Centralized steam supply scheme for industrial parks
Thread Content
A new industrial park is currently under construction, and four companies are set to move in there. These companies are located quite close to each other and all require saturated steam at a pressure of 0.5–0.9 MPa. However, gas pipelines have not yet been installed in this area. Given the park’s strict environmental regulations, what kind of boiler system should be chosen for a centralized steam supply system? Fuel plan? Feel free to give your advice!
Bro, this requires market research – it can’t be explained in just a few words! You need to figure this out: when it comes to fuel, considering environmental protection and **policy requirements, only gas boilers or biomass boilers are an option; is gas available in the industrial park? How much is the gas price? Pipeline gas or LNG? How is the biomass supply? How much is it? How much is the price for selling steam? There are many issues~ In terms of cost-effectiveness, biomass yields higher profits, but it’s complicated to manage; do you have the capability for that? Gas boilers are much simpler; they are easy to operate. In short, they can generate profits – it depends on how you operate them!
Just how strict are the environmental regulations? Is it still possible to use coal? Can the problems related to natural gas be solved? Some organizations currently don’t use pipeline-supplied natural gas; instead, they have it delivered by truck, although this is more costly
For steam at 1.0 MPa, gas boilers can be considered; CNG is used when the amount of steam is small, while LNG is used when the amount is large. If you have a large demand for natural gas, the suppliers of gas equipment can lend it to you.
How much oxygen is required for steam (now, within 5 years)? If environmental protection and cost are taken into full consideration, carbon molecular vaporization combustion technology can solve this problem.
Steam demand: 30 tons per hour per day
A carbon molecular gasification unit can be built next to the existing boiler (a gas boiler can be used if one is to be installed new). The new process can achieve: emissions that meet environmental standards ； Gasification combustion has low costs; its power consumption during operation is more than 30% lower than that of chain combustion furnaces ； Saves over 50% compared to fluidized bed or pulverized coal boilers ； With the same coal quality and processing method, the carbon molecular gasification reaction is fast and complete, resulting in a high carbon conversion rate; moreover, the calorific value of the gas increases by 10% ； The carbon content in the slag is reduced by 10% ； Combustion is carried out with a low excess air coefficient (α close to 1), resulting in zero chemical incomplete combustion and cleaner emissions ； It is possible to prevent the generation of oxygen-related toxic and harmful substances such as SOx and NOx at the source ； What is even more significant is that the vaporization and combustion of carbon molecules saves more than 10% less air compared to burning coal directly, thereby achieving environmental protection (reducing air pollution) and energy savings (reducing electricity consumption) in an efficient manner ； Reduce heat loss from exhaust smoke)
The legendary vaporizer? ? ? ?
By applying this invention, we have developed domestic boilers suitable for various types of coal in our country, and thousands of such units have been installed and put into use across the nation； Industrial gas furnaces with diameters of Φ1.5m–Φ3.6m were also successfully modified, achieving the goal of increasing both the gas production volume and the calorific value of the gas ； The newly developed tens-of-thousands NM3/H molecular furnace has achieved an engineering demonstration of continuous operation for 36 months upon a single start-up. Currently, new technology products are widely used in kilns for heating and sintering in industries such as building materials, metallurgy, machinery, and chemicals. These extensive and long-term practical applications have proven that the carbon molecule vaporization combustion technology is fully suitable for the characteristics of Chinese coal, which is high in ash content and has a high melting point. According to expert evaluation: the comprehensive indicators of this invention are at the international leading level. Successively listed as **energy-saving scientific and technological achievements ； **Best Practical Technologies for Environmental Protection and Project for Promoting Major Energy-Saving Scientific and Technological Achievements of Chinese People Around the World ； Won the China Green Technology Gold Award and the Ministry of Machinery Industry Award for Technical Progress. Shen Hong, a world-renowned scientist, wrote after operating on it: “An excellent creation that can be promoted.” It is evident that the carbon molecule vaporization combustion technology no longer poses any risks.
If the installation of gas pipelines in the industrial park is on the agenda and it will be possible to use them in one or two years, gas boilers can be chosen; an open area can be designated to build a CNG storage station or a small gasification station with LNG storage tanks (Dewar vessels), depending on the gas consumption
