The hardness of water is mainly formed and expressed by calcium and magnesium, so cation exchange resin (water softener) is generally used to replace Ca2+and Mg2+(the main component forming scale) in the water. With the increase of Ca2+and Mg2+in the resin, the efficiency of the resin to remove Ca2+and Mg2+gradually decreases. Shaanxi Natural gas steam generator When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to wash the resin layer with salt water in the salt tank to replace the hardness ions on the resin. With the regeneration waste liquid discharged out of the tank, the resin will resume its softening and exchange function. vertical Natural gas steam generator manufactor Because the hardness of water is mainly formed by calcium and magnesium and represents that the hardness of water is mainly formed by calcium and magnesium and represents the principle of sodium ion exchange softening treatment, which is to exchange the hardness components Ca2+and Mg2+in the water with the Na+in the resin by passing the raw water through the sodium cation exchange resin, so as to absorb Ca2+and Mg2+in the water and soften the water.

High efficiency operation: adopt the design of multiple flue gas backflow, optimize oxygen enrichment for many times, cooperate with professional dust removal and energy saving equipment, the thermal efficiency reaches more than 90%, and can continuously produce steam. Low carbon and environmental protection: Through reasonable design, biomass fuel is semi gasified and burned, and smokeless combustion is achieved. Reliable security: It is equipped with pressure, water shortage, security valve and other protection devices to ensure stable operation and reliable security of the boiler. vertical Natural gas steam generator manufactor Simple operation: microcomputer intelligent one button operation, automatic feeding, automatic ignition, cycle start stop and fault alarm functions are used for simple operation. The labor intensity is greatly reduced, and the use of the boiler is more humanized. Convenient maintenance: the overall structure of the boiler is reasonable, and the installation is convenient. There is a cleaning port under each furnace. The main components have inspection ports for future maintenance and repair.

System oil drainage: circulate the heat transfer oil between 120 ± 5 to drain the heat transfer oil in the system (if you do not replace the oil, please find a clean container to store it properly). Prepare an appropriate amount of coke removal cleaning agent for the heat transfer oil system, drain the oil in the gas-fired heat transfer oil boiler system, and disconnect the cleaning system from the oil storage tank (close the valve), including the connection between the high-level tank and the oil storage tank. Shaanxi Natural gas steam generator Residual oil blowing steps: connect the air compressor at the pressure gauge or other places that can be connected, boost the system to 0.3-0.4MPa, and discharge it instantaneously; Repeat this process until the residual oil is blown out. The gas-fired heat transfer oil boiler, circulating pump, and other heat users form a cleaning circulating circuit for decoking and cleaning: add diluted cleaning agent to the system and fill it up to 1/2 of the water level of the high-level tank. Dosage of coke removal cleaning agent: 10~20%, the specific dosage shall be determined according to the scale thickness. Temperature: 90-95, time: 12-72 hours, which can be determined according to the scale thickness. Rinsing and cleaning: after cleaning, drain the residual liquid in the system and add clean water to rinse twice until the coke remover is free of foam and the water is clear. vertical Natural gas steam generator manufactor Temperature: 85-95, time: 5-8 hours Water blowing steps: after cleaning, connect the air compressor at the pressure gauge or other places that can be connected, use compressed air to boost the system to 0.3-0.4 MPa, and vent at each low point. Repeat this process until the water is blown out. Waste liquid treatment: the cleaning waste liquid generated in the cleaning process is discharged after being treated in the biochemical tank.

The furnace liner is the combustion chamber of the horizontal gas-fired heat transfer oil furnace. The burner nozzle is placed in the front of the furnace liner, and the high-temperature flue gas generated by combustion extends to the rear, leaving the furnace liner and returning to the space. Generally, the number of times of returning is not more than four, and the common one is the three return heat conduction oil furnace. Shaanxi Natural gas steam generator This type of heat transfer oil furnace can be divided into dry back type heat transfer oil furnace and full wet back type heat transfer oil furnace according to the structure of the flue gas reentry space at the rear of the furnace. The flue gas reentry space of the dry back heat conduction oil furnace is enclosed by refractory materials; The flue gas reentry space of the full wet back type heat conduction oil furnace is composed of a recuperative chamber immersed in water. In addition, there is a central regenerative heat conduction oil furnace: that is, the back wall of the furnace liner is sealed inside the boiler shell, and the flue gas is turned back to the front from the inner wall around the furnace liner after encountering. This type of heat transfer oil furnace can also be regarded as a full wet back heat transfer oil furnace. vertical Natural gas steam generator manufactor Although the dry back heat transfer oil furnace is simple in structure, the refractory material at the rear of the furnace liner is easily damaged, and the rear tube plate is often directly washed by high temperature flue gas. The temperature difference is large, so the dry back heat transfer oil furnace is obsolete. At present, few manufacturers produce it; Although the full wet back heat conduction oil furnace has a complex structure, it avoids the problem of flue gas sealing in the reentry space and is suitable for micro positive pressure combustion.

The flue gas waste heat recovery device also has the following characteristics: 1. Energy saving. It uses new heat exchange fins and heat exchange elements to make heat exchange more fully, and the exhaust gas temperature can be reduced to 40 ℃~80 ℃; The boiler efficiency can be increased by 6~15%, and the condensate drainage structure can fully recover the latent heat in the flue gas, with remarkable energy-saving effect. Shaanxi Natural gas steam generator Due to the special structure, the total pressure drop is small and the power consumption is small, that is, the smoke pressure drop is small and meets the system requirements. 2. Beautiful. Due to the use of efficient heat exchange elements and reasonable structural configuration, this product has the characteristics of compact structure, small size, beautiful appearance, etc. vertical Natural gas steam generator manufactor Durable. The heat exchange tube of the flue gas waste heat recovery device is made of stainless steel aluminum fins for efficient anti-corrosion. The thermal stress, anti-corrosion performance and strength are fully considered when the equipment is manufactured, which can ensure the safety, reliability and stability of the equipment, with a service life of more than 25 years.

Biomass boilers need green new energy. Compared with other boilers, biomass boilers have the following four major advantages: one boiler is multi-purpose, and can cook, boil water, and bathe while heating. Strong conversion system, low starting heat transfer temperature and fast heat transfer speed. Shaanxi Natural gas steam generator Low installation cost, safe heating: the equipment is universal, without changing the original heating equipment, and the pipes and radiators are universal. Water circulation is used to achieve a wide range of heating materials, which will never be exhausted. It can be taken everywhere (such as rice husks, corn stalks, rice stalks, wheat). Safety and environmental protection: low working pressure, cooking, water boiling, bathing, heating, etc., and it is also suitable for burning boilers, greenhouse heating Large area heating and small and medium-sized hotels can be used all year round without seasonal restrictions. vertical Natural gas steam generator manufactor The reason why the ignition of biomass boiler is difficult is that the stable small fire signal cannot be established, which is caused by the failure of the small fire detector to detect the fire normally. The flame detector for small fire is ionization type flame detector, which requires a contact area with the flame, stable flame size, and gas pressure controlled within a strict range.
