With the development of social economy and the continuous improvement of people's lives, more and more of the requirement of environmental quality. Long term since, Haoyuan group has always adhered to the "environmental protection is the enterprise lifeline" purposes, continue to increase investment in environmental protection, vigorously carry out environmental remediation work, really fulfilling environmental responsibility and obligation.

At present, along with the 1# boiler denitration project installation is complete, the boiler flue gas denitration Haoyuan company (SCR) project has been completed. The project by the environmental protection department is responsible for the safety, overall, matched by boiler workshop, instrument workshop, machine company, which lasted nearly two months time. Because this project is the transformation of the old units with new technology, so the beginning of the implementation has certain difficulty, but the task, we refer to the design drawings of mutual learning and research, one by one to solve various problems encountered in the construction. The project first began the transformation from 4# boiler, furnace body is very difficult because of high transportation for installation of pipe fittings, valves, meters and other materials, and the DCS operating system in flue gas desulfurization post, wiring distance is far, the construction difficulty. But Hao source person develop not afraid of hardship, dare to win the battle of the spirit, through the joint efforts of all the installation personnel, time after nearly a week more successfully completed the transformation of 4# boiler. Then the 5# boiler, 6# boiler and 7# boiler and 3# boiler and 1# boiler complete transformation.

The completion of the project after the transformation, after a period of trial operation, analysis and comparison of test data acquisition, significantly reduce emissions of nitrogen oxygen compounds content in boiler flue gas, has reached the national emission standards for environmental protection. Flue gas denitrification (SCR) the successful renovation project, marking the environmental protection work of Haoyuan company into a new stage.
