Steam boilers play a very important role in food factories and are mainly used to meet the demand for steam in the production process. Specifically, the application of steam boilers in food factories includes the following aspects:

1. Heating and steaming
Steam is used to heat food ingredients, such as cooking vegetables, meats, grains, etc. Steam heating is uniform and the temperature control is stable, which can ensure the quality and taste of food.

2. Sterilization and disinfection
Steam is an effective way to kill bacteria and microorganisms. Food packaging, equipment, canned food, etc. can be sterilized in a steam environment to ensure the safety and hygiene of the products.

3. Drying
During the dehydration and drying process of food, steam is used to heat the drying equipment, causing moisture to evaporate from the food and extending its shelf life.

4. Recovery and utilization of steam condensate water
Some food factories recycle the condensate water from steam boilers, purify it and reuse it, thus saving water resources and energy.

5. Power source for equipment drive
Steam can also be used to drive certain mechanical equipment or systems, such as valves, agitators, etc.

Compared with traditional heating equipment, vertical hot water boilers have many outstanding advantages in adapting to hotel operation scenarios. They can simultaneously balance heating stability, guest experience and long-term operation cost control.

Dual demand simultaneous satisfaction ‌ : It can simultaneously cover centralized heating in guest rooms and 24-hour domestic hot water supply, without the need for additional independent hot water equipment. One system can meet the heating needs of all scenarios in the hotel.
‌
Excellent thermal efficiency performance ‌ : The thermal efficiency of the hot water boiler can reach over 95%, saving 30% to 40% energy compared with traditional coal-fired boilers, and can significantly reduce the heating energy consumption expenditure of hotels, which accounts for 25% to 40% of the operating costs.

Long service life and low maintenance cost ‌ : Equipped with water treatment equipment to extend the service life of the boiler, only simple cleaning is required on a daily basis, and there is no need for dedicated boiler on-duty personnel, reducing labor operation and maintenance costs.

Steam boilers are the core heat source equipment in papermaking production, running through the entire process from pulping to finished products.
1. Pulping and cooking: High-temperature steam cooking of wood chip raw materials to separate fibers is the key to pulping.
2. Wood pulp treatment: Provide heat for the pulp washing and bleaching processes to ensure the whiteness and quality of the pulp.
3. Paper sheet drying: Steam is provided to the drying cylinder to evaporate the moisture of the wet paper. Steam consumption accounts for the highest proportion. Unstable steam can cause the paper to wrinkle, break, and produce defective products.
4. Auxiliary production: Provide process hot water and heating for coating. Large factories can be equipped with alkali recovery boilers. While treating waste liquid, steam is produced to recycle energy.
5. Production Assurance: A stable steam supply directly affects production capacity and the quality of finished products. Boiler failure will cause the entire production line to shut down, resulting in the scrapping of raw materials. It is also a key equipment for controlling production costs.
Steam boilers are the core heat source in the papermaking industry, providing steam for the entire process including pulping, bleaching, and paper drying. They directly determine product quality, production capacity, and production costs.

When choosing a suitable hot water boiler, it is necessary to make a comprehensive judgment based on multiple factors such as the usage scenario, heat load demand, fuel type, operating cost, and safety regulations. The editor has compiled the selection steps and core requirements for your reference.
1. Determine the core requirements
Thermal power is the primary basis for selecting a hot water boiler, referring to the amount of heat that needs to be provided within a unit of time, with units of kW (kilowatt) or MW (megawatt).
Civilian scenarios (residential buildings, office buildings, hotels) : Based on empirical estimates, heating in the north requires approximately 80-120 W/㎡, while in the south, it requires about 60-80 W/㎡. Multiply by the total building area and reserve a margin of 10% to 20% at the same time (to deal with extreme weather and heat loss from pipelines).
Industrial scenarios (factories, workshops, large bath centers) : In addition to heating, the heat demand for production processes and hot water supply should also be taken into account. Precise calculations should be made in combination with equipment parameters, water consumption, and water temperature differences. It is recommended that professional engineers do the calculation.

