We had already discussed the Manufacturing of Bricks in the last article, so now in this article, we are going to discuss the 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 | The initial cost is very low as no structures are to be built. | The initial cost is more as permanent structures are to be constructed. |
| Quality of bricks | Percentage of good quality bricks are small about 60% or so. | The percentage of good quality bricks is more than 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 structures are used. | Permanent structures are used. |
| Suitability | Clamp burning is suitable when bricks are to be manufactured on a small scale and when the demand for bricks is not continuous. | Kiln burning is suitable when bricks are to be manufactured on a large scale and when there is a continuous demand for bricks. |
| Time of Burning and Cooling | It requires about 2 to 6 months for the burning and cooling of bricks. | The actual time for the burning of one chamber is about 24 hours and only about 12 days are required for the cooling of bricks. |
| Wastage of heat | There is considerable wastage of heat from the 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. |
