Introduction of high efficiency natural gas steam boiler
Overview of the high efficiency natural gas steam boiler
Natural gas steam boiler is high efficient, it adopts boiler-shell type corrugated furnace structure, smoke three-pass with a wetback smoke-transfer chamber, and spirally corrugated tube tech. The complete set product of the boiler consists of burners, boiler, control systems, and accessories. This product series is designed to be safe, reliable, efficient, energy-saving, and environmental protection. It also features convenient maintenance, long service life, automatic intelligent control, etc.The structure of the natural gas steam boiler
Why is the boiler high efficiency?
The natural gas steam boiler is high efficiency. The boiler’ thermal efficiency is to increase the effective use of heat and reduce various heat losses of the boiler. The key point is to reduce the heat loss of boiler exhaust and incomplete combustion losses.
★ The structure of the boiler body can improve the efficiency of the boiler, such as the large corrugated furnace, which can make the fuel burn more fully. Compared with incomplete combustion, it can provide higher heat to the boiler and improve the thermal efficiency of the boiler. The threaded smoke pipe can enhance the heat transfer effect and improve thermal efficiency. The double-layer insulation design keeps the temperature of the furnace body below 45°C, reducing heat loss and improving thermal efficiency.
★ The burner can adjust the feed fuel and air ratio. When the ratio of natural gas and air is 1:10, the fuel can be completely burned, providing enough heat for the boiler to use, thereby improving the thermal efficiency of the boiler.
★ The automatic control system by PLC, PLC+PC control, DCS control can monitor the operating status of the boiler in real-time and issue signals in time so that the boiler can operate efficiently , indirectly improving the thermal efficiency of the boiler, and reduce the loss of fuel and heat caused by untimely control
★ Increasing the inlet water temperature or inlet air temperature of the boiler can also improve the thermal efficiency of the boiler. We provide customers with air preheaters or condensers to choose from.
Efficiency isn’t just about saving energy and money; it’s also about being green and reducing emissions. With all the talk and concern about global warming, having a low emission boiler is more important than ever. With steam boilers, one of the biggest emissions standards is the number of harmful nitrogen oxides (NOx) that get sent into the atmosphere. When a gas boiler is considered “low NOx” or “ultra low NOx,” it means it burns fuel at lower temperatures and releases far fewer of these harmful agents into the air. You might say it’s a “green” boiler and that’s why environmentally conscious companies prefer high efficiency natural gas steam boilers and why you should care about your own boiler’s NOx emissions.
Three pass flue gas of the steam boiler as follows
• The first pass--corrugated furnace
The operation of the boiler is automated. After the fuel is atomized by the burner, the torch formed fills the full corrugated furnace and transmits radiant heat through the furnace wall. This is the first return journey.
• The second pass--short threaded smoke tube
The high-temperature flue gas generated by combustion gathers in the re-combustion chamber and turns to enter the second return journey, that is, the flow of the threaded smoke pipe bundle area.The thread smoke pipe can
enhance the heat transfer effect and improve thermal efficiency.• The third pass--long smoke tube
It enters the smoke pipe through the front smoke box, and after convection, the temperature of the flue gas gradually decreases, then flows into the chimney through the economizer and condenser, and finally is discharged into the atmosphere.
Features of the gas steam boiler
★ The combustion chamber adopts the corrugated furnace, which reduces the thermal stress and improves the safety of the boiler;
★ The boiler body adopts a wet back structure, which is safe and reliable;
★ The threaded smoke pipe enhances heat transfer and reduces the steel consumption of the body;
★ The boiler is fully automated, with automatic operation and interlock protection functions, and easy to operate;
★ The rear of the boiler adopts a spiral fin tube economizer, which reduces the exhaust gas temperature and has high thermal efficiency. The design efficiency is more than 90%, and the design efficiency of the condenser is more than 95%.
★ Boiler is the horizontal layout, compact structure, small footprint;
★ The front and rear smoke boxes are easy to open, which is convenient for users to check and clean;
★ The flue gas side seal adopts a labyrinth double structure, the flue gas is not easy to leak, and the boiler room is clean and hygienic;
★ The boiler is shipped from the factory as a whole, which is convenient for transportation and a short installation period;
★ According to different burner configurations, the boiler can burn heavy oil, light oil, natural gas, liquefied gas, and other fuels, and the burner can be controlled by position control and proportional adjustment.

System of the natural gas steam boiler
Composition of natural Gas Boiler System
• Combustion system
• Steam water system
• Control system
• Combustion system of the natural gas steam boiler
The combustion system supplies fuel to the boiler for heat generation.
Gas fired steam boilers' combustion system equips with a burner and fuel device according to the fuel properties, steam capacity, and pressure of the boiler.
Burner brands: Baltur, Riello, Weishaupt, Hofamat, Honeywell, Ecoflam, Cavallo, and so on.
• Steam water system of the natural gas steam boiler
The steam water system consists of a feedwater part and a steam part.
Feedwater part: Feedwater refers to the water that is provided to the boiler for steam conversion. The feedwater channels water into the boiler and automatically controls it to satisfy steam requirements.
Steam part: the steam is the part of the boiler responsible for collecting and regulating the steam generated by the boiler. Valves and pressure gauge controls are used to monitor and regulate steam pressure.
The steam and water system should be composed of the boiler's main body, rear heating surface(such as economizer, condenser and so on which are equipped according to the actual situation of the user), water treatment device, feedwater pump, steam header, deaerator and so on.
• Control system of the gas steam boiler
The boiler control system is a collection of boiler electrical control components, a center for collecting and processing boiler operating signals, and an operation platform for sending execution instructions to each execution unit of the boiler.
If you want the boiler system to realize the IoT(Internet of Things) service for the boiler system, we can provide you with this service when designing the control system.
The IoT system for boiler system adopts a layered structure design, namely data collection layer(M BOX), cloud platform(M SERVICE), and application layer(MYZT application system).
Control principle: Through the real-time data collection, monitoring, and processing of boiler water level, pressure, flue temperature and burner, the purpose of intelligent, and safe operation is achieved.
