Both four-in-one and three-in-one hydrochloric acid synthesis furnaces are applied for hydrochloric acid production, integrating the synthesis section, cooling section, absorption section and tail gas absorption tower into a single unit.

Compared with the three-in-one synthesis furnace, the four-in-one model features a smaller footprint, generally suitable for working conditions with a hydrochloric acid capacity below 250 metric tons per day (MTPD).

Meanwhile, we can fully recover the heat generated from synthesis reactions to produce hot water or steam according to your customized requirements.

Equipped with an automatic control system including an auto-ignition unit, the system can realize fully unattended on-site operation.
