fuel oil boiler

Excellent supplier double drum szs hot water boiler with multi-fuel(gas/oil/coal) for biological engineering industries


SZS series steam boiler produced by our company, the fuel enters the burner from the external air source, and automatically generates high-temperature flame through automatic regulation and ignition function.

The front end of the furnace enters the convection heating surface on the upper side of the burnout chamber, and then enters the second part through the upper part of the front smoke box.

The exhaust gas from the combustion leaves the boiler at the back of the smoke box and is released into the atmosphere.If smoke is improperly generated as a result of the adjustment of the wind, it can be set separately at the first, after, in, and the inspection door can be completely cleaned.

By heating to produce saturated steam, the working fluid is output from the main steam valve to the operating system.


1. Modular design
Boiler as a whole is divided into the body and economizer and other accessories, the body is composed of furnace and single loop convection heating surface, economizer transportation, the whole factory, to ensure the quality of the boiler.Small positive pressure combustion, smoke wind resistance is small.Boiler smoke, air system only equipped with blower, furnace chamber in micro positive pressure, reduce boiler leakage, improve boiler efficiency.
2. Membrane water wall sealing structure
The boiler body and all around the furnace are membrane type water cooling wall, so that the furnace wall can be reliably sealed to prevent smoke leakage.At the same time, it adopts light furnace wall, reliable operation, small heat loss, small thermal inertia, easy to realize quick start and stop.

3. Safe water circulation design
Steam boiler water circulation USES natural circulation loop, water circulation flow resistance is small, there will be no stagnation, back flow, free liquid level and other water circulation condition deterioration phenomenon, effectively prevent pipe explosion accident.Forced circulation loop is used in water circulation of hot water boiler to ensure the safety of water circulation.
4. Safety precautions
The membrane water wall is adopted to improve the rigidity of furnace and flue and the anti-explosion ability of boiler wall.Explosion-proof door is set in the explosion-prone part to prevent the destruction of the furnace wall caused by deflagration.
5. Good configuration of combustion system
Choose the famous brand burner with superior performance, high efficiency combustion, reduce the mechanical incomplete combustion loss, chemical incomplete combustion loss, achieve low oxygen combustion, reduce excess air, reduce the smoke exhaust temperature as far as possible, reduce the heat loss of smoke exhaust, improve the boiler thermal efficiency, and save the operation cost to the maximum.
6. Advanced automatic control system
Company has the best automatic control boiler industry technical ability, adopt the automatic combustion proportional control, three impulse water supply automatic control system, program start-stop, fully automatic operation and other advanced technology, and has high and low water level alarm and low water level, high steam pressure, remove from heat, gas leakage, such as automatic protection function, to ensure the safe and stable operation of the boiler equipment.
