Common specifications and power calculation of electric boiler heating tube
不锈钢电加热管和陶瓷电加热管。 Electric boiler electric heating tubesCommon heating tubes are mainly stainless steel electric heating tubes and ceramic electric heating tubes according to the material .
主要有 不锈钢单头电热管、 304不锈钢电热管 和 双U型电热管三种 常见的参数如下： There are three common parameters of stainless steel electric heating pipe : stainless steel single-head electric heating pipe, 304 stainless steel electric heating pipe and double U-shaped electric heating pipe .
1. The voltage can be designed as: 12-660V, of which 380V is more;
2. Single injection power: 15KW and 30KW;
3. The materials are: 10 # iron, T4 copper, 1Cr18Ni9Ti stainless steel, Ti titanium, etc.
4. Specifications are: U-shaped, W-shaped, special-shaped, electric heating tube with cooling fins, explosion-proof electric heating tube.
Common prices for stainless steel heating pipes are as follows
28.00元 Stainless steel single head electric heating tube 28.00 yuan
36.00元 304 stainless steel electric heating tube 36.00 yuan
Double U-shaped electric heating tube 元 13.00 yuan
发热体 主要有PTC和 mch陶瓷两种， 是由良好的陶瓷作基体，高质量的电热丝串绕而成的，电热转换效率高，升温快、热惯性小，耐高温、耐腐蚀，热化学性能稳定性好，使用寿命长，绝缘强度高，无污染，与其它电加热元件相比可节能30%左右。 The ceramic electric heating tube mainly has two kinds of PTC and mch ceramics according to the heating body . It is made of good ceramics and high-quality electric heating wires. Corrosion resistance, good stability of thermochemical properties, long service life, high insulation strength, no pollution, compared with other electric heating elements, it can save energy by about 30%.
Ceramic electric heating tube features:
1. Has good thermal efficiency and uniform heat generation;
2. High temperature and corrosion resistance;
3． With good safety performance;
4． long lasting.
5． The product is suitable for heating various electric heating boilers.
How to calculate the power of electric heating tube of electric boiler
P-power required by electric heater (KW);
C —— Specific heat of heated medium (Kcal / (kg · ℃)
M-mass of heated medium (Kg); ΔТ-difference between set temperature and initial temperature (° C);
t-time specified from the initial temperature heating medium to the set temperature. (h);
F-heating medium flow, (generally the maximum flow) (m / min);
M increase-increased media quality per hour
