Special energy-saving type boiler system matched with condensate water recovery system

Abstract

The invention provides a special energy-saving type boiler system matched with a condensate water recovery system. The special energy-saving type boiler system matched with the condensate water recovery system is characterized in that the special energy-saving type boiler system matched with the condensate water recovery system comprises a boiler, an energy saver and a condensate water temperaturereduction device; and boiler discharged smoke is discharged into the atmosphere after cooling by the energy saver, a low-temperature water source of the energy-saver is provided by an external low-temperature water source and condensate water with temperature reduction processed by the condensate water temperature reduction device, boiler feed water is supplied by high-temperature water heated bythe energy-saver, and cold air for boiler combustion enters a boiler furnace through heat exchange and warming of the condensate water temperature reduction device. The special energy-saving type boiler system matched with the condensate water recovery system has the technical effects that the gasification phenomenon of the energy-saver is avoided, the temperature of the boiler discharged smoke is reduced, the heat efficiency of the boiler system is improved, the cold air for the boiler combustion is directly used for the condensate water temperature reduction device and the condensate waterfor heat exchange, the temperature of the condensate water is reduced, and generated hot wind is more beneficial to the combustion of the boiler.

Description

technical field [0001] The invention relates to an energy-saving boiler system, in particular to a special energy-saving boiler system matched with a condensed water recovery system. Background technique [0002] With the rapid development of economy, people's awareness of energy saving and environmental protection is also increasing. In recent years, more and more enterprises have carried out condensate recovery work. From open system recovery to closed system recovery, the efficiency of condensate recovery and utilization is also getting higher and higher. [0003] However, as the vast majority of users adopt closed systems (or open systems) to recover condensed water and use it directly in boiler systems, some problems have also been exposed. [0004] One is the gasification of the economizer, which affects the stable operation of the boiler system; [0005] The second is that the exhaust gas temperature of the boiler is too high, and most users generally reach about 15...

Problems solved by technology

[0003] However, as the vast majority of users adopt closed systems (or open systems) to recover condensed water and use it directly in the boiler system, some problems have also been exposed

[0004] One is the gasification of the economizer, which affects the stable operation of the boiler system;

[0005] The second is that the exhaust gas temperature of the boiler is too high, and most users generally reach about 150°C

In this case, if the working pressure of the user's boiler is around 0.7MPa, gasification of the economizer will also occur
