Gas water boiler heating system Hot water boiler structure
1, hot water boiler tube
This type of boiler tube is more common with the two. The tube hot
water boiler is forced to flow through the head of the circulation
pump and the water pressure tank to directly heat a pot of water.
Most of these boilers are composed of smaller diameter cylinders
(heads) and pipes. They are compact, small in size, save steel,
simple in processing and low in cost. However, the boiler water
capacity is small, and in the case of a sudden power failure
operation, the water vapor may be easily generated, and a water
hammer may be generated.
2, steam drum boiler
This kind of hot water boiler, in the early days, was mostly
converted into a steam boiler, and its boiler water pot was a
natural circulation. In order to ensure a safe and reliable water
circulation boiler, there must be a certain height of boilers, so
these large boilers, steel consumption and cost are relatively
increased. However, due to the water capacity of these boilers, the
natural cycle can be maintained, and when the system circulating
water pump suddenly stops running, the steam boiler can be
effectively prevented. It is also for this reason that the rapid
development of natural circulation hot water boilers in China in
recent years.
The tube hot water boiler is forced to flow through the head of the
circulation pump and the water pressure tank to directly heat a pot
of water. This kind of hot water boiler, in the early days, was
mostly converted into a steam boiler, and its boiler water pot was
a natural circulation. The heating surface of the tail is inclined
to acid corrosion.
The gas water boiler heating system boiler includes an electric hot water boiler, a fuel hot water boiler, a gas hot water boiler, and a coal-fired hot water boiler. The hot water boiler is a boiler that produces hot water, and refers to heat energy or other heat energy (such as electric energy) released by combustion of the fuel. , solar energy, etc.) A thermal energy device that heats water to a rated temperature.
The gas water boiler heating system is divided into a normal pressure hot water boiler and a pressure hot water boiler. The atmospheric pressure hot water boiler belongs to a non-pressure civil life boiler, which is convenient, fast and safe to use, and does not need to be filed by the technical supervision department; the pressure hot water boiler is a pressure vessel. It belongs to special equipment. The design, manufacture, installation and use of pressure-bearing boilers are supervised by technical supervision departments and need to apply for boiler use certificates.
The gas water boiler heating system we usually refer to is an atmospheric hot water boiler. The atmospheric hot water boiler is not subject to conditions and there are no safety hazards. Nowadays, people choose heating, bathing and hot water for atmospheric hot water boilers.
Boiler and hot water heater requirements
The design, manufacture and inspection of the boiler shall comply
with the requirements of the "Safety Technical Supervision
Regulations for Hot Water Boilers".
The boiler should have modern technology, long-term operation
output, less air leakage, high thermal efficiency, low water
resistance, low power consumption, and low operating costs. The
boiler and its supporting equipment should be brand new, reliable,
technologically advanced and mature.
The boiler structure is reasonable and advanced, and can adapt to
load changes. It should be able to run smoothly within the load
range of 20% to 110%. The boiler has a fast heating rate, meets the
requirements of fast start-stop, fast operation, convenient
maintenance and stable performance.
Gas water boiler heating system Technical performance requirements
1, Boiler body
1.The welds of the pipes of each heating surface of the boiler
shall be subjected to 100% non-destructive inspection and shall
have the inspection certificate. Strict inspection should be
carried out before leaving the factory, and no foreign matter or
welding slag is allowed to remain in the pipe and in the header.
2.The design and manufacture of each component must comply with the
regulations issued by the state. Welding of dissimilar steels with
large differences in alloying elements in the heating surface of
the boiler should generally be completed in the manufacturing plant
and should have welding records (including pre-weld preheating,
welding methods, joint types, welding rods, post-weld heat
treatment, etc.). ).
2,Water supply tank: The boiler should be provided with automatic water supply function. And the water tank should be equipped with a water tank cover. The tank should be installed with an overflow pipe in a location with drainage. After the water tank is installed, clean up the debris in the water tank.
3,Points, water collectors
The effective length of the water separator and the water collector
shall not be less than 800 mm, and φ shall not be less than 219 mm.
4, Chimney
Diameter: D219, length: 6 meters. Low temperature discharge is
required, and the exhaust gas temperature does not exceed 200
degrees.
5,Electrical and Control
1.The bidder shall provide the boiler electrical control cabinet,
including various electrical components and electrical wiring
devices, in the factory as required by this specification. The
electric wiring device and the electric motor control and
protection equipment of the electric control cabinet shall be
provided in complete. The selection of electrical components of the
electric control cabinet should be advanced and reliable. An
alternate fuse must be provided.
2.The electronic control system should have two sets of systems;
one is for the automatic system to operate separately, and the
other is for manual system operation, any type of damage can not
affect the other normal use.
