Product introduction:

Pressurized hot water boiler It refers to pressure bearing boilers. The common pressure boilers include steam boilers, heat transfer oil boilers and pressurized hot water boilers; The pressure hot water boiler is usually in the state of full water all the time. Therefore, the boiler does not have a water level gauge, but only needs to set up a pressure gauge and a safety valve. The pressurized hot water boiler can supply low-temperature hot water or output high-temperature hot water. Compared with the atmospheric pressure hot-water boiler, the function is more comprehensive and more versatile;

The boiler body of pressure hot water boiler is a closed pressure vessel. According to the different hot water outlet temperature requirements of the boiler, the pressure value of the boiler body is also designed accordingly. The common outlet water temperature of the boiler is 115 ℃ under the pressure of 10kg.

The difference between pressurized hot water boiler and atmospheric pressure hot water boiler is as follows

1. Pressure bearing hot water boiler is pressure equipment and pressure vessel, belonging to special equipment. The boiler has the possibility of explosion. On the contrary, atmospheric pressure hot water boiler does not bear pressure, and the boiler is connected with the atmosphere. Therefore, the boiler has no explosion risk at any time and has better safety.

2. Pressure gauge must be installed for pressure hot water boiler, while thermometer and water level gauge are only needed for atmospheric pressure hot water boiler, and pressure gauge is not required.

3. Different circulating water pumps. The circulating water pump used in the pressurized hot water boiler is to extract the water from the system pipe. If the water pump is uneven, it is necessary to overcome the circulating resistance of the system, and to maintain the pressure value in the boiler to maintain the hot water in the pressurized hot water boiler from vaporization at high temperature. However, the circulating water pump used in the atmospheric pressure hot water boiler is to extract the hot water from the boiler, and the ordinary hot water pump can be used.

4. Different temperature of hot water supply. The pressurized hot water boiler can supply both high temperature hot water above 100 ℃ and low temperature hot water below 100 ℃, while atmospheric pressure hot water boiler can only supply low-temperature hot water below 100 ℃.

Special precautions for selection and use of pressurized hot water boiler:

1. The pressure bearing capacity of pressure bearing hot water boiler needs to be confirmed in combination with the overall heating system. If the primary water supply for high-rise and super high-rise buildings is carried out, the static pressure of pipe network and the operation pressure of circulating pipeline should not be ignored, and the pressure demand of hot-water boiler should be comprehensively analyzed;

2. Water treatment measures should be taken before the boiler water of pressure bearing hot water boiler enters the boiler. Refer to the water standard of pressure hot water boiler to avoid the scaling and corrosion of the boiler as far as possible. The boiler needs to carry out water quality inspection and maintenance regularly to reduce the impact of water quality problems on the safety and service life of the boiler.

Advantages of pressurized hot water boiler:

1. Efficiency advantage: the pressurized hot water boiler adopts the design principle of closed pressure and multi return, with large heating area and high heat conversion efficiency.

2. Process advantages: the pressure hot water boiler is a special equipment. The boiler drawing design, production, installation and commissioning, operation and use, inspection, repair and maintenance, and boiler transformation and other links have set specified indicators. The boiler capacity, accessories, technical parameters and boiler room design are more reasonable and scientific. Therefore, the boiler of pressure bearing hot water boiler is precise It has more advantages than atmospheric pressure hot water boiler.

3. Service life and recycling: the boiler water of pressure hot water boiler is treated by water treatment equipment, so the service life of pressure hot water boiler will be longer than that of atmospheric pressure hot water boiler. After the pressure hot water boiler is stopped and eliminated, it can be transformed into atmospheric pressure hot water boiler for continuous use. The boiler has high value and can be recycled.
