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. Heilongjiang Horizontal 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 Horizontal 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.

The boiler adopts the combustion equipment suitable for the combustion of biomass fuel - reciprocating grate. In the structural design of the boiler, the furnace space of the boiler is larger than that of the traditional boiler, and the reasonable arrangement of the secondary air is conducive to the full combustion of a large amount of volatile matter released instantaneously during the combustion of biomass fuel. The boiler can be equipped with oil (gas) ignition burner to realize ignition automation. Heilongjiang Horizontal gas steam generator The feeding, combustion, slag removal, water supply and ignition of the boiler can be automatically controlled, and the operation is convenient. The boiler is equipped with an automatic ash cleaning device, which can remove the ash on the heating surface of the boiler in time to ensure the efficient and stable operation of the boiler. The tail of the boiler is equipped with an economizer, or an air preheater according to the user's needs. Compared with the traditional boiler, the boiler has higher efficiency and lower exhaust gas temperature. High efficiency thermal insulation materials are used, the boiler surface temperature is low, and the heat dissipation loss can be ignored. vertical Horizontal gas steam generator manufactor All pressure parts are made of excellent boiler steel in strict accordance with Chinese national codes and standards. Each boiler shall be strictly inspected and tested before leaving the factory, including hydrostatic test and X-ray inspection. Manholes, inspection doors, fire observation holes, etc. are set to facilitate maintenance. The major characteristics of biomass boiler are: energy conservation, environmental protection, and easy installation and use.

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. Heilongjiang Horizontal 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 Horizontal 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.

Waste heat boiler is a kind of industrial equipment. Although the equipment is simple to operate, it also needs special attention in practical application. Heilongjiang Horizontal gas steam generator So what should we pay attention to when it runs? Generally, when using waste heat boiler, we need to pay attention to prevent misfire. Due to the excessive output of the burner, the flame will disengage from the burner, resulting in incomplete combustion. A large amount of mixed gas in the furnace may cause explosion, and backfire should also be prevented. Due to the low output, the flame will retract into the burner, resulting in unstable flame flameout vertical Horizontal gas steam generator manufactor If the combustible gas continues to enter the limit, it may cause explosion. After ignition, pay attention to adjust the combustion gas flow, stabilize the burner pressure, so that the flame can burn stably. In order to reduce the smoke from the chimney and pollute the environment, smoke suppression and dust removal devices should be installed.

The air storage tank in the air source system shall be installed behind the rear cooler, so as to prevent oil vapor and liquid water from gathering in the tank and reduce potential safety hazards as far as possible; The lower temperature of other air stored in the tank can also reduce the volume of the body. Heilongjiang Horizontal gas steam generator When connected with screw compressor and other air supply equipment, the air receiver can be installed behind the dryer. At this moment, the air entering the air receiver is dry and there is no condensate in the tank. The air tank is a pressure vessel, and each air tank shall be equipped with safety valve, pressure gauge and other necessary safety supervision equipment. vertical Horizontal gas steam generator manufactor The application and maintenance shall strictly comply with the relevant provisions of pressure vessels; The air tank shall be equipped with a manhole or hand hole for maintenance, and the lower part of the tank shall be equipped with a drain valve, which shall be regularly drained; The air storage tank is usually installed outdoors, so it should be protected from direct sunlight and there should be no high temperature heat source nearby.

The waste heat boiler is composed of drum, movable smoke hood, feeding pipe groove, oxygen lance mouth, furnace mouth section flue, inclined section 1 flue, inclined section 2 flue, last section 1 flue, last section 2 flue, nitrogen sealing device and nitrogen sealing plug, manhole, micro differential pressure tapping device, flue support and hanger. Heilongjiang Horizontal gas steam generator Unlike conventional boilers, waste heat boilers do not produce combustion process and do not have combustion related equipment. Essentially, they are just gas water/steam heat exchangers. The waste heat boiler is divided into six circulation loops. Each circulation loop is composed of downcomer and riser. The feed water of each section of flue is introduced from the drum through downcomer to the lower header of each flue, and then enters into each heating surface. The water passes through the heating surface and generates steam into the header, and then is introduced into the drum through the riser. vertical Horizontal gas steam generator manufactor The needle tube waste heat recovery device is a special high-efficient energy-saving product specially designed for waste heat recovery of flue gas. The heat recovery boiler uses needle shaped tubes to strengthen the heat elements to expand the heating surface. The heating surface on the water pipe smoke side can be greatly increased. At the same time, the smoke will form strong turbulence when passing through the needle shaped tube surface, which will improve the heat transfer efficiency and reduce the soot accumulation.
