1 The use of condensate recovery technology energy saving
Boiler steam generated by the production of heat equipment after the generation of condensate, in the use of industrial boilers, more than 95% of users did not condensate recovery, most of which is when the wastewater discharged, in fact, the temperature of this part of the condensate can be as high as 60-100 ℃ and the water quality is good, the recycling of residual heat can reduce fuel consumption, energy savings of up to 10-15%, and the use of energy-saving measures.
2 Thermal insulation and energy saving Many of the industrial boiler body, steam pipes and heat-consuming equipment exposed air or only take simple insulation, a large amount of heat energy in the transmission process. If the boiler body, steam pipes and heat-consuming equipment to implement thermal insulation, heat preservation and energy saving effect is obvious.
3 Control system energy-saving transformation
Industrial boiler control system energy-saving transformation of two types, one is the coal-fired boiler's main auxiliary blower and induced draft fan operating parameters and boiler thermal efficiency and energy consumption is directly related to the appropriate speed control technology, according to the boiler's load needs to adjust the blower, induced draft to maintain the boiler running in the condition, on the one hand, you can save the boiler coal-fired, but also save the fan's power consumption, the energy-saving effect is very good. Second, the original manual control or semi-automatic control into fully automatic control. This type of transformation, for the negative
This type of transformation, for the load changes, and frequent changes in the boiler energy-saving effect is very good, generally up to about 10%.
4 The arch of the furnace transformation in accordance with the actual use of coal, appropriate changes in the shape and location of the arch of the furnace, you can improve combustion conditions, improve combustion efficiency, reduce coal consumption, and now there are applicable to a variety of coal types of the arch of the furnace configuration technology. This transformation can be about 10% of the energy-saving effect, the technical transformation investment can be recovered in about half a year.
5 Boiler retrofitting coal (oil, gas) energy saving measures to reduce consumption
Flue installed on the coal economizer, air preheater and other coal-saving devices, the exhaust temperature can be reduced to below 150, greatly improving the thermal efficiency, reduce coal consumption.
6 Change the boiler drum, induced draft fan regulation to achieve energy saving and consumption reduction .The use of frequency conversion speed control technology, you can change the frequency of the power supply through the frequency converter speed controller, and then adjust the speed of the blower, induced draft fan, to adjust the purpose of the air volume. Because the boiler in the entire heating period 95 ~ 98% of the time because of the non-full-load operation, so the use of this technology, the boiler drum, induced draft fan power savings of 35% ~ 40%. Emphasis on heating boiler energy saving can reduce energy waste.
