The furnace and steam drum of a boiler
Much the same as pumps, blowers and other factory hardware that is made out of different parts with the goal that the gadget can work and do its part. The calderas pitotubulares are likewise made out of different segments with their particular capacities.
The following is the capacity of 2 of the 9 parts in the boiler, in particular:
This section is the place where the combustion of the fuel will be the source of heat, the process of receiving heat by the water medium is carried out through a pipe that has been drained by water, the pipe is attached to the wall of the furnace. The process of heat transfer in the furnace occurs in three ways:
Radiation heat transfer, where there will be heat emission from fire or gas that will stick to the tube wall so that the heat will be absorbed by the fluid flowing in it.
Heat transfer by conduction, heat flows through the conductor from the side of the pipe which receives heat into the side of the pipe which gives heat to the water.
Heat transfer by convection. the heat that occurs with the contact of water molecules so that heat will spread to each stream of water.
Inside the furnace, the combustion chamber is divided into two parts, the first and the second. In the first room, inside it will be heating directly from the heat source received by the tube (pipe), while in the second room located at the top, the heat received comes from the hot air from the combustion from the first room.
Steam drum serves as a place to store hot water as well as the place where steam is formed. This drum holds saturated steam (saturated steam) and water in a ratio between 50% water and 50% steam. to avoid the water not being carried away by steam, it is fitted with bulkheads, water that has a low temperature will drop down and high-temperature water will rise up and then evaporate.
