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. Zhejiang Automatic electric 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 Automatic electric 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.

Stainless steel for pressure vessels and its welding characteristics. The so-called stainless steel refers to the addition of a certain amount of chromium in the steel to keep the steel in a passive state and free from rust. Zhejiang Automatic electric steam generator For this purpose, the chromium content must be more than 12%. In order to improve the passivity of steel, it is often necessary to add nickel, molybdenum and other elements that can passivate steel into stainless steel. Stainless steel is generally referred to as stainless steel and acid resistant steel. Stainless steel companies do not have certain acid resistance, and acid resistant steel generally has a good stainless property. small-scale Automatic electric steam generator how much According to its steel structure, stainless steel can be divided into four categories, namely, austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and austenitic ferritic duplex stainless steel.

You will find that the characteristics of industrial boiler equipment are obvious. When designing industrial boilers, they should be regularly maintained. Vertical boilers have obvious characteristics Zhejiang Automatic electric steam generator The combustion part adopts a double-layer grate combustion chamber, which has fast temperature rise and pressure rise, reasonable overall layout, good heat transfer, sufficient combustion, smoke suppression and dust removal for unburned gas after secondary combustion, and is one of the smaller steam and heating equipment. small-scale Automatic electric steam generator how much The characteristics of the whole industrial boiler are obvious, with high thermal efficiency and sufficient steam. The whole industrial boiler is equipped with excellent safety valve, pressure regulator, low water level and other multiple protection devices, which can effectively ensure the safe operation of the boiler. Moreover, industrial boiler equipment is compact in structure, small in floor area, elegant in shape and bright in color. Therefore, it plays an important role in many large factories and coal mining enterprises.

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. Zhejiang Automatic electric 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 Automatic electric 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.
