Coal Fired Chain Grate Steam Boilers For Sale

 Coal-fired steam boiler is a horizontal single - barrel fire - water - tube chain grate structure. Boiler body adopts a single cylinder longitudinal arrangement, cylinder and two sides of the water-wall tube to form a furnace radiant heating surface. Both sides of the water pipe bundle composed of water pipe convection heating surface. Threaded smoke pipe in the drum to form a fire tube convection heating surface. The tube plate adopts low stress arch tube plate without tensile support. The series steam boiler by the upper body and the lower grate composition, economizer arranged in the back of the boiler.



The chain grate steam boiler has the advantages of compact structure, small occupation area, short installation cycle, less installation cost and less capital investment. The low smoke temperature in the tube plate of the boiler series, the uniform heating of the single return tube plate of the tube plate, the low stress of the tube plate makes the boiler safe and reliable operation, and the service life is long. The heating surface layout of this series of coal-fired boilers is fully reasonable, the boiler temperature rise, fast pressure boost, sufficient output, high thermal efficiency.

This series of boiler products grate air into the air bin, each air bin air volume can be adjusted independently, stepless speed control grate. Adapt to a wide range of coal, full combustion. Electric control cabinet with overpressure, high and low water level alarm and interlocking protection device, safe and reliable, easy to operate. DZL series coal - fired steam boiler manufacturing technology advanced, using automatic spinning line operation. Enhance heat transfer and improve boiler thermal efficiency.



Zozen Boilers specialize in producing various types of boiler products, coal chain grate steam boiler after eight type flue cooling of the flue gas from the front flue box into the threaded tube arranged in the tube (now fire tube). This design solves the cracking problem of tube plate of pure fire tube boiler fundamentally. Welcome to consult and purchase, we will serve you wholeheartedly.

Parameters and technical requirements of 6-ton gas-fired steam boiler for hospital use

 The 6ton gas-fired steam boiler is commonly used in hospitals, and its process requirements are as follows: Natural gas boiler: natural gas → burner → boiler → steam → sub-cylinder → steam point. Tap water constant pressure water supply → water softener → soft water insulation water tank → energy saver → boiler. Hospitals are densely populated places, so the requirements for boiler equipment and suppliers are relatively strict. Suppliers of 6ton gas boilers must have a Class A boiler manufacturing license, a pressure vessel manufacturing license, a Class 2 boiler installation, renovation and maintenance license or above. The equipment supplier shall be responsible for obtaining relevant certificates and fees such as the registration certificate for installation and use of boiler equipment. The water supply of this series of gas boilers is designed with a flue gas condensation recovery device to recover the heat energy of the flue gas, and the exhaust gas temperature is less than...

SZS Gas-Fired Horizontal Water-Tube Saturated Steam Boiler

 The pipelines within the scope of the SZS watertube steam boiler only include the valves and pipelines from the flange of the return water check valve to the outlet valve and drain valve of the boiler body. Accessories include valves and gauges for the boiler body. Such as pressure gauges, air valves, spring safety valves, outlet and return valves, check valves, thermometers, etc. The SZS gas-fired steam boiler is equipped with a flue gas condenser at the tail of the boiler body, which reduces the flue gas temperature (<70°C), improves the boiler efficiency and reduces the harmful components in the flue gas. The boiler adopts micro-positive pressure combustion, and the furnace wall tube is a full-membrane wall structure. This series of boiler products has a certain pressure bearing capacity, and no smoke leakage and air leakage will occur when running under a slightly positive pressure state. The boiler is a self-contained boiler, which can shorten the installation period whi...

35 Tons SZS Gas Steam Boiler

 The SZS gas fired steam boiler is equipped with a flue gas condenser at the tail of the boiler body, which reduces the temperature of the flue gas, improves the efficiency of the boiler, and reduces the harmful components in the flue gas. The szs gas boiler adopts micro-positive pressure combustion, and the furnace wall tube is a full-membrane wall structure. The 35ton gas-fired boiler has a certain pressure-bearing capacity, and there will be no smoke leakage and air leakage when running under a slightly positive pressure state. The boiler is a self-contained boiler, which can shorten the installation period while meeting the transportation size requirements. At the same time, the aluminum casing and the skeleton are transported and connected by bolts, which are convenient for disassembly and maintenance. The furnace of this series of boiler products adopts a model water-cooled wall structure, and the whole boiler adopts an air-tight inner shield with a fully enclosed welding s...
