I. Equipment purchase details:

2 gas pressure hot water boilers (including body, burner, instrument valve, electrical control cabinet, flue, chimney and boiler, etc.).

Gas boiler parameters and technical requirements:

1. Boiler thermal power: 2.8MW

2. Boiler design pressure is 0.7MPa

3. Boiler supply and return water temperature (℃): 95/70

4. Boiler thermal efficiency ≥ 90%

5. Gas consumption ≤155m/h

6. Boiler flue gas emission complies with current national indicators and environmental protection requirements (i.e. 1. Nitrogen oxide ≤ 200mg/m³, 2. Sulfur dioxide ≤ 50mg/m³, 3. Smoke concentration ≤ 10mg/m3)

7. The boiler has an automatic control system: it has safety control functions such as automatic ignition, automatic purge before ignition, flame detection, flameout protection, wind pressure protection, gas high and low pressure protection, and gas valve leak detection; Protection, using PLC intelligent control.

8. The warranty period for boiler equipment and installation is two years (two heating seasons).

II. What is the gas consumption of a 2.8MW gas-fired hot water boiler?

It is very important to calculate the gas consumption of the boiler, which is related to the fuel cost of the boiler and is of great help to the calculation of the operating cost of the boiler. The gas consumption of Zhengzhou Boiler's 2.8MW gas-fired hot water boiler can also be said to be the gas consumption of a 4-ton gas-fired boiler, which is about 300Nm3 per hour, and a 1-ton boiler consumes an average of 75Nm3 per hour.

3. Two 2.8MW gas-fired hot water boilers for heating of the Chinese Academy of Social Sciences

The Chinese Academy of Social Sciences is the highest academic institution and comprehensive research center for Chinese philosophy and social science research directly under the Central Committee of the Communist Party of China and directly under the State Council. In the "2014 Global Think Tank Report" released by the University of Pennsylvania, the Chinese Academy of Social Sciences ranked 20th "Top 50 Global Think Tanks" and "Top 50 Think Tanks in Asia".

The customer purchased a total of 2 Zhengzhou Boiler boilers, the boiler model is WNS2.8-1.0/115/70-Q (2.8MW or 4 tons of gas-fired hot water heating boiler).
