SZL series double drum quick-installed steam boiler

 The body of the SZL series steam boiler is composed of vertical upper and lower drums and convection tube bundles. The left and right sides of the combustion chamber are equipped with light pipe water-cooled wall tubes. The upper drum is equipped with a steam-water separation device and a surface sewage device, and the lower drum is equipped with Regular sewage discharge device. An economizer is arranged at the end of the boiler.

The combustion part of the double-drum quick-installed boiler adopts a light chain grate to realize mechanical coal charging, and is equipped with a blower and an induced draft fan for mechanical ventilation, and is equipped with a screw slag machine to realize automatic slag discharge. The fuel falls from the coal hopper to the grate, After entering the furnace and burning, the flame is refracted through the back arch to the convection tube bundle, passing through the back flue gas outlet into the economizer and dust collector, and then drawn by the induced draft fan through the flue to the chimney and discharged to the atmosphere.



SZL series steam boiler product performance characteristics

  1. This boiler product is divided into two major parts, the upper part and the lower part. The upper part includes the boiler body, the steel frame set and the upper furnace wall, and the lower part includes the coal hopper, the chain grate, the base steel frame, and the lower furnace wall, except for the middle partition. The other parts of the wall are assembled on site except for the masonry. The cast iron economizer and air duct at the tail of the boiler are shipped with the furnace.
  2. The combustion part adopts a light chain grate with air intake on both sides. There are six independent air chambers under the grate, and an air adjustment mechanism is arranged on both sides of the air chamber. The air is blown in by the blower and enters the two-sided air duct at the lower part of the base. , Enter the independent air chamber through the air conditioning mechanism.
  3. The upper furnace wall is assembled by the factory, and the lower furnace wall and front and rear arches are composed of refractory clay brick silicic acid fiber and thermal insulation materials. The fuel enters the furnace from the coal hopper through the coal gate and burns, and the burning cinder falls in the operation of the grate. The slag hopper is discharged by the screw slag machine.
  4. The boiler is equipped with an electric control console. The console is equipped with a boiler thermal parameter display instrument, a drum, an induced draft fan opening indicator, and a remote control button for an electric actuator. The boiler feed water adopts an automatic water supply device and is equipped with an over-temperature alarm device .
  5. The burning coal is suitable for the second-class bituminous coal with low calorific value ≥17750J/Kg, volatile matter>38.5%, and ash content ≤32.4%.

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...
