BIOMASS FURNACE (ENGLISH VERSION)

Dimension Of Biomass Furnace

Part name of Biomass Furnace

Work System of Biomass Furnace

Type of Biomass

Biomass to Energy
I design a system which makes a low-calorie of biomass capable of producing a high heat of combustion. I know that the biomass has a low calorie compared to coal, but we focus on how to perfect combustion, I researched everything was burned to perfection it will generate:
1. high heat
2. less smoke generated
3. Less fuel.

paper Sludge

Biomass that had us use one of the examples below are:
1. Paddy husk
2. dried leaves
3. Paper sludge
4. the Straw
5. corn Straw
6. Jangle corn
7. wood shavings
8. coconut fibers
9. coconut shell

10. Palm shell

Each material has been tested and was burned in the biomass furnace.

coconut Shel

Dried Leaves

No need tobe formed as a pellet, can be in bulk form, to reduce the cost of fuel costs.

Wood Shavings

In the Normal condition, with 5 sack / hour, 1 sack = 15 kg of dry biomass, producing heat is very stable in heat output of more than 1400 C. Biomass consumption when added to the Heat Output Increases, Biomass consumption decrease When the Heat output is reduced as well. And consumption of biomass input is adjusted automatically to maintain the stability of Heat Output.

Daily running hours? Yearly running hours?

Daily running hours?
Daily running this biomass furnace is 24 hours and 7 days a week. The use of biomass furnace stopped only 3 days of each end of the month for the replacement of spare parts. In Indonesia there are many companies that use biomass furnace over the daily running hours, although it should work on a Sunday or holyday.
But normally Biomass furnace has a Daily running hours 24 hours / day, 5 days /week. 2 days for treatment
.In Indonesia, is even worse, our observations since 2007, Biomass Furnace is widely used over-capacity, in the year just stopped 2 times for maintenance and repairs, and it only took 2 weeks, but has never been a serious disruption in production caused by the use of Biomass furnace is out of bounds.

Yearly running hours?
Biomass is normally designed to use only the normal 5 years only, because I am difficulty finding the best materials and best refractory bricks, so we still use local raw materials. Local Materials in the Indonesia is still dominated by raw materials from China, When using the standard European and Japanese standards certainly longer durability.
Indonesia, a lot more consideration to choose the price and can not appreciate the technology. When the price is considered more inexpensive even though the raw material is not that great it will be widely used and purchased by the business community.
So we create and design of this system is based on consideration of the purchasing power of the market in Indonesia.
For the best raw materials, usually unsold in Indonesia is not being able to be bought by companies in Indonesia.

The smoke is clean enough?

Smoke on burning biomass would still be there, but it can be seen on my video data, where only a little smoke coming out, because of complete combustion. I analyze, the smoke will come out only when the biomass is burned by:
1. Temperature has not reached the point of fire
2. Less oxygen and unstable
3. The stability of the fuel temperature is not maintained
Therefore, if the 3 things mentioned above are not met then it will cause a lot of smoke.

Biomass has many types, and each has a flash point temperature, where she will begin to burn at the desired temperature. Therefore, I maintain a minimum temperature of at least 600 C Biomass Furnace, for each type of biomass can be directly burned.

On this picture, we can see, when biomass furnace operation, if the smoke produced from burning a lot, then this production room would not be apparent, so this biomass produces very little smoke from the burning of a perfect system. Can be seen more clearly in my videos.

In the combustion process must require oxygen. When oxygen is less then there will be lots of smoke, but if Excess Oxygen, then the burning will to die, because like a candle in the wind, would be dead. Therefore, oxygen is set automatically, when the temperature is too low then the low oxygen demand, when the temperature is too high then the high oxygen demand.

What do you mean with low power?

The maximum power usage only requires 6000 watts of heat input to produce a stable 2500 C (1400 C heat output).
Electric power usage is to mobilize:
1. Screw Biomass Fuel Input at Silo = 2 Hp = 1.5 Kw
2. Blower Input (To Supply Fuel) = 2 Hp = 1.5 Kw
3. Air Blower (to supply oxygen) = 2 Hp = 1.5 Kw
4. Stirring (for temperature stability) = 2 Hp = 1.5 Kw
5. Blower Output (for Charcoal and Ash Disposal) = 2 Hp = 1.5 Kw
6. Perforated blower (for the Oxygen Supply) = 1 Hp = 0.75 Kw
All Electric motor has never worked simultaneously, as adjusted according to the needs of the desired temperature,

Fuel Input will work dynamically according to the automatic setting according to heat requirements. Fuel input is electric motor that drives the biomass fuel Screw, When the temperature reached the Electric motor will move slowly and stopped dynamically, when the temperature is less then the motion of the motor Electric accelerated harmoniously until the temperature reached. So it went on during the combustion process in Biomass Furnace.

Input blower, tasked send Biomass from Silo to the Main Body Biomass furnace, its strength from 0.5 to 1 kg / second. When the temperature reached, and stop screw, then the biomass furnace temperature is higher, then served as input blower helps supply more oxygen for more complete combustion and less smoke.

