Whether the water quality in the gas-fired boiler reaches the required standards is directly related to the safety, performance and service life of boiler. The water must be treated before the boiler operation. However, what are the water quality standards for the gas-fired boiler?
When using the thermal oil heater, users often add some auxiliary device to the boiler for more stable and safe operation. This is an introduction about the installation and using tips of thermal oil heater's auxiliary device.
Before the operation of oil-fired boiler, we should effectively adjust the heating system to make it conform to the actual working conditions. Moreover, what are the specific operating steps when adjusting the oil-fired boiler?
As a kind of essential equipment applied by many enterprises, condensing boiler is widely favored and recommended for its advanced condensation heat transfer technology, intelligent operation mode and high efficiency in the production. Let us talk about the main significances of using condensing boiler from the following three perspectives.
The fuel of coal-fired boiler will release some harmful substances after combustion that are harmful to human body, but also pollute the environment. Therefore, the desulfurization treatment is required for coal-fired boiler, including desulfurization before combustion, desulfurization during combustion and desulfurization after combustion. The specific operating methods are different.
The explosion-proof door of the gas-fired boiler is opened or broken when the combustible gas explosion suddenly increases the pressure, it then releases high-pressure gas to reduce the damage to the gas-fired boiler body and also ensure
The function of the gas-fired boiler explosion-proof door is usually reflected when the gas-fired boiler is ignited or running due to improper operation. For instance, the furnace is not purged before ignition, the furnace is still not purged even the ignition cannot successfully be lit, the nozzle is leaking, the fuel is not completely burned, and extinguished failure to cut off fuel quickly, etc. all of them may cause the furnace and tail flue to explode. Installing explosion-proof door for gas-fired boiler is to release the pressure to avoid the accident from expanding and also to ensure the safety of the industrial steam boiler when a slight explosion occurs in the furnace or flue.
Regular inspections can identify and correct faults in the safety systems that are designed to prevent accidents.
When it comes to regular maintenance, the cost of the inspections and repairs will be dramatically lower than the loss of time and profit from a broken boiler that requires replacing. Don’t let maintenance fall by the wayside. Schedule it at even intervals throughout the year.
It could also say, how much heat is required to rais the water temperature from 60 ℃ to 90 ℃.
To calculate heat required follow below steps
Q= mCp dt
Where
m - water flow rate (kg/hr)
Cp- specific heat of water
dt- temperature differences ( 90–60)
You will get heat required in kcal/ hr.
dividing to Q by fuel GCV and system efficiency you will come to know how much fuel (either it is coal or oil) required to raise the temperature of water from 60 ℃ to 90℃.
