value. I guess I'll have to put a temp gauge on the pellet stove's chimney at the roof this week an find out.

[stan]

The amount of heat per unit of time depends on the number of units of fuel burned per unit of time.

But that's not all ... Air, it needs about 9m3 per 1 kg of fuel. The flue gas removal system of the apparatus must be designed taking into account these requirements.

The nuance of using a pellet flare burner is the blower .

What will be the value of CO in this case, because solid fuel goes through three phases of combustion in any case?

CO value measured in exhaust flue gases characterizes combustion with sufficient accuracy.

I think that measuring the parameters cannot be avoided, and it is rather difficult to navigate process by eye, this is not the case.

[stan]

Its possible different stage. For example
Fuel in the firebox can be in the gas generation mode, it controls the process and, in particular, the blowing can to be controlled of the pellet flame burner.

[stan]

I want to clarify, in a pellet burner one of the work modes, possibly pulsed detonation combustion.

I started a tread about this guy in this youtube vid tries making some CO with pellets in a beaker with a blower. It starts around 6 minutes in but gets really good about 7:30ish.

I think the take away from the video is not the CO effort but the really good burn with the coal tornado inside the beaker. Its a fun watch;

Thanks for the interesting video, I haven't seen it.

My idea is somewhat different, I want to separate the gasifier and burn the gases in the riser using flameless combustion .
