The heat-pipe heat exchanger has high heat transmission efficiency. The equipment also has a compact structure and small thermal side flow resistance. Its structure is safe, reliable, and better than the heat exchanger of other structures, and the damage of a single (or few) heat pipe will neither affect the overall performance of the equipment nor affect the plant production.
The waterway is outside the flue, so it requires no shutdown for replacement and overhaul.
Design life is 10 years plus. This equipment is used in combination with the start-up pre-heater, which produces steam before cold start-up, an external steam supply is not needed.
The recovery rate: 100kg sulfur burning generates 250kg steam.
The first/second stage recovery of exhaust gas generates steam;
The third stage of recovery produces hot water with an efficiency of 36.5%, 44.2%, and 67.3% respectively.

Detailed Technical Advantages of WEIXIAN Heat-pipe Heat Exchanger :
Unit 68 Waste Heat Recovery adopts Three-stage-recovery Technology and Heat-pipe Heat Exchanger for realizing plant steam and hot water self-sufficiency. Compared with Fin-type Heat Exchanger (3-5 years life), Heat-pipe type featured in longer serving life, also when designing we reserve 20% extra Heat Pipes for spare, so the system can last for 15 years. Moreover, with the Start-up Preheater, this system can produce steam by itself for sulfur melting before the sulphonation plant start-up, therefore the external steam supply is not needed before and during the planting running.
Since 21st century, WEIXIAN is leading the innovation and progress of sulphonation/sulphation technology. WEIXIAN is the pioneer who introduced these technologies into the industry, such as Unit 79, Unit 69, Unit 38, Exhaust Gas Circulation Process, etc. Moreover, WEIXIAN keeps improving and perfecting the details of each key piece of equipment, such as converters, scrubbers, heat exchangers, pumps, blowers, mixers, etc. Focus comes from the love of what we are doing, as a sulphonation/sulphation technology specialized engineering company, we are confident about our technology leadership in the world market, and we are aiming to serve investors not only from Asia but also from all over the world. Choosing WEIXIAN is your most efficient solution for investing in state-of-the-art sulphonation plants.
