Brief introduction of pig house heating boiler

Brief introduction of pig house heating boiler:

With the advent of winter, the insulation of the piggery has become the focus of attention. With the changes in the social environment and related policies, the choice of heating systems in pig houses has also changed.

On   2013 14 month   2013, China deployed 10 air pollution prevention and control measures. One article refers to "comprehensive transformation of heating boilers in small pig houses". The "Air Pollution Prevention Action Plan" that was subsequently issued set specific requirements for 20 tons and 10 tons / hour coal-fired boilers: "By 20 17 years, save , Urban built-up areas above 10 t / h coal-fired boilers are basically eliminated, and new construction is prohibited. The steam volume per hour for coal-fired boilers is less than 20 tons. {3}} tons of coal-fired boilers.

At present, the selection of coal-fired boilers for new pig farms is not easy to obtain approval and is not conducive to the environment. Therefore, more and more pig farms are turning to other heating methods.

It can be seen from the data in the table that coal combustion is still an economical method, followed by liquefied petroleum gas (LPG) and natural gas (natural gas), with less pollution. This is why more and more pig farms choose to heat the boilers in pig houses.

Due to different geographical locations, comprehensive consideration of transportation costs, fixed facility investment and operating costs, comprehensive comparison of specific project options. The relative cost of pipeline natural gas supply projects is low, but more projects use liquefied petroleum gas (LPG) or liquefied natural gas (LNG). Due to the limited capacity of gas cylinders, the gas is frequently inflated, and the operation and maintenance are inconvenient. Some projects use compressed natural gas (CNG) or liquefied natural gas (LNG) on site. Then, the gas station is transported to the building. Compared with liquefied natural gas, investment in natural gas fixed facilities is lower, and natural gas transportation costs are higher. For specific projects, CNG can consult relevant local departments and manufacturers.
