Gas fired steam boiler for double drum, longitudinal type, “D” type layout structure, the right side of the furnace, the left side of the convection tube bundle, superheater layout of the convection tube bundle area; The movable supports at both ends of the lower drum are fixed on the body chassis, and the boiler is expanded to both ends as a whole. The membrane type water wall is around the furnace of gas fired boiler manufactuing, and the membrane type water wall on the left side of the furnace is completely sealed and separated from the convection tube bundle. The back part of the convection tube bundle area is a slurred staggered structure, and the front part is a aligned structure. The flue gas generated by combustion in the furnace enters the combustion chamber and convection tube bundle area from the smoke outlet at the end of the furnace. Then it turns from the front left side of the boiler into the spiral finned tube energy saver and condenser, and finally into the flue.

The high temperature area of 30 Tons steam boiler body adopts forced circulation to ensure that the heating surface of each part can get reliable cooling and prevent vaporization. The boiler is equipped with explosion-proof door and flame detector to ensure safe and reliable operation. Both sides of the boiler membrane wall and the cylinder between the seal all adopts comb plate, to eliminate the use of refractory concrete seal caused by condensate water and gas leakage. Air tightness inspection before leaving the factory to ensure no slight leakage of gas.

Gas fired boiler manufactuing is reasonable, the boiler has a larger furnace, with a low emission combustion machine, NOx as low as 30mg/Nm3. The gas steam boiler flue and boiler flue gas outlet adopt internal insulation measures, effectively reduce the noise in the boiler operation. Combustion chamber adopts the whole film type water wall structure, using the micro positive pressure combustion, no smoke problem, no pollution in the operation environment. Manholes are arranged before and after the upper and lower drum, and inspection doors are arranged at the back of the boiler, which are convenient to open and conducive to user maintenance and cleaning inside and outside.

This series of steam boiler is made of high quality aluminum silicate fiber, and then heat preservation with refractory mud. The temperature of the furnace body is controlled below 45℃, and the heat loss is effectively controlled. The combustion chamber of industrial gas fired boiler adopts narrow distance tube membrane type water wall, which has good air tightness, reducing heat loss and improving boiler thermal efficiency. The inside of the observation hole adopts formed high aluminum refractory material and sealing device of manhole cover, which has changed the problem of overheating caused by the use of firebrick masonry.

The front and rear walls of the boiler body are all membrane structure, greatly improving the service life of the front and rear walls, to ensure that the service life of more than 20 years of steel plate downslope, circle, drum drilling and other key processing technology using advanced numerical control processing technology, reduce the assembly stress, prolong the service life of the boiler. All convection tubes in high temperature area adopt anti-chatter fasteners to prevent the fracture of the nozzle of convection tube bundle. The boiler longitudinal and circumferential seam welding adopts advanced submerged arc automatic welding technology to ensure the welding quality. All longitudinal and circumferential welds are inspected by 100% radiography.

Gas fired boiler manufactuing price is reasonable, the overall design fully conforms to the standard, the use of energy saving and environmental protection. The boiler is equipped with famous and efficient brand burners, auxiliary machines and accessories to achieve automatic operation. Gas steam boiler feed water pump adopts continuous electric regulation, and has high and low water level alarm chain protection function. At the same time, the series of steam boiler furnace with inspection holes, for use, maintenance to provide a great convenience, the top of the furnace is equipped with explosion-proof door.
