gas boiler heat exchangers consist of stainless steel plate packs, which have embossed chevron patterns. The plates are turned 180 degrees to each other, causing the plate ridges to intersect and creating a lattice of intersecting channels. Fluids can flow in counter-current and co-current way. The entire construction is nondismountable and scaled together by means of brazing in a special vacuum furnace.

Major advantage over a conventional gas boiler heat exchangers in that the fluids are exposed to a much larger surface area because the fluids spread out over the plates. This facilitates the transfer of heat, and greatly increases the speed of the temperature change. gas boiler heat exchangers are now common and very small brazed versions are used in the hot-water sections of millions of combination boilers. The high heat transfer efficiency for such a small physical size has increased the domestic hot water (DHW) flowrate of combination boilers. The small gas boiler heat exchangers has made a great impact in domestic heating and hot-water

Corrosion protection for gas boiler heat exchangers, stainless steel has a high resistance to most chemicals but is sensitive to chloride ion concentration so this must be limited to 280ppm or less(lower than 55 C),the copper used in the brazing process is mainly sensitive to strong acid and ammonia so the PH must be maintained between 6 to 8.in practical application.for example,hydrochloric acid should never be used to clean the gas boiler heat exchangers;if gas boiler heat exchangers are applied in seimming pool heating,limite chloride ion concentration to 280ppm in the water;what's more,in chemical,pharmacy and other industries,solutions containing strong acid like hydrochloric acid and harshorn won't be proper fluid medium.

Applications for the brazed plate heat exchangers:

This is an extremely popular unit for wood burning furnaces, radiant floor systems, refrigerant systems, straight vegetable oil conversions, beer chilling, air conditioning system and solar water heating systems. It will work for any application in which the desired result is for two fluids (liquid or gas) to exchange heat.
