What is a hot oil boiler?
Hot oil boiler or thermal oil heater is a device for transferring heat between the heat receiving fluid (special thermal oil) and the heat giving fluid (hot gases resulting from burner combustion). . In these boilers, by creating the necessary heat transfer surface, the heat of the gases resulting from the combustion of the burner is transferred to the circulating thermal oil and causes its temperature to increase.
Hot oil boiler
Hot oil boilers are divided into two general categories in terms of installation and overall structure, as well as the type of fuel used: 1- Horizontal or vertical hot oil boiler: Hot oil boilers are produced horizontally or vertically depending on the capacity and design specifications, both of which have their own advantages and disadvantages. Vertical boilers are usually used in low capacities or due to space limitations. Also, horizontal boilers usually have higher efficiency. 2- Gas-burning, diesel-burning, dual-burning hot oil boilers: Hot oil boilers based on the fuel available at the installation site with a gas-burning burner or a diesel-burning burner or a dual-burning burner (gas and diesel) Or a triple burner (gas, diesel and fuel oil) is produced.
The benefits of a hot oil oil boiler
Advantages of vertical hot oil boiler The hot oil boiler of vertical design has the following important advantages: ▪️ Due to the rising properties of hot air, it has a better retention time of the heat inside the boiler. ▪️ The circulation of hot oil inside the coils is done better due to the earth's gravity. ▪️ Hot oil draining is done much faster. ▪️ It is very suitable for installation in engine houses that have less space.
Applications of hot oil boiler
▪️ Chemical industries: In this industry, hot oil boilers are used due to the need for very high temperatures. In industries such as paint manufacturing, reactors, polymerization machines, refined oils, solvent production, and glue and resin production, chemical substances are produced, the hot oil boiler can be used to generate heat. ▪️ bitumen, isogum and asphalt production industry, bitumen pool heating, lubrication and heating of heavy oil materials in large tanks ▪️ To produce controlled heating in chemical reactor and autoclave heating ▪️ Large industrial dryers ▪️ Production of chips and fries in the food industry, edible oil factories
▪️ Production of leather, engine oil, cement, etc Production of edible oils ▪️ To lubricate heavy oil materials in large tanks and also to heat them ▪️ for the production of wooden sheets, drying of wooden sheets, chipboard and MDF ▪️ Engine oil purification ▪️ Textile industry, heating of dyeing equipment ▪️ Production of candies in food industry: for the production of candies, the use of this pot has advantages such as reducing energy costs, reducing equipment costs, not needing industrial dyes, not needing powdered sugar, reducing saffron consumption, and increasing efficiency. /p>
Three methods of cleaning the hot oil boiler
1- Washing with washing fluid The method of washing with washing fluid is recommended when: ▪️ The system is not too dirty. ▪️ Fluids are chemically compatible. It is not difficult to fully drain the system. ▪️ The time should be short.
2- Washing with process system cleaner This method is recommended when the following conditions exist: ▪️ Fluids should not be compatible and be of different types. ▪️ The system should have suspended particles and light viscous carbon deposits. ▪️ The system is severely clogged with sludge or the flow is blocked in some places. ▪️ Purification of a large system, when full filling of the washing fluid is not acceptable.
3- Other factors When cleaning is done, special attention should be paid to the time and bowl of felts and liquid disposal. A common mistake is to try to do intensive cleaning on the weekend and start the setup on Saturday morning. This method is only available for small and uncomplicated systems. Considerable time at the required temperature will be required for cleaning. Always remember that proper washing is not done quickly.
