In a boiler, energy from the fuel is transferred to liquid water in order to create steam. Once the water is heated to boiling point, it is vaporized and turned into saturated steam. When saturated steam is heated above boiling point, dry steam is created and all traces of moisture are erased. This is called superheated steam.
Here are some common issues that could cause your industrial boiler to misbehave.
1. Burner Not Functioning Correctly.
If the boiler burner fails or is faulty, then your boiler is not going to be able to generate heat efficiently, or in the worst case not at all . As industrial boilers are in almost constant use they are built to be very robust and last for decades, nevertheless they can still have problems with broken burners from time to time. Burner pumps, heads and nozzles can all cause problems but a swift replacement should limit your down time.
A dryback boiler has a rear wall that is lined with refractory, a wetback boiler has a rear wall that is jacketed by water. Because of this fact, wetback boilers typically boast higher efficiency than dryback boilers as the heat from combustion goes directly into heating water instead of refractory. Wetback boilers are also more forgiving with load changes as the reversal chamber of the boiler is totally submerged in water creating an even heat transfer on the intermediate tube sheet to furnace joint.
Nitrogen Oxides, commonly referred to as NOx, is a family of poisonous gases. These gases are best known for their role in air pollution, leading to occurrences of acid rain, smog, and the deterioration of the ozone layer.In short, NOx is harmful to the atmosphere and the environment and needs to be limited as much as possible.The problem is that NOx is quite common. It's created as a result of fuel burning at high temperatures. Cars, trucks, boats, and other kinds of vehicles emit NOx almost co...
One of the most important accessories you can have for your steam boiler is a water softener, which serves several purposes and plays a crucial role in helping your boiler avoid malfunctions and run more efficiently. Let's go back to the basics and walk through how water softeners are used in steam boilers.
Today's businesses, regardless of industry, can always do more to improve their sustainability and limit the negative impact their actions have on the environment. There are a number of ways to do this, but one of the best is to use a boiler that's designed to limit the emissions of NOx — one of the most harmful greenhouse gases humans emit into the atmosphere. Aside from being good for the environment, a low NOx boiler can also be good for business.
Boilers with low water volumes require a minimum flow requirement to prevent localized boiling and subsequent heat exchanger damage in a low to zero water flow situation. Minimum flow requirement varies by boiler design. Regardless if a boiler itself has a minimum flow requirement, every hydronic heating system needs to be designed to carry the energy being created away from the boiler to avoid high temperature shut down.
The boiler gas consumption calculation need the following parameters: gas calorific value and boiler thermal efficiency.
Theoretically, the gas consumption of boiler = boiler thermal capacity ÷ (calorific value of gas x boiler thermal efficiency )
Take the 1 tph steam boiler as an example:
= 600,000 cal / (8500Kcal * 0.98) =72m3/h, the 1 tph boiler's gas consumption per hour is about 72 cubic meters.
