SZL Series Coal Fired Steam Boiler Introduction

 SZL series coal fired steam boiler is a horizontal double-pot tube water-tube boiler with longitudinal arrangement. Both sides of the furnace are equipped with water cooling walls of dense exhaust pipe and two groups of convective tube bundles are arranged at the rear. The whole boiler is divided into two large parts leaving the factory. After the site is in place, the lower furnace arch and furnace wall are masonry. Chain grate with mechanical balanced ventilation combustion. Stoker's labor intensity is small.



SZL Series Coal Fired Steam Boiler Performance

  1. Divided into the upper and lower body assembly, less investment, fast installation. Single layer layout, small space.
  2. Whole water pipe structure, fast heat transfer and high thermal efficiency.
  3. Chain grate, sectional air supply, large furnace arch cover, fast combustion speed, wide fuel adaptability.
  4. The furnace arch adopts the momentum method design, the flue gas in the furnace in the high temperature area to form a strong turbulent mixing, so that full combustion period, combustion efficiency up to 83%. The emission of soot is much lower than the national standard, which can meet the environmental protection requirements of Class I regions.
  5. The furnace grate stepless speed change control, combustion regulation flexible.
  6. Beautiful appearance, style.
  7. Double-pot tube full pipe structure, mature structure; Convenient inspection and maintenance, short maintenance time.
  8. Mechanization, high degree of automation.
  9. According to the fuel characteristics to change the furnace arch structure, so that it reaches the best state.


This series of coal fired boilers adopt unique pyrolytic gasification and turbulent mixed combustion technology in the furnace structure design, so that the boiler has no black smoke emission. Centrifugal separation, gravity separation in the furnace, plus separation dust in the flue, so that the boiler smoke emissions are small.

Chain grate boiler coal adaptability, high thermal efficiency, energy saving and consumption reduction, in line with China's energy policy; At the same time, the uniform exhaust air distribution, no air flowing between the air chamber, can control the excessive air coefficient required for combustion below 1.2, reduce the generation of CO2 and NOx, improve the combustion effect of the chain grate boiler, improve the combustion efficiency of the boiler, reduce the smoke emission of the boiler, in line with China's environmental protection policy. The assembling boiler can realize the single-layer layout of boiler room, which saves the capital construction investment and is very popular among users.

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...
