ZOZEN gas-fired hot water boilers are running at full load to ensure the residential heating in the cold wave

Recently, a strong cold wave had come and many places in China had been affected. Facing the challenge of constant low temperatures, ZOZEN gas-fired hot water boilers were running at full load to guarantee the heating quality and make the residents warm in the cold wave.

Tiantuo heating center used to have three sets of 58 MW and 2 sets of 29 MW coal-fired hot water boilers and 3 sets of steam boilers with a total heating area of 3.5 million square meters. In order to promote the air pollution control, Tiantuo heating center replaced the coal-fired boilers and built a new gas-fired boiler room with 10 sets of 29 MW gas-fired boilers and auxiliary equipment in 2014. The total boiler capacity was further improved to meet the demands of increasing heating area in the future.

As a well-known brand in the northern heating boiler market, ZOZEN Boiler with advanced technology and good reputation successfully won the bidding and provided 5 sets of SZS series gas-fired hot water boilers for Tiantuo heating center. Since the project was put into use, ZOZEN gas-fired boilers had been in operation for 5 heating seasons that were 610 days or 14,640 hours. Facing the cold wave, ZOZEN gas-fired boilers were running at full load to complete the heating work for Tiantuo heating center.

The safe boiler operation is a prerequisite to ensure the heating quality. The combination of ZOZEN quality and Internet of Things provides a strong support for the work of Tiantuo heating center. ZOZEN SZS series gas-fired boiler adopts the full membrane wall structure. Its furnace is designed to bear pressure more than 6,000 Pa. The high-temperature area of the boiler adopts the forced circulation to ensure the reliable cooling of heating surfaces without vaporization, so as to keep the boiler in a good operating state and ensure the long-term operation in the heating season.

Meanwhile, the boiler is also equipped with the device to detect the leak automatically. The boiler also has other functions such as the alarms for over-temperature, over-pressure and low-pressure. With the application of Internet of Things, the boiler operator can monitor every link in the operation of the gas-fired boiler in real time, which realizes the automatic operation of the boiler. In addition to the reliability of the boiler itself, there is also the handheld gas detector in the boiler room of Tiantuo heating center and an automatic robot to inspect the boiler room and detect the gas leakage. The triple guarantee greatly enhances the security coefficient of the boiler room.

During the cold wave, meeting the residential heating demands is a major issue for people's livelihood. ZOZEN gas-fired boilers, combining the quality advantage and scientific power, will fully support the heating work at a low temperature.
