Hot air firstly goes into the heat-pipe exchanger, the heat is transferred to the inside soft water, and steam of 0.4~0.6Mpa is generated. After passing through the heat-pipe exchanger, hot air is reused to pre-heat the R/O water and generate the hot water.
Features: With the waste heat recovery system, the plant doesn’t need external steam upon cold start-up. During normal operation, plants realize steam and hot water self-sufficient.
The heat-pipe 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 shut down 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, external steam supply is no needed.
The recovery rate: 100kg sulfur burning generates 250kg steam.
The first/second stage recovery of exhaust gas generates steam; The third stage recovery produces hot water with efficiency of 36.5%, 44.2% and 67.3% respectively.
