After the cold furnace of oil fired and gas fired boiler is ignited, the speed of temperature rise shall be controlled at 10 ℃/hour, mainly because the viscosity of oil temperature is large when it is cold, and the flow rate in the heating surface pipe of the whole equipment is relatively low. Tianjin Energy saving steam generator The oil film on the pipe wall is thick, so the heat transfer condition is poor when in use. If the heating speed of oil and gas fired boiler is too fast during use, it is easy to make the local oil film temperature too high. The equipment is in the stage of driving away the residual moisture and moisture contained in the heat conduction fluid in the system within the temperature range. small-scale Energy saving steam generator how much In oil and gas fired boiler, when the steam exhaust volume at the vent pipe of the expander is relatively large, there will be water hammer at the bottom of the equipment. In this way, the vibration of the pipeline will accelerate, and when the swing amplitude of the pressure gauge pointer in each part of the equipment is large, the temperature rise will be stopped and the constant temperature state will be maintained.

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. Tianjin Energy saving 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. small-scale Energy saving steam generator how much 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.

Waste heat boilers are widely used in high energy consumption industries. There are two common types of waste heat boilers: one is used to recover the exhaust gas emitted by ordinary boilers, such as fuel fired and gas-fired boilers, biomass fired boilers, etc. The temperature of the exhaust gas from ordinary boilers is about 600 ℃, which is not too high, Therefore, the requirements for waste heat recovery boiler are relatively low. Tianjin Energy saving steam generator The other is industrial waste heat recovery boiler, such as building materials industry, chemical industry, steel making industry, etc. The temperature of waste gas and waste heat in these industries is high, and the recovery and utilization is also very valuable. small-scale Energy saving steam generator how much Henan Yuji Boiler Vessel Manufacturing Co., Ltd., founded in 2005, is located at No. 8, Jizhong Road, Xiaoji Town, Xinxiang County, Henan Province. It is a comprehensive enterprise of boiler and pressure vessel, mainly engaged in the manufacturing of boilers and pressure vessels, with technological innovation as the core, integrating the design, manufacturing, sales, installation, transformation and maintenance of boilers and pressure vessels.

Waste heat boiler is a kind of industrial equipment. Although the equipment is simple to operate, it also needs special attention in practical application. Tianjin Energy saving 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 small-scale Energy saving steam generator how much 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. Tianjin Energy saving 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. small-scale Energy saving steam generator how much 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.

Economical and energy-saving: the new generation of biomass pellet fuel can save 30% - 60% of the operating cost compared with oil, gas and electric heating boilers. Convenient installation: this series of generators do not need to be inspected, and the tedious annual approval procedure can be avoided. Tianjin Energy saving steam generator At the same time, the machine is assembled for modules, and professional installation procedures are not required. 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. small-scale Energy saving steam generator how much 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.
