Including hot water boiler in the boiler, hot water boiler fuel, gas hot water boiler and coal fired hot water boiler, hot water boiler is to produce hot water boiler, refers to the use of the heat energy released by the fuel combustion heat energy or other (such as electricity, solar energy, etc.) to the rated temperature of a heat to heat water equipment. "Special equipment safety supervision regulations", as defined by the boiler is the use of a variety of fuel, electricity or other energy sources, will dress up, in which heated to a certain parameter, and foreign output heat equipment. The range is defined as pressure steam boilers with volume greater than or equal to 30L; The outlet water pressure is greater than or equal to 0.1mpa (table pressure), and the rated power is greater than or equal to 0.1 Mw. Organic heat carrier boiler.

Hot water boilers can be divided into electric hot water boilers, oil-fired hot water boilers, gas-fired hot water boilers, coal-fired hot water boilers, etc. According to whether the atmospheric pressure hot water boiler and pressure hot water boiler pressure can be divided into two kinds, we usually say "hot water boiler" refers to the atmospheric pressure hot water boiler, due to its safe operation, people bathing or heating are mostly adopted the atmospheric pressure hot water boiler.

tubular

Assembly digital type main hot water boiler controller, all the functions are stored on a smart chip, implement the intelligent of the boiler, digitization, automation, humanization, intelligent control of the boiler water temperature, water temperature heating automatically stop; Large screen font displays water temperature, water temperature at a glance.

2, from the boiler water temperature 10 ℃ to 100 ℃ can be arbitrarily set, boiler can supply hot water shower, as well as provide boiled water to drink, can be a batch of dual-use.

3, furnace at the top of the atmosphere, the boiler is in a state of no pressure, no explosion danger, at the same time equipped with overheating protection (furnace temperature high, the heating tube automatically stop working and buzzer alarm, secondary overheating protection (boiler shell temperature exceeds 105 ℃, automatically cut off the secondary loop), dry lack water proof protection (furnace under low water level, water boiler stop working and buzzer alarm) such as multiple security protection.

Boiler drum

Hot water boilers such as cylindrical hot water boilers, which were converted from steam boilers in the early days, are naturally circulated in the boiler. In order to ensure the safety and reliability of boiler water circulation, the boiler must have a certain height, so this kind of boiler has a large volume, the steel consumption and the cost are relatively higher. However, since such boilers are large in water capacity and can maintain natural circulation, when the system circulation pump stops running suddenly, it can effectively prevent the pan from vaporizing. For this reason, natural circulation hot water boiler has developed rapidly in our country.

Hot water boiler is mainly used for heating and washing. The hot water boiler circulates the hot water of the circulating hot water tank through the hot water circulating pump, and then the hot water of the water tank is reheated to realize the purpose of bathing. Hot water boiler circulates hot water through hot water circulation pump, which can meet heating requirements through radiator (radiator). Hot water boiler and hot water circulating pump with heat exchanger can realize double function of bath and heating.

Structure principle

The hot water boiler of natural circulation is taken from the top of the pan, and the inlet pipe enters into the front and the lower part of the tube, which can be heated up by the water cooling wall pipe. The lower part of the bottom of the boiler tube is separated by the lower part of the wall.

For forced circulation, the access to the water front bottom allied box, water wall tube once rose last drum (water wall before the drop tube cancelled), and then into the side water wall pipe down to the bottom allied box, and rising cloth into the side water wall tube to drum, convection bundle down to water drum, and from the front end and circuitous several process between water drum, drum back-end water from. The forced circulation boiler does not have the economizer.
