Thermal Oil Heater - for High Temperature Process Heating

Heat loss from the boiler jacket could range from 1/2% to 4% of the boiler output, depending upon operating pressure or temperature, boiler size, type of construction, and insulation thickness. Typically, the larger the boiler the lower the loss as a percentage of boiler output.

Water Treatment Requirements for Low and Medium Pressure

-Operating the boiler with too high a water level.-Operating the boiler below its design pressure; this increases the volume and the velocity of the steam released from the water surface.-Excessive steam demand. 2. Foaming - This is the formation of foam in the …

Boiler/Burner Combustion Air Supply Requirements and

Due to the bed material inside the boiler, fluidized-bed boilers have high heat transfer coefficients, utilize the entire boiler volume, have a uniform temperature distribution and have a low stable combustion temperature. Fluidized beds are capable of burning very wet fuels and fuel particles of sizes up to 80 mm (van Loo and Koppejan, 2006

DIFFERENT TYPES OF HEAT EXCHANGER - mech4study

Electrical Heated. Water and steam are typically used as heat carriers in heating systems. But at high temperatures, water and steam requires a corresponding high operating pressure. In thermal oil heaters, a special oil (HTF) is used instead and it means that you can achieve operating temperatures up to 300°C at atmospheric pressure.

Thermal Design of Economizer for Waste Heat Recovery Boiler

Superheated steam is steam at a temperature higher than its vaporization point at the absolute pressure where the temperature is measured.. Superheated steam can therefore cool (lose internal energy) by some amount, resulting in a lowering of its temperature without changing state (i.e., condensing) from a gas, to a mixture of saturated vapor and liquid.If unsaturated steam (a mixture which

Jul 07, 2016 · High Pressure Boiler An industry rule of thumb is to use a low pressure steam boiler if brewery is less than 50 Bbls and a high pressure one if greater than 50 bbls. If using a high pressure boiler, many municipalities require a full time operator and your insurance rates may be much higher for a high pressure boiler versus a low pressure boiler.

improving the efficiency of a high pressure steam boiler is to install an economizer on the boiler. Typically, on a high pressure water tube boiler, the efficiency improvement with an economizer is 2 to 4%, depending on firing rate. On a high pressure fire tube boiler, the improvement is 2 to 3.5%, depending on boiler size and firing rate.

It is known fact that, the heat transfer rate from the flue gasses can be increased by increasing the velocity of gases. Thus to have high transfer rate, with reduced surface area, is by using high velocity (approximately or above sonic velocity) of flue gases. This concept is used in Vilox boiler.
