Harbin Thermal Power Co., the main city of Harbin is the largest cogeneration business, the company bear the city's heating area of 24 million square meters, to provide heat supply for more than 400 agencies, enterprises and 140,000 residents. Currently, the company is actively respond to the latest environmental standards introduced in China, the group mobilized up and down, stepping up technological innovation, upgrading environmental protection facilities, the project is expected to complete upgrading coal-fired boiler at the end of this year.
Harbin Thermal Power Co., the existing five boilers for heating and power generation: where to cogeneration units No. 7,8,9, and the other two hot water boilers. No. 9350 MW units which since 2017 was completed and put into operation, has achieved ultra-low emissions standards during construction. 7, No. 8 is 300 MW units were built in 2005 and 2006, these two units of environmental transformation began in 2013. Harbin Thermal Power Co., according to the latest environmental requirements, environmental upgrading facilities. First, soot emissions transformation, the introduction of advanced electric bag filter, followed by addition of sulfur, in addition to the transformation of nitrate, new burners in addition to the low nitrogen oxides of nitrogen, a wet desulfurization technologies in addition to sulfur dioxide. After four consecutive years of continuous transformation, 7,8 units in 2017, all the transformation is completed, achieve ultra-low emissions standards. For the two 116 MW hot water boiler was built in 2013, it has long been included in the transformation plan. Earlier this year preparatory work has been completed and environmental transformation has entered the bidding process in mid-October to start construction, completed renovation project at the end of December.
Boiler heat load automatic real-time tracking, the number of power control of the boiler, to optimize the combination device, to achieve high efficiency. Power Saving by the primary circulation pump return water temperature constant level software, temperature, pressure control, to achieve high efficiency. Power Saving by the secondary circulation pump return water temperature constant level software, temperature, pressure control, to achieve high efficiency. Reduce daily operating costs of the system.
The role of gas-fired boiler economizer, type and price: the boiler is a large energy-consuming equipment, gas boiler economizer is based on this born. To save energy, a high temperature flue gas discharged from the waste heat boiler reused, manufacturers will economizer mounted near the top or rear of the boiler flue, feedwater heating member. Mounted gas boiler economizer by lowering the flue gas temperature, can improve the efficiency of the boiler, so as to achieve the purpose of saving fuel.
(5) to develop regular inspection system. When the boiler is running, on-site personnel must confirm the status of the boiler, which requires the operator to do the inspections on time, within the stipulated hours, the entry point for a basic check of the boiler one by one to confirm and make the relevant registration record to facilitate subsequent queries, if there is an exception, to promptly inform superiors, together with the timely processing of abnormal, early prevention of accidents.
