The boiler manhole-lids are mounted from the inside of the boiler so that the boiler pressure will help to keep them tight. Hence the manholes have to be elliptical in shape to make it possible to take the lid out from the boiler.
Among the commonly used steam boilers, those under the pressure of 3.825 MPa are called medium pressure steam boilers, and those under the pressure from 9.8 MPa to 13 MPa are called high pressure steam boilers. Different boiler pressures have different requirements for water quality. Generally, medium and low pressure steam boilers need to supplement softened water, and softened alkali-free water, while high pressure boilers need desalted water. The different water qualities require different corresponding treatment equipment.
In recent years, with the continuous development of new energy technology, China's energy utilization mode has changed from a single form in the past to various forms now. As a green fuel energy, natural gas is widely praised by all levels of society and widely developed and used. Therefore, gas-fired boilers have also become popular boiler equipment in contemporary society.
The raw milk shall be processed through a heat treatment before being bottled for drinking, or turned into other dairy products like cheese, butter, ice cream, yogurt, infant formula, milk powder, casein, or whey powder to sterilize.
Typically, this heat treatment for dairy products occurs at a milk processing plant through one of the following processes:
Pasteurization is a process in which packaged and non-packaged foods (such as milk and fruit juice) are treated with mild heat, usua...
A steam generator is a mechanical equipment that uses the heat energy of fuel or other energy resources to heat water into hot water or steam. It belongs to small equipment and is a kind of steam boiler. According to Boiler Safety Technical Inspection Regulations, a boiler whose water volume exceeds 30 litres belongs to pressure container, national special equipment. There is no need of water storage in the internal structure of modular steam generator concurrent pipeline and the water volume is...
Steam and hot water play an integral role at several stages of the textile manufacturing process. Much of the manufacturing process requires the use of steam or hot water produced by industrial boilers, textile engineering, bulk fabric production, garment manufacturing, or other textile processes.
Pre-treatment
There are several steps in this process, and some of them require both steam and hot water that is clean and pure, which requires an efficient steam boiler.
Dyeing

The primary use of steam boiler in tire manufacturing is the vulcanizing process — the curing of the rubber needs steam to provide heat energy. Curing is a process in which chemical or physical action takes place for harder, tougher and more stable linkage.
As we know tires are the most important part of our vehicle because in all the parts of vehicle tires only remain in contact with the earth hence tires carry all the load of vehicle and passengers.
Vulcanization is a p...
On a steam raising boiler there are three clear applications for level monitoring devices:
1) Level control - To ensure that the right amount of water is added to the boiler at the right time.
