Dependable Performance 700kw gas fired hot water heater Instant Induction Hot Water Boiler Heaters


Gas fired hot water heater features


The working atmospheric hot water boiler heating system relies on the flow resistance and pressure values. The use of hot water boilers for heating energy-saving effect is more obvious, the boiler is not allowed to have any part of vaporization, the boiler water capacity is small, in the case of sudden power failure operation, water vapor is easy to cook, water hammer may be generated.


1, boiler working pressure
The working atmospheric hot water boiler heating system relies on the flow resistance and pressure values. The working pressure of the hot water boiler, the nameplate only gives the force to make the pressure of the boiler, but in actual operation, the boiler pressure tends to be lower than this value. Therefore, the safety margin of hot water boilers is relatively large.

2, with smoke and a pot of water, small scale large temperature difference, so that good heat transfer efficiency is higher.

3. The energy-saving effect of using hot water boilers for heating is more obvious. There is no hot water heating boiler steam heating steam loss, the loss is also greatly reduced, the sewage treatment system and traps have greatly reduced leakage, and heat loss is also reduced. Therefore, it can save 20% of fuel compared to steam hot water heating system heating system.


4. The boiler is not allowed to have any part of vaporization, otherwise it will destroy the circulation of water.


5, no oxygen water, oxygen corrosion is prominent; tail heating surface temperature acid corrosion tendency.


6. From the operation of the precipitating water dissolved gas boiler, structural problems need to consider the elimination of gas.


The Gas fired hot water heater 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 fired hot water heater 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.
