What's the difference between boiler heating and heat exchange station heating?

First of all, the roles are different.

1, boiler room heating; Generally speaking, it means that the hot water generated from the boiler is directly supplied to the heat users. This is low-temperature hot water. The temperature control valve with a design temperature of 95-70 degrees is used for radiator heating, while the temperature control valve with a design temperature of 55-45 degrees is mostly used for floor heating.

In addition, boiler combustion needs to consume energy, such as coal, oil, natural gas or other fuels, and consumes a lot of electricity. At the same time, corresponding operation and management personnel are needed. Furthermore, how to buy a boiler? The investment in auxiliary equipment is not small. Just don't have to pay the heating fee to the heating enterprise every year.

2, heat exchange station heating; ? Self-operated temperature control valve uses primary heat energy (steam or high temperature heat) provided by urban heat source. Water) indirectly exchanges heat into low-temperature hot water that users actually need through a heat exchanger, and then uses it? After the secondary circulating water pump of household system is pressurized, it is directly sent to all kinds of heat users through secondary pipelines.

Heat energy is provided by urban heat source, and users only need to pay the heating enterprise every year. Heating bill. Save a lot of construction and operation management costs, only need a small replacement? The hot station can solve the problem. ?

Second, the investment cost is different.

1, invest in the boiler room; The upfront investment and operation management costs are relatively high. What is the contrast between maintenance and management? Trouble. It also involves environmental protection, project approval and other procedures. ?

2. Investment in heat exchange stations; Small initial investment, simple equipment, easy maintenance and overhaul, project? The implementation is safe and environmentally friendly. Steam from power plants can also be used. Is this in line with the national energy-saving policy? In terms of policy, the heating effect is quite stable and guaranteed. Only the steam pipeline leading to the heat exchange station needs to be built, and the condensed water can be directly used for secondary water supply without recovery. ?

Third, the system links are different.

1, the boiler room uses fuel to heat water (or other media) to a place with certain parameters; The purpose of the heat exchange station is to convert the high-temperature hot water generated in the boiler room (higher than 100C) into hot water that can directly supply heat to users (lower than 100C).

2. Boiler room is a production place, and its main equipment includes: boiler, blower, induced draft fan, circulating pump and various auxiliary equipment (coal feeder, slag remover), in which boiler is the main part. The heat exchange station is a transfer station. At present, the main heat exchange methods of the heat exchange station are: heat exchange plate, mixed water and so on.
