บท 138: Combustion chamber
The inside of this empty cylindrical space would be accomodating the burning coal and it was perforated to ensure that the heat from the coal spread evenly to the bricks that lay on it curvature.
Of course, bricks would be arranged inside the regenerator. These bricks would surround the cylindrical bore of the regenerator.
Moreover, two pipes would pass through the arranged bricks inside the regenerator and one of these pipes would be carrying fresh air to the furnace while the other would be a flue pipe.
Coming to the furnace(melt tank) itself, the entirety of the furnace would be made of refractory bricks. This furnace would be shaped like a cuboid with a curved roof which made it to look like a house but two opposite fases of its walls would have many perforations that connected to twin combustion chambers through the ports.
The base of the combustion chambers and that of the furnace would not be allowed to touch the ground and they would be suspended in the air by piers for support.
The combustion chambers would allow their hot flames into the furnace through the ports. As the production of the hot flame from coal would only be possible because instead of using the foot bellows to pump hot air into the combustion chambers, Virtya would use large pistons which would run in large cylinders connected perfectly to the perforations of the combustion chambers.
Of course, a crankshaft that would be run by the transmitted rotary motion of the turbine, would be the one to ensure the forward and backward motion of the pistons.
With no valve or a meaningless hole around the combustion chambers, it would be the hot air from the burning coal that would push the pistons outwards while the camshafts would not only push the pistons inside, but they will also help the hot air in pulling the pistons outwards. Nonetheless, when the pistons are pushed inside the cylinders, they would pump the hot air into the hot coal which would make it to burn hotter to create the hottest flame which would be forced through the ports that connected the combustion chambers and the furnace so that the flame burned the raw materials to make glass. The flame would only pass through the ports because of the pushing force of the pistons.
Furthermore, the furnace would have two pipes that would bring in preheated air from the regenerator and the other one would bring in preheated raw materials from the batch preheater.
And since there was no electricity to pass electric currents through the molten glass to ensure that it melted perfectly, Virtya decided to construct another combustion chambers on the roof of the furnace that would ensure that the temperature of the furnace grew hotter and hotter.
On the 1st of October, Virtya visited the site and at this point, the factory was sixty percent completed.
The regenerator was already completed and it was only the furnace and the combustion chambers that were still being built.
However, on this day, Virtya was not going to hang around here the whole day because this was the day that the cement plant was going to be opened..
Virtya had to go back to his lodge and prepare for this day.
"What do you think about the developments in Azuhai as compared to Litkesh kingdom?" A boy beside Nadya asked her.
It was very early in the morning and Nadya and her caravan woke up early to start their journey to Pollow and it was at this time that they had finally arrived in Pollow.
"It is complicated. It is as if Litkesh kingdom is far much ahead of Azuhai but when one comes to Whiddiff city, they would meet many new things that remain a fantasy in Litkesh kingdom. Well, you need to know that even if Litkesh kingdom has monopolized the market of the ox drawn plough and the farm tools, it couldn't be denied that it was here in the kingdom of Azuhai where those heavenly tools came from... Yes, it was king Virtya himself who invented the almighty ox drawn plough..."
"Wait... Wait! I don't understand. I thought it was you who invented the Ox drawn plough." The boy was so confused and surprised at this fact.
Nadya sighed and continued,
