Steam Boiler Companies In Egypt
The steam boiler is a large container with very hot water that produces steam and continues to boil. And food drinks and others. It is possible renal steam boilers in Egypt through Misr Boilers Company.
In short, it is a device that produces steam through an application Thermal energy on the water; Therefore, steam boiler is considered one of the main parts of the global heating system issued by power generation plants, and most of the time steam boilers are combined with Another developed system for alloying under very high temperature and pressure.
The reason for naming steam boilers is their high capacity to The generation of hot steam, and the boilers consist of valves and attachments and are considered the best because of their great ability to generate steam, and thus any work is done faster, and for your information, you must choose the type of boiler according to your need for it.
Types of steam boilers
Fire tube boiler: They are boilers that require the flame to be inside the pipes and the water to be in the outer space between the pipes, but the design and production of this type of boiler requires a budget. It is very large and takes a lot of time, so it is considered expensive and difficult to produce, and the water used in the fire boiler is a mixture of natural water with condensates of steam, which leads to the accumulation of minerals and clogging of pipes.
Water tube boilers: They are boilers that operate in the event that the flame is outside the pipes in the outer space and around the water inside the pipes, and when we operate it, the burning gases flow around Pipes, which leads to boiling water and producing steam.
This type of boiler needs a large amount of steam in a very short time because of its large capacity to produce tens of thousands of pounds of steam in just one hour. Water tube boilers are distinguished by the use of their tubes in particular. Because it produces steam with setting the time according to our desire by a slight delay between the operation of the steam boiler and the production of steam.
Also, this type needs a lower water level than the rest. Types of steam boilers Therefore, it responds to a change in the level of vapor produced.
Vertical boilers: They are boilers that operate when the water pipe is placed vertically instead of horizontally, and are used in steam-powered machines and vehicles, such as steam locomotives. .
But its big problem is that the mesh area is very small, so it produces steam in a small amount, and its tubes are not long, so the tubes must be kept at the same length to reduce the height, and thus we lose a large amount of heat through The chimney, because it is not able to heat the pipes.
Also, sediment accumulates in the bottom tube plate, which is located above the firebox.
There are other types of steam boilers that differ according to the fuel they use, there are boilers that operate on diesel fuel and boilers that operate on oil and gas, and steam boilers are characterized by the fact that they were manufactured a long time ago and developed over time to be used in many of domains.
Water Tube Boilers
A water tube boiler refers to a type of steam boiler where the tubes are enclosed by the flow of water and hot gases. Unlike fire tube boilers, water tube boilers are capable of achieving high pressures and steam capacities. This is due to the condensed tangential pressure exerted on the tubes, which is referred to as hoop stress.
Components of Water Tube Boiler
The water tube boiler consists of various components including the boiler shell, burner, mud drum or mud ring, furnace, safety valve, strainer, sight glass, feed check valve, steam stop valve, and more.
- Boiler Shell: The boiler shell refers to the external cylindrical part of the pressure vessel.
- Mud Drum: The mud drum is a cylindrical space located at the bottom of the water area where impurities such as mud and sediment are collected.
- Strainer: The strainer is a filtering device that traps solid particles while allowing the fluid to pass through.
- Sight Glass: A glass tube is used in steam boilers to provide a visual indication of the water level.
- Safety Valve: This is a spring-loaded valve that opens when the pressure reaches a certain level, preventing excessive pressure buildup in the boiler.
- Furnace: The furnace is an enclosed space where fuel combustion takes place.
- Feed-Check Valve: High-pressure water flows through this valve, supplying water to the water tube boiler in a controlled manner.
- Steam-Stop Valve: This valve regulates the flow of steam to the external system.
- Burner: The burner is a device that combines air and fuel at a controlled velocity for ignition. It plays a crucial role in the combustion of gas or oil in the boiler.
High-pressure steam boiler
Water-tube boilers typically have higher maximum pressure ratings compared to fire tube boilers, capable of reaching up to 5,000 psig. To withstand the increased stress associated with higher pressure levels, the tubes in water-tube boilers have a smaller diameter. The ability to operate at higher pressures and faster recovery rates are among the factors that make water-tube boilers preferred in applications requiring higher output, such as chemical processing and power generation stations.
Models for every application
As previously mentioned, water tube boilers come in various sizes, ranging from small to large. The smaller models are conveniently packaged as steam boilers, facilitating their transportation and installation by our boiler service team. On the other hand, the larger designs, which are suitable for high-output industries, need to be transported in separate components and assembled at the installation site. This process may take longer due to the complexity of the assembly.
Water-tube boilers are designed to deliver exceptional performance, aligning with the demands of high-output industries. Their efficiency is specifically tailored to meet the requirements of these industries. These boilers are so efficient that they can generate both superheated steam, which is ideal for high-output energy generation applications, and saturated steam, which is well-suited for heating purposes.
Fire tube boilers
Fire tube hot water boiler also known as shell boilers or drum boilers, are often considered a cost-effective option for steam generation, particularly for smaller industrial uses. In this type of boiler,A fire tube boiler generates steam at pressure by heating the water within the tubes through the heat produced by hot gases surrounding them., while water surrounds the shell, resulting in the production of steam. Fire-tube boilers can be identified by the concept of passes, which indicates how many times the flue gas, or combustion gas, passes through the pressure vessel, transferring heat to the water and generating steam.
Compact and flexible
Fire tube boilers have a relatively compact size, making them conveniently available as packaged units for easy transportation and installation at the desired location. Moreover, their compact design facilitates relocation if necessary. Cleaning and maintenance of these boilers are generally straightforward, involving regular and simple cleaning routines, and replacement parts are readily accessible. If you need any support or guidance regarding the maintenance of your fire tube steam boiler, feel free to contact our team of boiler sales experts without delay.
The furnace thickness of a fire tube boiler sets a limit on its pressure rating and maximum output. According to regulations, the maximum furnace thickness should not exceed 22 mm. Consequently, fire tube boilers are more suitable for smaller industrial applications, as their pressure rating and output capacity usually do not meet the requirements of more demanding and high-intensity applications.
Wet and dry back
Fire tube boilers come in two variations: wet back and dry back. Wet back boilers feature water-cooled combustion chambers, which enhance the heat exchange surface and eliminate the necessity for excessive heat protection on the rear outer casing. On the other hand, dry back boilers utilize refractory lining to increase the heat exchange surface.
Steam boiler components
The boiler of the steam boiler consists of three main systems, which are the steam generating system, the water feeding system, and the fuel system:
- Water Feed System: The water feed system in the steam boiler boiler consists of three main components, which are organizing and preparing the water to be converted into steam inside the boiler. This system includes an open feed system and a closed feed system. There are two main sources of feed water, raw water coming from outside the boiler unit and auxiliary water circulating inside the boiler cooling system. Raw water is used in normal operating conditions, while additional water is used in the event of any emergency in the boiler.
- Steam System: The role of the steam systems is to collect the steam produced from the boiler and pump it through the pipes to the different points of use. The steam transfer process through the pipes depends on the steam pressure, which is controlled using steam pressure gauges and valves. Steam systems are used in many applications such as generating thermal energy, running engines, heating buildings and commercial centers, and other uses that require thermal energy.
- Fuel System: The fuel system consists of a set of essential equipment and components that enable the boiler to generate the required heat. This system is one of the main parts of the boiler, and the necessary equipment is completely determined based on the type of fuel used in the boiler.