2. Select the fuel type
Boilers of different fuels vary significantly in terms of operating costs, environmental protection requirements, and installation conditions. It is advisable to select the appropriate fuel type based on local actual conditions.

3. The required installation space
Small boilers are suitable for places with limited space. Large coal-fired and biomass boilers need to reserve boiler rooms and fuel storage areas.

4. Maintenance costs
Gas and electric boilers are easy to maintain, requiring only regular inspections of the burners and pipelines. Coal-fired and biomass boilers require regular ash cleaning and grate inspection, resulting in relatively high maintenance costs.

5. The qualifications and certificates of the boilers they possess
Choose a regular brand with a special equipment manufacturing license and relevant certificates (CE,ISO,ASME) to ensure that the products comply with national standards. At the same time, pay attention to the after-sales service of the manufacturer (such as installation guidance and maintenance response speed).

The principle of a steam boiler: The combustion of fuel generates heat, which heats the softened water inside the boiler. The water boils and turns into pressurized steam, which is then sent through pipelines to production and heating equipment for use.
Two core processes:
Combustion heat release: When fuel (such as gas) burns, high-temperature flue gas is produced.
Water turns into steam: Heat is transferred to the water in the pot, and the water vaporizes due to heating, generating high-pressure steam for output.

1. Fuel factor
The higher the calorific value of the fuel, the less moisture it contains and the lower the impurities, the less material is needed. The purchase price and the level of freight directly determine the basic cost of raw materials.
2. Boiler condition
The new boiler is more efficient. Ash and coke accumulation in the furnace, oversized boiler selection, and inappropriate fan ratio can all lead to incomplete fuel combustion, resulting in wasted consumption.
3. Usage Management
Improper operation by workers, scale buildup inside the furnace, severe heat dissipation from steam pipes, and frequent starts and stops of equipment will all increase fuel consumption. If the furnace ash can be sold, it can offset part of the cost.
4. External environment
In winter, when the temperature is low and more fuel is consumed, the market price of biomass raw materials fluctuates, which will also change the overall fuel cost accordingly

The fuel cost of biomass boilers is mainly determined by four parts: the quality and purchase price of the fuel, the efficiency of the boiler itself and the working conditions of the equipment, the level of daily operation and maintenance, as well as external conditions such as temperature and raw material market conditions. High-quality fuel, well-functioning boilers and standardized operation can effectively reduce fuel costs.

Medium-sized dry cleaners (undertaking linen and multiple equipment) : 0.3-0.5 tons per hour.
Large-scale laundry factories (with multiple ironing machine lines) : Gas boilers are preferred, ranging from 0.5t/h to 1t/h or even larger.

The entire production process of dairy products cannot do without high-temperature heat sources. Clean saturated steam is the safest and most mainstream heating medium in dairy factories. Steam boilers are essential core power equipment in dairy factories, running through the entire production process and indispensable. The following is a detailed explanation of their functions and necessity in sequence

Essential for sterilizing milk
Heat and sterilize pasteurized milk, room-temperature milk and yogurt to control food safety and extend the shelf life.

Heating for dairy production
Boiling condensed milk, concentrating fresh milk and making milk powder all require steam heating and drying.

Cleaning and disinfection of equipment pipelines
Clean the milk cans and delivery pipes with hot water and steam every day. To prevent bacterial residue and comply with food hygiene regulations.

Workshop insulation and heating of auxiliary materials
Heating in the workshop during winter and heating for the blending of various dairy ingredients.

Why use steam boilers
The steam temperature is stable, heats up quickly, and provides heating simultaneously at multiple points, which is clean and pollution-free. One boiler can simultaneously supply multiple workstations such as the sterilization line, CIP cleaning, milk powder drying, and storage tank insulation, making it suitable for the synchronous operation of multiple processes in dairy factories.

Most enterprises choose: low-pressure boilers with a capacity of 0.5t/h to 4t/h (0.6 to 1.0MPa) can meet the demands of the vast majority of small and medium-sized dairy factories. Large-scale milk powder factories will use 6 tons per hour or more. If there are requirements for water quality, water treatment devices can be equipped to ensure the cleanliness of the steam.
