Low nitrogen gas steam boiler

A heated boiler is called a boiler. Heat transfer oil, also known as organic heat carrier or heat medium oil, has been used as intermediate heat transfer medium in industrial heat transfer for more than 50 years. Based on the idea of forced cycle design, a once-through boiler is developed. Generally, coal, oil and steam are used as fuel, heat conduction oil is used as the medium, hot oil circulation pump is used to force the medium into liquid phase circulation, heat energy is transmitted to the heating equipment and then returned to the heating furnace for re-heating. High operating temperature at low pressure, and high precision control for medium operation. The heat utilization rate of the system is high, and the transportation and maintenance are convenient. The closed circulation heat supply is connected with the atmosphere, can extend the service life of the boiler, liquid phase or gas phase transportation heating. The boiler adopts three-way coil design, the system sets the expansion water tank, and realizes low-pressure and high-temperature heating. The coil structure is adopted, the heating surface is sufficient, and the expansion is fully absorbed. Imported low-NOX combustion machine, combustion charge, belongs to environmental protection products. Boiler can choose advanced touch screen computer controller and digital computer controller automatic control system. With automatic temperature regulation, automatic ignition, and differential pressure, overtemperature, quenching protection. Boiler manufacturing standards, strictly in accordance with the relevant national standards. Pot The use of furnace water quality requirements: some users believe that as long as the boiler to maintain water can be, the water quality is not a choice. In fact, the quality of water on the boiler or have an impact, the editor recommends that you choose clean tap water. Because if there are impurities in the water, the use of this impurity water will have some impact on the equipment. The impurities form a thick layer of scale on the inner wall of the boiler. Scale will gradually thicken with time, and the accumulation of thickness will affect its heat transfer efficiency, resulting in a waste of energy consumption. If the scale appears, it should be cleaned up in time, so that the heat can be concentrated in the scale, which is not easy to emit. .

Thirteen Five release plan indicates that China's move towards green development pace firmer, Beijing SASAC Building Materials Service Center from its start, the use of green boiler heating for low nitrogen as the primary task before the onset of winter. SAC Building Materials authorities after preliminary investigation and after the screening, the other fast boiler R & D experience in the field of boiler cleaning two decades expressed appreciation can, in August 2017 signed a five Thalia T6 series one boiler and two vacuum with fast Boiler condensing gas boiler products contract.

Matters needing attention in loading and installation of Gas-fired Steam Boiler

Gas-fired steam boilers are a very wide range of special equipment, usually built in boiler rooms. However, in the process of loading and installation, some problems must be paid attention to, otherwise it may cause a certain degree of economic loss.

1. Pay attention to the following matters during the loading and unloading and handling of gas-fired boilers: the lifting capacity of the lifting equipment should match the weight of the lifting boiler. The lifting lug on the boiler with the lifting lugs that cannot be used for lifting can not be used for lifting. The length of the steel cord should be reasonably selected to avoid the scratching of the furnace due to the improper length of the steel cord. The boiler must be protected from any damage during handling and handling.

2. Reserves for maintenance space When installing boilers, ensure that there is sufficient maintenance space around the boiler.

3. Setting and precautions for the base and base of the gas steam boiler The boiler body must be installed on the basis of 100-150mm above the floor of the boiler room. It must be confirmed with the technical personnel of the boiler manufacturing company in advance and constructed according to the basic drawings. The anchor bolts must be reserved on the foundation. The foundation shall be capable of withstanding the maximum weight of the boiler and the amount of water it holds. When installing the base, you must first position it. After positioning, adjust to the same length of the two diagonals of the base, and then tighten all the fixing bolts. The installation of the base is carried out with reference to the reference line.

4, general precautions Be careful not to tilt and impact the boiler and accessories too much. No combustibles can be placed around the boiler. Do not use oil and water to smother the boiler. The boiler should normally be installed in a separate boiler room. The new gas-fired boiler room should not be connected to the house. The boiler room shall not be connected to Class A, Class B and Category C fire hazard rooms using flammable liquids. If connected to other production plants, the application firewall is separated.

2. Oxygen corrosion

For the biomass fuel boiler pressure parts,the water side is mainly electro chemical corrosion,the fire side (or flue gas side) is mainly chemical corrosion.The oxygen corrosion belongs to electrochemical corrosion, it is mainly caused by the dissolved oxygen in water.At room temperature,the dissolved oxygen concentration is about 9.1mg / L,according to the GB1576-2001 “industrial boiler water quality” requirement ,the rated steam pressure should not be more than 1.0MPa,the dissolved oxygen concentration should not be more than 0.1mg / L,otherwise,it is likely to lead to metal corrosion.
