The main structure of the gas-fired steam boiler is a horizontal internal combustion wet-back three-pass fire tube boiler. The horizontal gas fired boiler is composed of boiler body, burner, heat pipe economizer, steam and water pipeline, valve instrument system, automatic control cabinet and other components. The combustion efficiency of the burner is over 98%.
This series of boiler fuel is injected into the furnace bladder through the burner and burns. The high-temperature flue gas generated in the furnace radiates heat exchange and enters the second return smoke pipe group through the rear turning smoke chamber, and then goes to the front smoke box after convection heat exchange. And then turn 180. After entering the third return smoke pipe area to the rear smoke box, the heat pipe economizer enters the chimney and is discharged into the atmosphere. The feed water is pressed into the drum by a water pump through a check valve, etc. The water is heated in the boiler and evaporates. The pressurized steam is led from the main steam valve through a steam-water separator and sent to the user’s steam-using equipment.
The horizontal gas fired boiler adopts a horizontal three-pass wet back structure, which improves the operating environment of the boiler and improves the combustion efficiency and service life of the boiler. This series of boiler products adopt a corrugated furnace liner and a threaded smoke tube. The size of the furnace liner is consistent with the flame. The flue gas flow area is sequentially reduced, so that the flue gas flows at the same speed, and the heat exchange time of the high temperature flue gas in the furnace is Good heat transfer effect.
It uses a burner to fully burn fuel and save fuel, thereby effectively reducing environmental pollution caused by boiler combustion. The gas fired boiler adopts ultra-fine glass wool with high heat preservation performance, so the heat dissipation loss is smaller. Adopt intelligent PLC control system, intelligent operation, simple and convenient. The installation of the boiler adopts the integral quick installation method, there is no special requirement for the foundation, no anchor bolts are needed, and the installation is simple and easy. With the movable burner structure, not only can it be matched with various burners, but it is also more convenient and quicker to replace the burner and repair the furnace body.
Gas series boilers can not only burn natural gas, biogas, liquefied gas, coal gas and other single fuels, but also mixed gases. Many customers who know about boilers before purchasing should know that the four essential conditions required for boiler design are the applicable fuel selected by the customer, and what this requirement ultimately requires is the calorific value of the gas. Generally speaking, even if the calorific value is very low, it can be designed. But not all gas mixtures are suitable. This requires our boiler designers to have a detailed understanding of customer needs.
The thermal efficiency of a horizontal gas fired boiler is a consideration factor in choosing a boiler, but it is not the only one. The large space in the combustion chamber of this series of boilers greatly reduces the emission of harmful components in the flue gas. Tested by the environmental protection monitoring department, the blackness of the exhaust gas emitted by the company’s gas fired steam boiler is lower than the Ringelmann blackness, which meets the requirements of environmental protection and is an ideal environmentally friendly product.
