Photos ökofen pellet boiler: installation and storage

Here are the pictures of his heating system (boiler, burner, storage silo and delivery of pellets) Pellets (pellets of wood) that had sent me Did67. I leave it to him to comment on his installation in more detail.

Comments are indicated by Did67 below.

ps: if you want to see another installation, here is a complete file on pellets: Heating by Pellet boiler, know everything

Voila!
That's "all" (don't laugh! I still spent an hour processing the images and putting them on the forum!), I warn did67 of this posting and do not hesitate to ask your questions. He will answer it better than me for sure!

Hi,

so I have a question : Cheesy: I would like to know what is the purpose of the dust collector, because I do not have it on my installation?

Good night. Hélène

First of all, hello!

The vacuum cleaner is the delivery man who provides it. Otherwise, Okofen provides a kind of big "sock". And that is why it is necessary to put two connectors: one in the middle to blow the pellets, the other on the side to collect the dusty air without sucking the pellets.

The utility is simple: the pellets are "blown" from the truck by a large volume of air; this air is charged with dust; air must be evacuated from the silo while retaining dust; my supplier therefore uses this kind of large vacuum cleaner.

I'm not sure, but I suppose moreover that the vacuum cleaner extracts more air than the truck blows and so the silo is slightly depressed (so even if it was not completely waterproof - mine is), this would prevent the dust invades the premises ...

Kikou : Cheesy:

ok thank you I understand better. So I do not need it because our firefighter connections are on the outside in the yard and when the driver came dust left .... outside : Cheesy: good just do not forget to close the windows of the car or the house : Mrgreen: : Mrgreen: : Mrgreen:

In any case nice installation Didier.

Me I'm not going to say that I wait for the winter with impatience (it would be silly considering that had a rotten summer here) but I would like to see my boiler en route.

In any case for now solar is turning and we are happy.

kisses. Helena

Effectively.

I always remember that I do not advertise a given brand. For specialists, I remind you that this is a PESK 15 (condensing) from Okofen. The 1st photo also shows the condenser, "grafted" on the boiler, before the gas leaves in the chimney: the gases are "blown" downwards by a fan, against the flow of cold water return. The "washing machine-style hose" is the exchanger rinsing system (two automatic rinses per day).

The interest of these photos is to show details usually hidden because the installer had to disassemble the boiler to invert the silo-relay and enter local and luckily I was off work (well, by bad luck: following an infarction!).

I will comment as soon as Christophe tells me how to do it.

And I am always ready to answer all the questions, and to supplement with other photos, which can specify a detail, according to the interest of each one (either on the wire, or by mp).

It's good you have instructions by MP.

A) Delivery of the boiler and assembly

Image

rear of the boiler, with the condensation system: the kind of toothed ring at the top, around which the black electric cable is wound = end of the fan motor which pulses the exhaust gases downwards; at the bottom: outlet of the "suction cup" for gas evacuation / outside air supply (for the case of a suction cup assembly); below, just above: connection for cold water return (against the flow of gas); the large gray pipe like an electrical sheath placed in a loop = protection of the water connection for rinsing, with solenoid valve to screw on the tap ...

Image

Start of reassembly in place: the condenser at the back is in place and covered with its hood: on the right, we guess the map and all the embedded electronics; in the center, the body of the boiler under its insulation; the pellet feed is not yet in place (rectangular opening at the bottom)

Image

The silo of the boiler is in place; hoods were handed over; at the bottom, we see the chain leading to: a) the pellet dosing system at the base of the silo; b) the screw that will convey the pellets into the burner ...

B) Details on the burner

Image

The Okofen "volcano" burner (seen from above): in the middle, arrival of the pellets; two air inlet pipes (pulsed by a variable fan controlled by the computer); at an angle: the thermal probe for ignition (like a heat gun); above: the outlet of an air supply pipe for the post-combustion of the combustion gases (supplies the space around the burner) ...

Image

The "Belimo" safety valve control system: closes automatically in the event of a problem (including in the event of a power cut: closing activated by a spring, therefore energy stored; opening requires current); prevents any "flashback" to the boiler silo in the event of an anomaly such as a power cut ...

Image

Detail on the safety valve (identical to a large stainless steel 1/4 turn tap) in the center; the "pan" on the left = the variable power fan

Image

Fan detail

C) Heat exchanger with cleaning springs

Image
Detail on the body of the boiler, without cover, seen from above; with the "turbulators" in which the gases circulate; the springs create turbulence for better heat exchange with the water circulating in the crown; they are animated once a day to release the soot that settles (automatic cleaning - one motor for all the springs + compacting of the ash in the ashtray); we see on the right and on the left, pipes closed by a welded plug (= clamping, to reduce the power to 15 kW, from the "bodywork" of the 20 kW).
