Biomass Steam Boiler Introduction

 Biomass fired boiler fuel sources are extensive, is a renewable green energy, it almost does not contain sulfur content, ash content is less, its growth process can absorb all CO2 produced by the combustion process, achieve CO2 zero emission. Biomass energy will gradually replace coal and become one of the main energy sources.



Biomass Steam Boiler Characteristics

  1. The pot barrel is composed of arched tube plate and threaded smoke pipe, so that the pot barrel changes from a quasi-rigid body to a quasi-elastic body structure, and the stretch parts in the tube plate area are eliminated to reduce the stress. The smoke pipe in the tube plate is changed from two return journey to single return journey, which solves the problem of crack in the tube plate.
  2. The bottom of the pot is arranged with an ascending pipe row, which eliminates the stagnant area at the bottom of the pot and makes the mud residue not easy to deposit. The high temperature area of the pot can be well cooled to prevent the bottom bulge of the pot.
  3. High efficiency heat transfer threaded smoke pipe is adopted to enhance the heat transfer effect and achieve the characteristics of boiler heating up and boosting fast, thus improving the thermal efficiency of the boiler.
  4. Compact structure, compared with the same type of boiler, small external size, saving investment in boiler house infrastructure.
  5. Stable operation, convenient adjustment and sufficient output.
  6. The use of threaded smoke pipe to enhance heat transfer, improve the heat transfer coefficient and thermal efficiency, because the smoke in the pipe has a disturbance. Smoke tube is not easy to accumulate ash, play the role of cleaning.
  7. The eight-character wall in the furnace and the smoke window at the exit have a certain dust-lowering effect. The original dust concentration of the boiler is controlled below the standard to ensure that the soot emission of the boiler can meet the target of environmental protection regulation.
  8. The unique double-layer secondary air design improves the ignition condition of biomass fuel, adopts independent air chamber, achieves reasonable distribution of air, forms an aerodynamic field conducive to combustion in the furnace, and makes the combustion temperature and combustion efficiency high.


The biomass fired steam boiler secondary air in the furnace is designed to disturb the dynamic working condition of the flue gas, so as to supplement the oxygen combustion volatiles in time, improve the thermal efficiency and reduce the emission. Reasonable design ensures the protection of arch and rear grate and avoids periodic micro-explosion in the furnace. For waste material containing water, increase the length of preheating section, provide effective heat source for heating or directly put into hot flue gas high-temperature section. Zozen Boilers 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...
