What do you know about the advantages of Class D boilers and the preparation before installation?
Steam generator, also known as small steam boiler, belongs to the category of class D boiler, its requirements are 30L≤ its water volume ≤50L, the pressure is less than 0.8 mpa, that is, 8 kg, from the design and manufacturing need to go through the National inspection Institute to approve, design drawings meet the requirements of the boiler, plate in line with the requirements of the boiler material, its manufacturing process ah according to the requirements of the boiler to manufacture. Only according to the regulations of Boiler Safety Technical Supervision Regulation, D class boiler does not need to be informed of installation and does not carry out installation supervision and inspection.
The main difference between the steam generator class D boiler and other levels of boiler is that it is free from annual inspection, without certificate, without special guard of the furnace worker, and it does not need to carry out internal inspection and external inspection twice A year like A, B, C class boiler. It is simpler and more convenient to use.
The advantages of class D boiler are more significant, there are the following points:
1. Floor area. Steam generator covers a small area, the smaller area is not more than one square.
2. Classification of steam generator. Steam generators are normally differentiated by fuel, and are normally divided into four categories, biomass steam generator, electric steam generator, gas steam generator and fuel steam generator.
3. Model number. The model of the steam generator is selected based on the gas output per hour, and if the factory needs a ton of steam per hour, then the required purchase is a ton of steam generator. Therefore, the type of steam generator has nothing to do with the pressure size, and only the fuel used and the gas output per hour.
4, steam generator has the advantages of fast exhaust speed, automatic operation, no manual operation, so as to be widely used in various major industries.
5, water volume: 30L≤ its water volume ≤50L.
6. Pressure: the higher pressure of conventional steam generator is 7 kg.
7, boiler procedures: steam generator, also known as small steam boiler, because the volume of water is less than 30 liters, so there is no need to go through procedures.
Steam generator installation preparation:
1. Check that pipes, instruments and interfaces should be tight and not loose.
2. If the cable is not damaged or the connector is not loose, check the power cable.
3. Check whether the interface is loose or whether other functions are damaged.
4. Check whether the onsite electrical connections are consistent with those described in the circuit diagram.
5. Organize related personnel to learn this document before and after installation, so that installation and users can be familiar with the related content. Pay attention to clauses with warnings or cautions.
6. To facilitate the observation of water level and pressure, provide sufficient light to the water level observation port and pressure gauge, and introduce lighting when necessary.
