The steam boiler heats water to boiling point through fuel combustion (fuel), generating high-temperature and high-pressure saturated steam as the sterilization medium. Its core sterilization mechanism stems from three major characteristics:
1. Efficient latent heat transfer: When saturated steam condenses, it releases a large amount of latent heat (approximately 2260kJ/kg), which is much higher than the sensible heat transfer efficiency of hot water. It can rapidly raise the temperature of the sterilized substances to the sterilization threshold of 100-135℃.
2. Pressure permeation: A steam pressure of 0.1 to 0.4MPa can force steam molecules to penetrate into the interior of the packaging or the gaps between materials, killing deeply buried microorganisms and heat-resistant spores (such as botulinum bacteria).
3. Microbial destruction mechanism: High temperature causes denaturation of microbial proteins and rupture of cell walls. Combined with the moist environment of steam, commercial sterility or pasteurization goals can be achieved in a short period of time.
To ensure the sterilization effect, the boiler system must strictly control two key indicators: steam dryness ≥95% (to avoid thermal resistance caused by moisture) and non-condensable gas ≤3.5% (to prevent the formation of uneven temperature “cold spots”).

The application of steam boilers in the chemical industry
Steam boilers are indispensable core thermal energy equipment in the chemical industry. They use high-temperature and high-pressure steam as the carrier to support the key processes of the entire production process. They are simple, direct and essential to apply.
In chemical production, the core functions of steam boilers are concentrated in three points: First, they heat equipment such as reaction vessels and polymerization vessels, meeting the precise temperature requirements of chemical reactions such as oxidation and nitrification; Second, it assists in separation processes such as distillation and rectification, purifying the components of materials through heating to ensure product purity. Thirdly, it provides heat tracing for pipelines and storage tanks to prevent high-viscosity materials from solidifying, and at the same time supports processes such as material drying and solution concentration.
Its advantages are well-suited to the demands of the chemical industry: it can flexibly choose fuels such as natural gas and biomass, meeting environmental protection requirements. Steam parameters are stable, avoiding production fluctuations. The load adjustment is flexible and suitable for continuous or batch production.
The advantage of gas steam boiler
With the development of society, steam boilers have also gained the favor of many users. So, how much do you know about gas-fired steam boilers? Now, xinda will explain it to everyone.
Xinda boilers are made of special steel plates for boilers, and the production materials and manufacturing processes are carried out in accordance with high standards. After tests by relevant departments, all indicators can meet the national standards.
The Xinda gas-fired steam boiler has a relatively compact structure, occupies a small area, and is safe and stable to use. It has safety protection devices. It will automatically alarm in case of over-temperature or over-pressure, which can ensure the safe operation of the boiler.
Vertical 1ton steam boiler for paper factory
Now steam boilers are widely used in the paper industry. A steam boiler is usually used to dry the paper.
The customer contacted us through the Aliaba International Station platform and needed a diesel boiler for the paper industry. According to the demand of production, we recommend the use of 1ton boiler. Because space is limited, we recommend a vertical boiler.
Xida steam generator sufficient steam, large amount of steam, high steam purity, while drying, but also maintain a certain humidity, improve the quality of paper drying, a large number of steam drying paper efficiency, steam can be recycled, reduce the production cost of enterprises, but also reduce the paper production over the years of pollution.
What is a hot blast stove
Hot blast stove generates heat energy through the combustion of fuel, and then uses air as a heat transfer medium to transfer heat energy to the air through the heat transfer medium in the furnace, so that its temperature rises and hot air is formed. In this process, the hot blast stove requires fans or fans to send air into the furnace and fully mix the fuel to ensure the smooth combustion process.
Hot blast stoves are widely used in many industries, such as metallurgy, chemical industry, ceramics, glass, energy and environmental protection. In the metallurgical industry, hot blast furnaces are mainly used in ironmaking blast furnaces to heat the blast to the required temperature to improve the benefit and efficiency of the blast furnaces. In the chemical industry, gas mixed air hot blast stove can provide high temperature hot air, provide sufficient heat for chemical reaction; In the ceramic and glass industries, hot blast stoves are used to improve product quality and production efficiency; In the energy industry, hot blast stoves can be used for pulverized coal combustion power generation and waste heat recovery; In the environmental protection industry, hot blast stoves can be used for waste incineration treatment to reduce the emission of harmful substances.
Advantages of a steam generator with a sterilizer
Recently, the American customer purchased a 144kw electric steam generator from us, which was used in conjunction with the sterilization pot, and the effect was good. So let me take you through the relevant knowledge.
- Sterilization effect: The steam generator provides uniform and stable steam, so that the temperature in the sterilization pot is evenly distributed, to ensure that the items in the sterilization pot can achieve good sterilization effect within the specified temperature and time.
- Improve work efficiency: The steam generators have the ability to produce steam quickly, which can make the sterilization pot reach the required working temperature in a short time, shorten the preheating time before sterilization, thus improving the overall work efficiency.
How to choose the right steam generator
1. Steam capacity: The first thing to know is the steam production required. Different amounts of steam are used in different scenarios.
2. Working pressure: Different equipment and processes have different requirements for steam pressure.
3. Equipment size: to consider the equipment installation space area, in order to ensure the smooth installation and operation of the boiler.
4. Safety performance: Safety is crucial to the production of equipment. Choosing a boiler with a safety protection device is also crucial to the safe operation of the equipment and life and property. Xinda boiler adopts multiple protection system, overpressure protection, water shortage protection, high temperature alarm, etc., to ensure the safe operation of the equipment.
