Industrial Boiler For Sale

  YYQW gas fired thermal oil boiler is a new type of special boiler, also known as thermal oil boiler, with low pressure and high temperature working characteristics, and its heating temperature can reach 340°C in liquid phase or 400°C in vapor phase. Any process that requires uniform and stable heating and does not allow direct flame heating can be used in various production occasions where the heating temperature is between 150 ℃ and 380 ℃, and organic heat carrier can be used for heating.  The horizontal gas-fired thermal oil boiler uses gas as fuel and heat-conducting oil as the medium. The heat oil circulating oil pump is used to force the medium to circulate in the liquid phase. The heat energy is transferred to the heating equipment and then returned to the heating furnace for reheating. Obtain a high working temperature, and can carry out high-precision control of the operation of the medium. This series of thermal oil boiler system has high heat utilization rate. Du...

 The horizontal gas-fired steam boiler adopts the corrugated furnace bladder and the re-combustion chamber for one return, the second and third returns are threaded smoke tubes, and an energy saver is arranged on the boiler. The boiler is equipped with complete automatic control devices and safety protection devices with high and low water level alarms and low water level interlocking protection functions; automatic ignition of the boiler, automatic adjustment of the burner power and flameout protection to ensure the safe operation of the boiler. The fuel of this boilers product is light oil or natural gas; the fuel is ejected from the burner, ignited by the electronic ignition rod, and burned in the furnace with slight positive pressure. The high-temperature flue gas after burning is turned 180° into the second, The three-pass threaded smoke pipe turns 180° from the upper part of the rear smoke box into the economizer for heat exchange and is discharged into the atmosphere throug...

 Today, gas-fired boilers , especially low-nitrogen gas-fired boilers have been greatly recognized. Among them, gas-fired steam boilers are more widely used than gas-fired hot water boilers, including food plants, chemical plants, building materials plants, steel plants, etc. Whether light industry or heavy industry is inseparable from steam boilers, let’s take a closer look at the principle and structure of gas-fired steam boilers today. 1. The working principle of gas steam boiler: The heat released by the combustion of fuel in the gas steam boiler in the furnace heats the water in the boiler and vaporizes it into steam. The water in the pot (drum) is continuously heated by the energy released by the combustion of gaseous fuel in the furnace, and the temperature rises and produces pressurized steam. Because the boiling point of water rises with the increase in pressure, the pot is sealed and steam The expansion inside is restricted to generate pressure to form thermal power (str...

  DZL series steam boiler is composed of main body, chain grate, front arch, back arch, light furnace wall, steel frame and insulation layer. The main body is composed of a pot shell, a smoke box, a water wall tube, a downcomer, and lower headers on both sides. The tube plate adopts a fully welded structure. The chain grate adopts light chain ten grate, thickened grate pieces, and independent air supply in sections. This boiler has the following characteristics: 　　● Reasonable air distribution, flexible adjustment, can be adjusted at will according to combustion conditions. 　　● Thicker grate slices, higher strength, long life of the grate slices, and long overhaul period. 　　● The furnace structure designed with a unique coal combustion theory enables the boiler to have a faster combustion speed and an efficient and clean combustion effect, and truly achieve no black smoke emission. 　　● Coal types are widely adaptable, and can be burned with ⅠⅡⅢ bituminous coal and lean coal. 　　● F...

Oil gas fired boilers are mainly divided into four categories according to their working performance: oil and gas boiling water boilers, oil and gas hot water boilers, oil and gas steam boilers, and oil and gas heat transfer oil boilers. Hot water or steam is used as the heat required for consumption or life. Common boilers in life are boiling water boilers and hot water boilers; steam boilers are common boilers in industrial boilers. Industrial boilers are mainly used in petrochemical, textile, rubber, locomotive, industrial and mining enterprises and other industries. Gas Organic Heat Carrier Boiler Gas-fired thermal oil boiler refers to a new type of heat conversion equipment in which the heat carrier is high-temperature heat transfer oil (also called hot coal, heat carrier), so organic heat carrier boilers are also called heat transfer oil boilers. Organic heat carrier furnace heat conduction oil boiler uses coal, heavy oil, light oil, etc. as fuel, and heat conduction oil as the...
