Boiler economizers are devices that help to improve the efficiency of industrial boilers by recovering heat from the flue gas and transferring it to the boiler feedwater. In this article, we will explore how boiler economizers work and the benefits they offer. We will also introduce ZOZEN's boiler and economizer solutions that can help improve the energy efficiency of your industrial operations.
How Do Boiler Economizers Work?
A boiler economizer is essentially a heat exchanger that recovers w...
Before the technical communication, there is no way for any manufacturer to give an accurate figure about the price of oil-fired gas-fired steam boiler immediately.
The price of oil-fired steam boiler is mainly affected by the following factors:
1. Technical parameters such as tonnage, pressure, temperature and thermal efficiency
2. Specific system configuration and brand of the boiler
3. Manufacturing process of the boiler
4. The altitude of the area where the boiler is used
5. Freight, s...
The boiler water level gauge is a detection instrument that shows the water level of the boiler, and it is one of the important safety accessories of the steam boiler.
Boiler parameters are the main indicators of boiler performance, including boiler capacity, steam pressure, steam temperature, feed water temperature, etc. Boiler capacity can be expressed by rated evaporation or maximum continuous evaporation. Rated evaporation is the amount of steam continuously produced per unit time under the specified outlet pressure, temperature and efficiency. The maximum continuous evaporation is the maximum amount of steam that can be continuously produced per unit time under the specified outlet pressure and temperature.
Boiler steam pressure control refers to maintaining the steam pressure of boiler drum by adjusting the fuel control system. Its basic task is to adapt the heat provided by fuel combustion to the steam load of boiler drum. At the same time, it is necessary to ensure the safe and economic operation of boiler drum and meet the requirements of environmental protection.
Generally, small gas-fired hot water boilers are between 0.7 MW and 14 MW, and the output of boilers is different, so the prices are different. Different pressures require different techniques, materials and pressures. The higher the pressure, the higher the price.
The type and parameters of coal-fired boilers are the direct factors affecting the cost of a small coal-fired boiler. For example, rated capacity, rated steam pressure, rated steam temperature, feed water temperature, etc. With different parameters, the more requirements, the higher the price.
A water level sensor fail on a steam boiler is extremely dangerous. The low water cut of should be tested daily. If the sensor fails the boiler could turn all the water into steam, leaving the boiler dry. Without water in the boiler the flame from the burner would heat up the heating surface to extreme temperatures and would crack and damage the inside of the boiler. But that’s not the dangerous part. If water added to boiler while it is extremely hot. Once water touches the extremely hot heating service, water would immediately start to evaporate into steam. When water evaporates it expands 18x it’s original size. The boiler would explode from the sudden increase in pressure from the inside. Some in some cases, boilers that have exploded out of a building and have landed 100s of feet away.
