Hot water boiler

The hot water boiler can be divided into electric hot water boiler, oil-fired hot water boiler, gas-fired hot water boiler and coal-fired hot water boiler according to different fuels. According to whether or not pressure can be divided into normal pressure hot water boiler and pressure hot water boiler, what we usually call " hot water boiler" refers to normal pressure hot water boiler. Because of its safe operation, people mostly use this kind of normal pressure hot water boiler for bathing or heating.
Tubular type
Assemble the computer boiler controller and store all the functions on an intelligent chip to realize the intellectualization, digitization, automation and humanization of the boiler. The boiler intelligently controls the water temperature to automatically stop the heating of the water temperature. The large font on the screen shows the water temperature and the furnace water temperature is clear at a glance. 2. The boiler water temperature can be set at will from 10 ℃ to 100 ℃. The boiler can supply hot water for bathing as well as boiled water for drinking. It can be used in one boiler. 3. The top of the furnace body is provided with an air vent, the boiler is in a state of no pressure and there is no danger of explosion, and the whole machine is equipped with several safety protections such as overheating protection ( when the water temperature in the furnace is too high, the heating pipe automatically stops working and beeps for alarm, secondary overheating protection ( when the temperature of the boiler shell exceeds 105 ℃, the secondary circuit is automatically cut off ), and water shortage protection against dry burning ( when the boiler water is below the extremely low water level, the boiler stops working and beeps for alarm ).

Drum type
The boiler barrel type hot water boiler, which was mostly converted from steam boiler in the early days, has a natural circulation of boiler water. In order to ensure the safety and reliability of boiler water circulation, the boiler must have a certain height. Therefore, this type of boiler has a large volume and its steel consumption and cost are relatively increased. However, due to the large water discharge capacity of this type of boiler and its ability to maintain natural circulation, boiler water can be effectively prevented from vaporizing when the circulation pump of the system suddenly stops running. It is also for this reason that natural circulation hot water boilers have developed rapidly in China.
