It is a fact that to date there are still many ships that use steam power installations, whether it is a parent installation or for the use of auxiliary aircraft. In steam tankers, the result of the Calderas is usually used as a heater, either heating fuel, heating, water heater, cargo heater or for other purposes so that ship operations can run smoothly.
The boiler or may also be referred to as the steam boiler is a closed vessel which can form a vapor with greater pressure from the atmosphere essence by heating the boiler water inside with the hot gases from the burning of the fuel. A boiler or boiler must be equipped with equipment to help its performance so that the boiler operation runs safely. Boilers or boilers must have the following requirements:
It can produce steam of a certain weight at a certain time, and the pressure is greater than one atmosphere.
The water content produced in hot steam must be slightly upset.
When using the steam heater, the steam temperature in the last steam use does not change too much.
Steam should be in the form of the number of fuel as possible.
If steam usage varies, the vapor pressure should not change much.
TYPE OF BOILER AND APPEDANSINYA / equipment
On motorboats, the use of steam is of course only in use on aircraft aids only. While on steamers, the main use of steam is to move the master machine, while other uses are for the purpose of the auxiliary aircraft. Therefore boilers or boilers can be distinguished according to the substances that flow into the pipes, namely:
a. Kettle Pipe Fire
It is a kettle where the combustion gases flow inside the pipes while outside the water flows the kettle.
b. Water Pipe Boiler
It is a boiler in which boiler water flows in the pipes while outside there are combustion gases.