Maintenance costs?

Maintenance costs, usually consisting of
1. mechanical spare parts
2. Electric motor spare parts
3. control panel components
4. Refractory bricks
5. operator maintenance
I usually count by 10% per year of Biomass Furnace prices.

Maintenance period in running hours?
Normally Biomass furnace, has Daily running hours 24 hours / day, and 6 days / week. 1 day for maintenance.
Maintenance, usually drain the contents of main body Biomass Furnace, Check condition of oil in the gearbox, Check the condition of screw-input biomass, Check the condition of sensors.
Biomass silo filling can be done when the engine Biomass Furnace is working, so no need to turn off the system.
Duties of operators are:
1. Ensure the desired temperature remains stable
2. Check the condition of the silo
3. Check the supply of fuels from biomass silo to the main body furnace

Working conditions, biomass furnaces can be automatically shut off if the sensor reading there is no boilers or other working machine that is receiving heat from biomass furnace. Biomass furnaces can also be turned off manually if at any time an interruption of work.
Biomass furnace will give an alarm when the minimum temperature (600 C) is not reached, meaning that there is interference with the supply of fuel from biomass silo

Overhaul period?

Overhaul done for reimbursement:

Refractory stone
Screw-Biomass Input
stirring
perforated

Normally Biomass furnace has a Refractory brick overhaul once every 6 months. 4 days for the replacement of Refractory bricks. Abrasion occurs, due to rubbing against the material-biomass in Cyclone spined for 24 hours and 7 days a week working. Refractory brick at temperatures over 600 C will withstand the heat and the color changed to red, and biomass will be forced to float as long as possible in the room Biomass Furnace so before falling on the pile of embers, biomass had a high temperature and so it is flammable. But in Indonesia overhaul Refractory bricks can be up to 1 year, being too busy for the operation. So the refractory bricks are designed to withstand 1 year of operations.

Normally this has a Biomass furnace overhaul Biomass Input Screw every 6 months. 1 day for replacement screw. But in Indonesia can overhaul up to 2 years, being too busy for the operation. Screw problem occur because it was not straight or also occur because of the fins of screw was separated due to rubbing against the biomass. So Screw Input is designed to hold 2 years of operation.

Stirring and perforated, work at temperatures reaching 2500 C, for 24 hours and 7 days a week. Stirring was used a special metal materials that are resistant to high temperature and radiator system is given that the condition is always chilled. Normally Biomass furnace has a 2-year overhaul stirring once. Stirring 1 day for replacement, but in Indonesia overhaul stirring up to 2 years, being too busy for the operation. Stirring and perforated so designed to withstand two years of operation.

I usually calculate Overhaul Costs by 5% per year of Biomass Furnace prices.

Product types and amount?

During the trial (2006 - 2007,) Biomass furnace aims to help the agricultural products, such as grain dryers, corn drying machine, a dryer organic fertilizer. So far, they used kerosene to dry. In the year 2006 - 2007 the price of kerosene was Rp. 2500, -/liter ($ 0.27/liter) but now the price of kerosene $ 1/liter.

So starting in 2007 - 2011, I sold the company:

Small class paddy drying capacity of 20-40 tons / day (2-4 units of machine)
Drying rice middle class 80-120 ton / day (4-6 units of machine)
Corn drying 200 tons / day (1 unit machine)
Organic Fertilizer drying 50 tons / day
Paper Sludge (450 ton / day)

For drying grain every room requires temperature 65 C, paddy dryers have 4 drying room. So that should is given total temperature is 65 C x 4 room = 260 C / machine units.

Biomass Furnace type of small (diameter 1.5 m) capable of supplying 4 units of paddy dryers. If each requires 260 C, the total heat supply to be provided by the Biomass Furnace is 260 C x 4 units = 1040 C. Stable for 24 hours of work and 7 days a week. Distance to any dryer machine reaching 18 m, whereas each 1 meter will decrease the heat 10 C. Total decrease in heat during the trip = 18 m x 10 C = 180 C. So it must be supply Biomass Furnace heat output for 1040 C + 180 C = 1220 C.

Because it is very easy operation, maintenance is also very rare, as well as all the system is set automatically (start filling biomass fuel, the temperature stability of the arrangement, until the disposal of charcoal) in Indonesia it is usually only takes 1 person operator. However, if the operator is normally two people can be better too.

Kami membuat system dimana yang penting Bukan berapa besar panas sumber yang dihasilkan Namun tungku pamanas harus dapat dipaksakan memenuhi panas yang diinginkan oleh media yang dipanaskan oleh tungku. Jadi panas yang dihasilkan lebih stabil bukan pada sumber namun pada tujuan akhir media yang dipanaskan. Oleh karena itu suplai bahan bakar diatur berdasarkan panas yang diminta oleh media yang dipanaskan. Bila kurang maka akan secara otomatis menambah suplai bahan bakar sampai terpenuhi, namun bila sudah cukup maka secara otomatis akam mengurangi suplai bahan bakar.

Inilah yang kami sebut sebagai EFFECTIVE FUEL SUPPLY
