The correct water circulation of the gas hot water boiler can effectively prevent the water vaporization and water hammer and other bad phenomena from occurring after the water circulation pump suddenly stops. Based on years of industry experience, FANGKUAI Boiler will summarize the protection measures for the water circulation of gas hot water boilers for your reference.
1. Between the inlet and outlet pipes of the circulating water pump, set the bypass pipe of the check valve, the pipe diameter should be close to the mother pipe, and the cross-sectional area of the bypass pipe should not be less than 1/2 of the cross-sectional area of the parent pipe; check valve The direction of the water flow should be consistent with the direction of the water flow of the pump.
2. A heavy hammer type micro-opening safety valve is arranged on the inlet pipe section of the circulating water pump, and the overpressure drain pipe can be connected to the open water supply tank or the drainage ditch.
3. Each boiler outlet pipe shall be equipped with a shut-off valve or gate valve. The boiler inlet and supply pipes shall be provided with a shut-off valve and a check valve.
4. When the hot water boilers are operated in parallel, a regulating valve shall be installed on the inlet pipe of each boiler so that the deviation of the outlet water temperature of the parallel boiler does not exceed 10 °C.
5. The gas collecting and exhausting devices shall be installed at the high point of the boiler outlet pipe and the gas gathering place. The size of the exhaust valve shall not be less than DN20.
6. The lower part of the system and the low recess should be provided with a drain pipe and a drain valve.
7. The decontamination device should be installed at the position where the hot water system return water main pipe is convenient for cleaning. There should be a pressure gauge and a closing valve before and after the decontamination device, and there are bypass pipes 1 to 2 smaller than the main pipe.
8. There should be multiple water heaters and water collectors in the boiler room for hotspots. The water separators and water collectors should be equipped with drain valves, thermometers, pressure gauges, etc.
FANGKUAI Boiler has successfully concluded its participation in the China Import and Export Fair (Canton Fair), marking another valuable opportunity to connect with international customers and explore new business opportunities in the industrial boiler market.
The exhibition brought together buyers, distributors, and industry representatives from different regions. Through direct communication and product discussions, FANGKUAI Boiler introduced its industrial heating solutions and gained further insight into the requirements of customers seeking efficient and dependable boiler equipment.
During the exhibition, FANGKUAI Boiler focused on industrial boiler applications and solutions designed for different production processes. Our team discussed boiler selection, fuel options, operating requirements, and equipment configurations with visitors interested in improving their industrial steam and heating systems.
Our product portfolio covers a variety of industrial boiler solutions, including:
Gas-Fired Boilers: Designed for industrial applications requiring reliable steam or hot water using natural gas and other suitable gaseous fuels.
Oil-Fired Boilers: Available for factories and industrial facilities that use diesel or other applicable liquid fuels.
Steam Boilers: Suitable for manufacturing processes in industries such as food processing, textiles, chemicals, and pharmaceuticals.
Hot Water Boilers: Designed for industrial heating and process hot water applications.
Energy-Efficient Boiler Systems: Configurations that can incorporate heat recovery and other efficiency-enhancing technologies, depending on project requirements.
Customized Boiler Solutions: Equipment configurations developed according to required capacity, working pressure, fuel supply, installation conditions, and local regulations.
These discussions highlighted the importance of matching boiler specifications to actual operating conditions rather than selecting equipment based solely on rated capacity or initial purchase price.
Direct communication remains an important part of understanding industrial customers' needs. At the Canton Fair, FANGKUAI Boiler had opportunities to discuss a range of project considerations with visitors, including production demand, energy consumption, operating costs, equipment installation, and environmental compliance.
For customers planning to purchase an industrial boiler, several factors deserve careful evaluation:
Required steam output or hot water capacity
Available fuel types and local fuel prices
Operating pressure and temperature requirements
Energy efficiency and long-term operating costs
Emission requirements and applicable safety standards
Installation space, maintenance access, and after-sales support
By understanding these factors at the early stage of a project, customers can make more informed equipment decisions and identify solutions that better suit their production needs.
FANGKUAI Boiler looks forward to continuing these discussions and providing technical information to customers evaluating new boiler installations or upgrades to existing systems.
Industrial facilities have different heating demands, production schedules, and energy resources. A suitable boiler solution should therefore consider the entire application, from fuel selection and system configuration to operating performance and maintenance requirements.
FANGKUAI Boiler provides industrial boiler solutions for a range of industrial applications, with equipment options designed to address different steam and hot water demands. Depending on the project, customers can discuss capacity selection, fuel compatibility, auxiliary equipment, control systems, and heat recovery options with our team.
Our goal is to help customers evaluate practical boiler configurations that align with their operational requirements and project budgets.
The successful conclusion of the Canton Fair marks the end of the exhibition, but it also provides a starting point for further communication and potential cooperation.
FANGKUAI Boiler appreciates the interest and time of everyone who visited our booth and discussed industrial boiler applications with our team. We look forward to following up on project inquiries, strengthening relationships with business partners, and exploring opportunities to serve more customers in international markets.
