Boiler is a kind of thermal energy conversion equipment composed of drum and furnace. It uses fuel combustion to heat water into steam or hot water to provide power for production or help auxiliary production. With the continuous improvement of industrial manufacturing technology, boiler's control has also changed from the traditional full manual operation to the present automatic intelligent control.
An Interlock in the boiler’s control system is a programmed or hardwired condition that forces a device to be in a pre-determined or permissive state before the process can continue.
Depending on design pressure, fuel type, either liquid, gas or solid, all steam boiler require interlocks to sequence the operation and to prevent damage to the boiler. Examples of such devices are High or Low Boiler Drum Water Level, Low Boiler Feed Pump Pressure, High or Low Fuel pressure, High or Low Atomization pressure (oil fired), Proof of Ignition, Proof of Flame, FD and/or ID (solid fuel) Fan Motor Operation or combustion air pressure, Damper or Valve position and High Boiler Steam Pressure as well as O2 and furnace temperature.
What is a large-scale steam boiler? Generally, large-scale steam boilers mainly refer to steam boilers over 75 tons. Large-scale steam boilers can be divided into oil-fired boilers, gas-fired boilers, coal-fired boilers and biomass-fired boilers according to fuel. At present, the number of large-scale steam boilers used in the industry is still relatively large, among which they are used in chemical industry, food industry, industrial and mining enterprises and building materials enterprises.
There are many challenges and demands faced during the food processing, the choice of a steam boiler can make great difference in a company’s production. So, there are some tips for you to choose a steam boiler for a food processing facility.
Industrial food boilers generate steam or hot water to process, cook, or sanitize food products including meat, fruits, and vegetables. Nearly every aspect of our food supply chain to grocery stores and restaurants involves steam or hot water produced by a boiler in one way or another.
Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships. They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.
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...
Combustion is a process which needs constant air supply for its survival, but as we move up the earth i.e. at higher altitudes, things aren’t the same as they used to be at sea level. Due to decreased air density at higher altitude, it will consume the same volume of air but will not consume the same mass of air.
This results in less fuel consumption & less steam generation rate. Due to the reduction of mass flow of gases through tubes of a steam boiler, convective heat transf...
