summary
In order to meet the needs of market changes, we have designed a series of shell type steam boilers that are condensing, low nitrogen, energy-saving, and environmentally friendly based on the structural characteristics of several types of shell type boilers; This series of boilers has a beautiful and novel appearance, compact and reasonable design, stable combustion, good performance, high thermal efficiency, and fully automatic control.
This series of steam boilers is designed with environmentally friendly clean fuels - fuel oil and gas, and complies with various professional manufacturing standards such as TSG G0001-2012 "Boiler Safety Technical Supervision Regulations" and JB/T10094 "General Technical Conditions for Industrial Boilers".

Boiler model
According to JB/T1626-2002 "Method for Model Compilation of Industrial Boiler Products".

Boiler system
The fully automatic fuel (gas) steam boiler (vertical) adopts a wet back fire tube chamber combustion structure. We have effectively solved the problems of enhanced heat transfer, heat loss, adaptability to load changes, reasonable sealing and structural expansion and contraction of the boiler. The fuel burns under slight positive pressure in the furnace chamber, and the high-temperature flue gas undergoes radiation heat transfer along the furnace chamber. It then turns 180 ° backwards to the top of the furnace chamber and flows back downwards in the large space furnace chamber for radiation heat transfer. It enters the threaded smoke tube bundle for convective heat transfer, and then enters the smoke chamber, where it is discharged into the atmosphere through the chimney. This series of boilers has a compact and reasonable structure, a long operating cycle, and easy installation, maintenance, and operation. Equipped with imported burners and boilers, fully automatic program control and interlock protection, high degree of automation, high thermal efficiency, meeting user requirements.

2) The upper part of the boiler is equipped with a manhole device, and the lower part is equipped with a handhole for easy maintenance and upkeep.
3) This boiler uses centrifugal glass wool as insulation material, which has good insulation performance, light weight, and easy transportation and installation.
4) Equipped with imported burners and boilers, fully automatic program control and interlock protection, high degree of automation, high thermal efficiency, meeting user requirements.
5) Automatic control: Pressure control, water level display, water level control, and temperature control are all program controlled. Digital temperature display and control ensure safe operation of the boiler, making it easier to use, operate, and maintain.
6) The strength calculation of the main pressure bearing components of this boiler conforms to the specifications to ensure user safety.
7) The manufacturing of this series of boilers shall be carried out in accordance with the requirements of JB/T1619-2002 "Technical Conditions for Manufacturing Shell Boiler Bodies", fully complying with national standards.

Electrical control
This series of boilers adopts a PLC automatic control system. The control system uses PLC as the control and data acquisition core, inputting the overpressure protection signal of the pressure controller, the water level control detection signal of the water level sensor, the extremely low water level detection electrode signal, the ultra-high water level detection electrode signal, the motor protection detection signal of the feedwater pump, and the various signals and overpressure protection signals of the pressure transmitter controlling the burner, making it rich in artificial intelligence and ensuring the safe and reliable operation of the boiler.
