We had already discussed about the Manufacturing of Bricks in the last articles, so now in this articles we are going to discuss about difference between clamp burning and kiln burning.
Comparison between Clamp Burning and Kiln Burning
| Factors | Clamp Burning | Kiln Burning |
| Capacity | It is possible to prepare approx. 20000 to 100000 bricks at a time. | Average 25000 bricks can be prepared per day. |
| Cost of fuel | Cost is Low as grass, cow dung, litter, etc. may be used. | Cost is high as coal dust is to be used. |
| Initial cost | Initial cost is very low as no structures are to be built. | Initial cost is more as permanent structures are to be constructed. |
| Quality of bricks | Percentage of good quality bricks is small about 60% or so. | Percentage of good quality bricks is more about 90% or so. |
| Regulation of fire | It is not possible to control or regulate fire during the process of burning. | Fire is under control throughout the process of burning. |
| Skilled Supervision | Not necessary throughout the process of burning. | Continuous skilled supervision is necessary. |
| Structure | Temporary structure are used. | Permanent structure are used. |
| Suitability | Clamp burning is suitable when bricks are to be manufactured on a small scale and when the demand of bricks is not continuous. | Kiln burning is suitable when bricks are to be manufactured on a large scale and when there is continuous demand of bricks. |
| Time of Burning and Cooling | It requires about 2 to 6 months for burning and cooling of bricks. | Actual time for burning of one chamber is about 24 hours and only about 12 days are required for cooling of bricks. |
| Wastage of heat | There is considerable wastage of heat from top and sides and hot flue gas is not properly utilized. | Hot flue gas is used to dry and preheat raw bricks. Hence wastage of heat is the least. |
