Steam Boiler Specification

Structural characteristics

1. Adopt horizontal full wet back structure, compact overall layout, beautiful and generous, high thermal efficiency.

2. Adopt micro-positive pressure operation, effectively improve the combustion intensity of the furnace, make the volume of the same capacity boiler smaller, at the same time eliminate the boiler furnace, flue air leakage, improve the thermal efficiency of the boiler.

3. External integrated finned tube economizer, external independent condenser, compact structure, easy maintenance, the use of the current more popular condensation technology, reduce the smoke exhaust temperature, improve thermal efficiency.

4. Adopt advanced EDA design technology, calculate furnace structure and size in detail, effectively control flue gas velocity and resistance, reasonably make full use of flame and flue gas heat exchange, improve boiler thermal efficiency.

5. The corrugated furnace structure not only increases the heating area but also increases the disturbance of the flue gas, and the threaded flue gas technology increases the convection heating surface.

6. Use frequency conversion water supply and control technology to ensure the condensation rate of water vapor in the flue gas.

7. The condenser adopts special steel with "low dew point corrosion resistance of sulfuric acid", which greatly improves its service life.

8. Adopting reasonable structural design and excellent fire-resistant and thermal insulation materials, the external temperature of the furnace body is greatly reduced to make the external temperature below 50 degrees (higher than the national standard), reducing heat loss and improving the thermal efficiency of the boiler.

9. Adopt a new design to reduce the emission of harmful substances during fuel combustion and meet the national environmental protection standards, especially the emission of nitrogen oxides, and meet the national low nitrogen emission standards.

10. Imported burners from many international famous brands are adopted to adapt to various application scenarios to ensure quality and safety.

Boiler Executive Standard

1. Design, manufacture, assembly, experiment and acceptance of boilers in strict accordance with national and industrial standards, including but not limited to the following standards: GB/T16508 Boiler Shell Boiler, TSG G0001 Boiler Safety Design Supervision Code, GB50273 Boiler Installation Engineering Construction and Acceptance Code

2. The main steel used in the boiler is 20 GB/T3087, which ensures the safety and reliability of the boiler.

3. Welding materials shall be selected according to NB/T47018. Full penetration welding with argon protection shall be performed on the boiler tube.

What are the available fuel for the oil gas fired boiler?

Oil gas fired boiler could burn both liquid fuel and gaseous fuel. The liquid fuel could be heavy oil, light oil, diesel, furnace oil, bunker oil, LPG (liquefied petroleum gas), etc. The gaseous fuel could be natural gas, city gas, bio-gas, etc.

Whether the boiler can burn dual fuel or multi-fuel?

Jinzhen boiler have oil burner, gas burner, and oil&gas dual fuel burner, we can offer the specific burner based on customers’ requirement.

What is the texture of spirally corrugated tube?

The texture of spirally corrugated tube is 20#.

The brand of burner?

The brands of burner are Italy Baltur, Rellio, Elco, etc.

What is the thickness of combustion chamber?

the thickness of corrugated furnace is different based on working pressure and furnace diameter, generally, the thickness is between 10~18mm, large combustion space, and combustion sufficient.

What is the advantages of fire tube boiler?

This fire tube boiler has compact structure and convenient operation, strong load adaptability, lower water quality requirement, and the failure rate of it is lower than 0.1!

Details of electric control cabinet.

Electric control cabinet adopts PLC touch screen, display in English. It shows working condition details of boiler, such as water temperature, water pressure, exhaust gas temperature, and over-pressure alarm, etc. In addition, the cabinet is used for set up the parameter, record and analyze the operation data, etc.

What is the inlet pressure of gas burner?

The inlet gas pressure is different for different capacity boiler, for example, the pressure for 2 ton steam capacity boiler is about 8~10KPa, while for 4 ton steam capacity boiler is about 18~20KPa.

What is the combustion mode of oil gas fired boiler?

The combustion mode of oil gas fired boiler is chamber combustion. Together with air, the powered fuel (solid fuel - coal dust), atomized fuel (liquid fuel - oil), and vaporized fuel (gas fuel - natural gas) is sprayed into furnace (combustion chamber) for suspension combustion.

Differences between fire tube boiler and water tube boiler.

What tube boiler also called shell boiler, the flue gas flows in fire tubes or smoke tubes, and heat the water, steam or the steam-water mixture outside the tubes. Compare with the water tube boilers, fire tube boilers have relatively smaller steam capacity, between 0.5~20t/h, and working pressure is between 0.7-1.6Mpa. This fire tube boiler has compact structure and convenient operation, strong load adaptability, lower water quality requirement.

Water tube boiler refers to the boiler that water, steam or the steam-water mixture flows in the tubes, and fire or the smoke are combustion and flow outside the flues. Compare with fire tube boilers, water tube boilers has the features of larger steam capacity and pressure, better heat transfer property and higher combustion efficiency, otherwise, the requirement on water quality is higher.

Difference between wet back and dry back structure.

Wet back structure refers to the drum, tube plate, and backboard in reversal chamber are surrounded by water. It can adapt to the high temperature, and has a good sealing, at the same time, it increase the radiation heat transfer area and improve the heat transfer efficiency. While, there is no water interlayer in the dry back boiler, and the backboard of reversal chamber is composed of refractory material, it is easy damaged by the high temperature.

The requirement of gas-fired steam boiler for local atmospheric pressure

Required environment: 20℃, 1013.25mbar.

When select the model, the environment condition (temperature and elevation) should be considered, correct the burner output curve when the environment condition is different.
