Features

horizontal hot water boiler

1 Adopting horizontal full wet back structure, the overall layout is compact, beautiful and generous, and high thermal efficiency.
2Using slight positive pressure operation, which effectively improves the combustion intensity of the furnace, makes the boiler of the same capacity smaller, eliminates the air leakage of the furnace and flue of the boiler, and improves the thermal efficiency of the boiler.
3 External-integrated fin-tube economizer, compact structure, convenient maintenance, lower exhaust gas temperature, and improve thermal efficiency.
4Using advanced EDA design technology, detailed calculation of furnace body structure and size, effective control of flue gas flow rate and resistance, reasonable and full use of flame and flue gas heat exchange, and improve the thermal efficiency of the boiler.
5 The application of the corrugated furnace structure not only increases the heating area but also increases the disturbance of the flue gas, and the application of the threaded smoke tube technology increases the convective heating surface.
6. The low-level combustion chamber is designed to keep a larger water level safety space and minimize the hazards of water shortage accidents.
7 Using reasonable structural design and excellent fire-resistant and heat-insulating materials, the surface temperature of the furnace body is greatly reduced, so that the surface temperature is lower than 50 degrees (higher than the national standard), reducing heat loss and improving the thermal efficiency of the boiler.

1. Imported burners from many internationally renowned brands are used to adapt to various application scenarios to ensure quality and safety

2. Using Siemens and other major international brands such as PC and other automation controllers as the control core, and also adopting the peripheral components of international brands to achieve a high-quality automatic control system, which can collect the temperature and pressure of the inlet and outlet in real time. Various parameters are displayed centrally in the control cabinet in real time. Through closed-loop control systems such as PD, the boiler can be ensured to work stably under various parameters set by the user. At the same time, the working range of the data is monitored, and various abnormalities can be reminded or alarmed, which is convenient User use and maintenance. The control module also has powerful expansion capabilities. According to customer requirements, it can easily realize multiple in-depth applications such as group control and remote control.

      Features 1. The drum is composed of arched tube sheet and threaded smoke tube. The pot shell is changed from quasi-rigidity to quasi-elasticity to prevent cracks in the tube sheet. Compared with the flat tube sheet, the arched tube sheet has better deformability, which reduces the damage of the tube sheet caused by the thermal expansion and contraction of the pipeline. 2. There is a baffle plate in the boiler header, which increases the heat e...
