Fix Grate Coal Combustion

This coal combustion system is the most simple of all the coal combustion system. This unit used many to modify Boiler oil fuel to change over to coal fuel. This unit earn application for all type of boiler which oil fuel like Diesel fuel ( IDO), Kerosene, gas, and other petroleum fuel 

 Also can be used for boiler which have small capacities such as used by in many home industry and other small industrys. See the level of yielded cost-saving hence if your industry incapable of have invesment to buy new unit of coal boiler hence this alternative become very precise choice to conduct energy cost clipping and thrift very high energy cost.

Combustion process of coal happened at burning room airtight, this matter is meant so that yielded heat is castaway is not free. Coal put down above combustion grate which compiled in such a manner coal so coal not fall downwards.

Combustion primary air blown from direction under passing in between coal, requirement of combustion air adapted by the amount of burned coal.

Some application for this combustion system are following bellow:

• Steam Coal Boiler

 

Fix Grate Combustion aplly on 4 ton per hour Steam Boiler

Application at steam coal boiler very precise, considering this combustion system including most of simple among existing combustion system. Jjust only for boiler which have big capacities above 10 tons per hour, combustion system with this fix grate combustion less compatible because of requirement of coal campare with very big stove burden frequently result combustion process annoyed often the happening of cloting coal which burnt.

• Heat Exchanger

This heat exchanger used to dry coconut shell of coconut briquette which is just mold to become form of bricket so that turn into realy dry so it's easy to burn.

Pulverized Coal Burner

Pulverized coal burner on prinsipel coal grinded until it's like powder than spray to chamber. Pulverize Coal Burner ( PCB) in the early its growth application for the system of combustion which have big capacities like Boiler power plant. This time, CV. PANCA WAHANA ENGINEERING have succeeded developing it as unit which multi function and earn application at middle and small scale combustion sytem. See excellence of this PCB we develop can be exploited by wide society especially Industrial world which in this time experiencing of many problems in fuel cost. It's can be your energy solution by using this Pulverized coal burner.

The main parts of Pulverized Coal Burner are listing below:

• Feeding Conveyor

This unit function as coal supply to coal crusher . Coal input into bin then carried over into  coal crusher. This unit only operated if coal tandon in coal silo have attenuated.

• Coal Crusher

If size used coal more than 15 mm hence coal will be crushed by this unit. And it size less than 15 mm so this unit can be unused.

• Bucket Coal Lifter

Coal which have been crushed of the size less than 15 mm will be transported by Bucket Coal Lifter to Coal Silo. Easy system operation and treatment which is not complicated make this unit rely on to be used at PCB.

• Coal Silo

After  crushing process by unit of coal crusher which have is fairish less than 15 mm, coal will accomodated in coal silo . Relocation capacities depended on how big the needed capacities, so that operation of unit PCB not annoyed by coal supply.

• Screw Feeder

Requirement of needed coal in course of combustion will be arranged by this unit. Coal which accomodated in coal silo will be distributed by this Screw Feeder to unit of Pulverizer (coal grinder)

• Pulverizer (Grinder)
  

From coal feeder screw which size less than 15 mm will be attenuated again size so that 0 up to 0.08 mm. This matter meant so that coal become flammable.

• Combustion Chamber
  

This unit represent place the happening of combustion of coal. Coal which have refined spray into chamber so that happened combustion process which later yielded heat distributed to application unit.

• Force Draft Fan

Requirement of air combustion in combustion chamber from Force Draft Fan. So that happened perfect combustion in combustion chamber,  temperature in combustion chamber taken care on mare than 600 deg C. From other side that requirement of combustion air also can be adjusted from attached dumper at side of inlet Force Draft Fan.

We can see these process on schematic flow chart below:

This Pulverized coal burner can be apply on:

1. Coal steam boiler
2. Asphalt mixing plant
3. Dyer
4. Thermal oil boiler
5. Heat exchanger
6. Hot water boiler
7. Dyer for coconut shell bricket

Pulverized applied on "Asphalt Mixing Plant"

Pulverized applied on "Steam Coal Boiler"

Saving Energy

The price of fuel oil rise up unrestrained in a few decade end, especially for industrial used. This make some industry become collapse caused by uncovered energy cost. Look formula below to check how big difference the cost for energy at the same callori used.

This formula get from the constancy energy that input energy are same as output energy (of couse after reduce by equipment efficiency)

After we submit the value we can get the summary like listed bellow

With this high saving cost of steam energy used Coal become famous alterntive energy source. Let we see how big cost saving if we compare between diesel oil and coal.

Exampel.1

Company A use diesel oil for product 10 ton steam/hour. They spent 806 ltrs/hour diesel oil, if price diesel oil at Rp. 6,100.-/ltr so they spend money Rp. 4,916,600.- /hour to produce 10 ton steam/hour.

Company B use coal for produce 10 ton steam/hour. They spent 1,047 kg/hour coal, if the price of coal Rp. 800.-/kg so they spend money Rp. 837,600.-/hour to produce 10 ton steam/hour.

In above case company A and company B same used 10 ton steam/hour, but they spent so big difference in money.
