[Stoves] Stove testing in Mongolia continues

[M. Nurhuda]

Dear Crispin and all,

Three years ago, I developed a formula for coal briquettes and pellet that
are easy to light and provide good flame instead of radiant heat. Typical
flame is pink-transparent, depending on used additive to convert the
radiant heat to flame. Latter, I learned that coal pellet is better than
coal briquette.

The feedstock is low grade coal, which is abundant in Mongolia. Please

Kind regards

> Testing has restarted at the SEET lab after a major move to a new location
> at the Mining Research Institute north of the city. An announcement was
> made
> in the newspaper asking for stoves to be brought to the SEET Lab. The
> following criteria are listed:
>
>
>
> 1.       Stove should have a name, a type and manufacturer clearly stated.
>
> 2.       Drawings supplied
>
> 3.       It should be well sealed and have controllable air (meaning power
> level)
>
> 4.       Must be serviceable for both heating and cooking (cooking means
> heating a single large wok)
>
> 5.       Easy to light, must not require the use of gas cylinders (little
> butane blow torches)
>
> 6.       Fuels to be uses: coal, semi-coked briquettes and wood
>
> 7.       Manufacturer must be able to explain how to ignite it
>
> 8.       If the stove is provided by an importer, the importer must have
> both an importer's licence and a contract with the supplier assuring
> supply.
>
>
>
> The testing will be conducted immediately the stoves arrive. If there are
> too many for the lab they will be pre-screened using portable testing
> equipment by specialists at the Ulaanbaatar City Air Quality Department.
>
>
>
> The evaluation metrics are:
>
> -          Ignition method (ease and convenience)
>
> -          Thermal efficiency as a space heater of more than 70% (Siegert
> Method)
>
> -          Average heating power of >3.83 kW (net)  [This is the same as
> 5.5
> kW @ 70% efficiency.]
>
> -          PM 2.5 per net MJ of space heating energy (PM2.5/MJ(Net))
>
> -          CO per net MJ of space heating energy (CO/MJ(Net))
>
> -          Average CO/CO2 ratio
>
> -          NOx SOx and H2S (mg/MJ(Net))
>
> -          Safety considerations
>
>
>
> Power and emissions are considered after 90% of the initial mass of fuel
> has
> burned.
>
>
>
> Several stoves have arrived including 3 TLUD's (which are the most
> popular)
> and one that lights as TLUD and converts automatically to a side-fed
> up-draft configuration. The TLUD's are based on the Silver stove from
> Turkey
> and includes a brand new unit that looks in shape a lot like a Kimberly
> Stove. The converting one is based on many of the design features of the
> GTZ-7 described previously on this list. It may prove to be the first coal
> stove ever built that has net negative PM emissions. All the high end
> stoves
> scrub PM from the ambient air emitting less than they take in, but only
> after they have heated up significantly which takes about 15-20 minutes.
> We

> The test method is the SeTAR HTP v3.044 which provides real time emissions
> and thermal performance.
