The invention provides a computer boiler safe energy-saving environmental-protection network system, consisting of a computer remote monitoring command system, a network communication system, boiler running parameter recorders distributed at all regions, and boiler control cabinets and/or boilers which are connected with the boiler running parameter recorders by data. The computer remote monitoring command system is provided with a man-machine interaction device, a user hierarchy authority management module, a boiler parameter-setting module, a boiler running safe energy-saving environmental-protection state real-time monitoring module, and a boiler running safe energy-saving environmental-protection information statistic, query, analysis and report-generation module. The system can establish the real-time communication and monitoring relationship with the safety, energy-saving and environmental-protection supervising management departments and the boiler installation and maintenance enterprises, to record, monitor and send information of safe running, energy-saving condition and environmental-protection of the boiler by Internet or GPRS and short messages of the mobile phone, thus leading relevant departments to take preventive measures in time to eliminate and avoid the running of the boiler with malfunction and to prevent the occurrence of the accidents.
