This project will adopt our ORC integrated with high speed permanent magnetic synchronous generator with Magnetically Levitated Bearing, to recover energy from 135 hot water. There is no dynamic-static seal on the unit.

The high speed synchronous alternator employ rare earth permanent magnetic rotor, its maximum efficiency can achieve 95% and more.

Magnetically Levitated Bearing use magnetic force to bear load. It is a new type bearing. There is no contact, no lubrication, no dynamic-static seal, longer service life and less maintenance cost.

The Magnetically Levitated Bearing used in this project is jointly developed by many top specialists in this field. They have a lot of experience of many years manufacturing and using magnetically levitated bearing, combination with the expertise of high speed turbine and mechanic rotors. We provide our customer with high efficiency stable reliable magnetically levitated bearing.

Its running noise level 80dB(A)

Its power consumption is only about 5%10% of conventional fluid dynamic sliding bearing

Its static and dynamic performance can be in-line controllable

The energy of hot water, by evaporator, evaporate R245fa and become vapor; The R245fa vapor works inside turbine expander to drive alternator, the generated electric current treated by rectifier and inverter, finally output about 285.2 kw electricity power.

The expected service life is designed about 20 years

The power generator module is assembled on a skid and its approximate size (L*W*H) is 3.2 m * 1.5 m * 1.6 m .

3. Heat exchanger

Organic medium heat exchanger adopt solder welding plate heat exchanger. The standard material is stainless steel. It is pure copper or nickel solder vacuum welded.

The basic material of the heat exchanger determinate the type of medium to be used in the heat exchanger. Such as synthetic oil, mineral oil, organic solvent, fresh water, Ethylene glycol mixture, refrigerant, etc.

On front panel of the solder welding plate type heat exchanger, there is a sticker or stamped arrow. It indicates the front panel and inner/external circulation position. For example, if the arrow is upward, the left side of the arrow ( connection F1, F3) is inner circulation, and the right side (F2, F4) is external circulation.

Due to one more passage, external circulation presser drop is a little lower.

Constructionthe solder welding plate type heat exchanger is composed of front and back cover plate and the corrugation passages between. The plate cover group have seal plate, gasket and cover plate.

Fluid structure: there is various flow way. Double course solder welding plate heat exchanger have two different type flow way:

typeconcurrent or countercurrent.
