3, Structure

1) The boiler cycle is a natural circulation circuit;
2) Boiler heating elements: The designed heating elements of the boiler are divided into corrugated furnace, flat furnace, furnace head, and convection tube bundle. The corrugated furnace, the flat furnace and the furnace head are radiation heating surfaces, and the convection tube bundle (threaded tobacco tube) is a convection heating surface. The shape of the corrugated furnace is φ600mm, the length is 1380mm, the diameter of the straight furnace is φ600mm, and the length is 450mm, which is the radiation heating area. The pipe convection tube bundle is: long pipe φ51×3mm, length 2815mm, number 26; thread pipe is φ51×3mm, length is 2030mm, number is 36, and both convection heating area.
3) The boiler is designed with a tail heating surface as a fire tube economizer, a threaded cigarette tube φ51×3mm, a length of 1200mm, and a number of 26.
4) Boiler combustion equipment: The boiler combustion equipment is an imported automatic burner.

5, Performance characteristics:

The 1ton gas fired steam boiler has increased the convective heating area based on the thermal calculation standard design, and meets or exceeds the rated output. The safe and stable operation condition of the boiler should be within 70%~100% load; the exhaust gas temperature is lower, the boiler efficient high.

Suitable furnace size, unfolded flame, adapt to a variety of gas burners.

The boiler has control and protection functions such as automatic ignition, program control, water level control, overpressure protection, and furnace flameout protection. It is easy to operate, safe and reliable.
