Boiler auxiliary equipment To a certain extent, it refers to the supporting equipment of the boiler, which is a relatively general concept. The auxiliary equipment of electric boilers, oil-fired boilers, gas boilers, and coal-fired boilers are different, and the auxiliary equipment of hot water boilers, hot water boilers, heating boilers, bath boilers, and steam boilers are even more different. In general, boiler auxiliary equipment includes: electric heating tubes (stainless steel electric heating tubes and ceramic electric heating tubes), burners (oil burners and gas burners), boiler water treatment equipment, water pumps, instruments, valves, grates, economizers, blowers, induced draft fans, dust collectors, chimneys, high-efficiency economizers, etc.
Characteristics of boiler auxiliary equipment:
1. Boiler auxiliary equipment It is a stainless steel electric heating tube, with small size and large power. The electric heater mainly uses a bundled tubular heating element, and each bundled tubular electric heating element has a maximum power of 5000KW.
2. Wide range of applications and strong adaptability. This circulating heater can be used in explosion-proof or ordinary occasions. Its explosion-proof grade can reach B and C levels, its pressure resistance can reach 10Mpa, and the cylinder can be installed vertically or horizontally according to user needs.
3. Fully automatic control. Through the heater circuit design, the automatic control of parameters such as outlet temperature, pressure, and flow rate can be easily realized, and it can be connected to a computer to realize human-computer dialogue.
4. Long life and high reliability. The heater is made of special electric heating materials, and the design power load is reasonable. The heater adopts multiple protections, which greatly increases the safety and service life of the heater.
5. The stainless steel electric heating tube uses a metal tube as the outer casing, and the spiral electric heating alloy wire (nickel-chromium, iron-chromium alloy) is evenly distributed along the central axis inside the tube. The gap is filled with compacted magnesium oxide sand with good insulation and heat conduction performance. The two ends of the tube are sealed with silicone or ceramic. This metal-sheathed electric heating element can heat air, metal molds and various liquids. High-temperature resistance wires are evenly distributed in the seamless tube of high-temperature resistant stainless steel. Crystalline magnesium oxide powder with good thermal conductivity and insulation performance is densely filled in the gaps. This structure is not only good, high thermal efficiency, but also uniform heating. When current passes through the high-temperature resistance wire, the heat generated is diffused to the surface of the metal tube through the crystalline magnesium oxide powder, and then transferred to the heated object or air to achieve the purpose of heating.
