Definitions

  • the words Renewable, Sustainable and Green are the key words for a 100 % environmentalist MDF product and its production techniques and they are substituting to each other.
  • Cogeneration-w energy generation system is containing a different patent application which has been applied to your organisation by the file number 2016/07119-14937.
  • crumbled wood pieces are converted to fibers by cutting them as thin layers in the grinder, fibers are steamed,
  • MDF boards are constituted by four main components which are wood, resin, energy and technological value added.
  • MDF/HDF wood-based boards Medium/High Density Fiber Board
  • these kind of raw material sources to which the fiber is obtained do not cause to any negative effect regarding the sustainability of the forestry.
  • Unlikely gaining of qualification of a forest depends on its continous rehabilitation. This is possible only with the planned pruning on the tree body and the dilution method of more than one coppices trying to grow from the same root in the way of being shoot forth.
  • the woody structures provided with fibers are the materials in the form of wood branch which is unqualified, fast renewable and at low value, hence what is reqired to remove regularly from the forest region.
  • the removal of these materials from the forest is a vitial process which renders possible to enable the tree main body to be qualified and the forest to be preservable against fire hazard and inspect pests etc.
  • the sufficient and qualified log supply to meet the demand of the carpentry and wood processing industry is possible only by pruning the planted trees regularly according to a good planning. Trees that are pruned regularly grow up not only at an accelerated speed, but also comprising of a lot of number of branches accordingly. As a result of this planned pruning process the volume of this renewable raw material source grows up at geometrical progression and it becomes abundant and so more abundant gradually. So this will result in one hand uninterrupted and sustainable supply of this kind of wood material, on the other hand the cost price to turn to bearish prospect in the market.
  • MDF/HDF Industrial wood-based boards that we know under the abbreviations MDF/HDF are produced when the fibers obtained from wood branch species etc. are pressed to each other under high pressure.
  • Different types of resins are available with diverse structural properties which are activated under pressure and temperature and ensuring the adhesion of the fibers to each other.
  • the conventional resins with fomaldehyde basis are the most common used group although these cause to emissions.
  • the emission is an uninterrupted process continuing in the wood-based board along the chemical life of the resin . The same is valid even for the resins proper to the EO standard with the lowest emission group, according to the European Norm ranking from the highest emission value to the lowest with E2, El and EO respectively.
  • Protein-based adhesives obtained from soya bean and slaughterhouse wastes like blood and bones
  • the most widely used formaldehyde component resins in the MDF production are processed at the highest curing temperature range compared to the other resin types as mentioned above.
  • This highest level curing temperature means the acceptance of the superfluous heat energy consumption.
  • the completion of the curing of the formaldehyde-based resin is realised after the moisture in the pressed material is converted to steam and leaves the medium completely.
  • the reaction process which is continuing along the curing process is not experienced as the same for all resins .
  • the speed and type of the chemical reaction is related to the moisture content in the material and it also depends on the degree of any chemical connection between the resin and moisture .
  • the relation created between resin and moisture is reducing the standard moisture content which should be removed from the medium by evaporation.
  • the main reason of the preference of urea formaldehyde resin in the MDF board production is its low cost advantage. For the sake of this cost saving the operators are granting the consumption of high heat and time in the press. Regardless of the effects on the environment and health, at the cost of consumption of superfluous heat, the preference of the urea formaldehyde resin in order to utilize to the relative low cost advantage can be simply appeared as a right commercial trend in its integrity, but alternately when a no formaldehyde added resin centered functional equation structure can be defined which is comparable with this simple equation the green MDF production theory is gaining a concrete meaning within the commercial/economic frame by its increased applicability in practice.
  • This functional equation is expressed by a formula where four different variables, using the excess heat which is left from the press process to generate renewable power by CHP-w procedure, the excess cost of no formaldehyde added resin, the heat saving in the press and the production gain per unit time, can be solved together.
  • Biomass is the cleanest fuel known. Its waste gas is called as " Gold Powder". Biomass is dryed to use its total heat potential and so the heat value (HV) of the dried biomass is increased considerably compared to its equivalent with moisture. In parallel to its increased HV the carbon emission and ash values are lowered almost to the zero level. Plants are accumulating carbon through photosynthesis during their life. This accumulated carbon is released to the atmosphere by burning biomass. For this reason the carbon emission generated by biomass burning is neglected due to its natural cyclical effect.
  • the main part of the clean and renewable biomass fuel is obtained during the fiber production through the processing of wooden forest materials used as main raw material of the MDF. The remaining part is provided with sanding waste and side cutting powder. Standard sized wood pieces are dried to the required moisture level and then these are adhered together by pressing them under high pressure in natural way. The new structure after this conversion is a new fuel composition called pellet. According to the type of boiler choice wood pellet can be also used as fuel.
  • the moisture level of the fuel and the type of the drying are two important factors to determine the calorific value.
  • one of the most important factors which is reducing the combustion efficiency is high moisture level.
  • the heat value of the fuel reveals to increasing or decreasing linearly depending on its moisture content. Nevertheless , we can not avoid another important issue , if we intend to liberate the full heating value contained in the fuel.
  • the conventional MDF plants are producing only the heat and steam required for their own production processes in their boiler-energy centers. They realise it using their own biomass process wastes. These wastes are burned in the boiler without any classification according to their structural type and size and even without any drying process, whereas most of these biomass wastes are obtained from MDF processes like these are grinded specially for burning in the boiler. If these well prepared biomass wastes could be fired after certain rehabilitation processes , we can see a very distinguished fuel combustion efficiency diagram. In the light of this efficiency diagram nearly the all power required for the MDF production can be generated independent from the grid, if the closed cycle thermodynamic system Cogeneration-w method and closed and semi closed energy management systems giving it functionality are applied together instead of the conventional energy generation and production systems applied in the existing M DF plants.
  • the M DF plant becomes the ability to meet its own heat and steam demand and the power demand by using its own biomass wastes only. So the plant has the chance to generate its own power demand at zero cost using a renewable source instead of consuming the power from unknown sources which has an unclear environmental impact level.
  • a M DF plant can use the wood forest goods (wood branch) to produce its products at an industrial scale and in addition it contributes to the cyclic sustainability and unity of the natural, economic and social life by using the process wastes for renewable power generation.
  • the most important contribution to the formation of the life cycle is taking placing not to interfere to the cyclical functioning and natural balance which has been founded over the billions years by the natural life itself, for the sake of meeting the demand of the social life...
  • the industrial production model which is supporting the unity and sustainability of the life cycle, using a raw material with % 100 renewable and recyclable character under natural conditions, producing the power and energy demand of the whole system by the wastes of this raw material can realise exactly this, when it is also supported intented for the same aim by other limited and comprehensive components like all other auxiliary supply, material and equipment besides the proper technology and so tecnique used in the production process.
  • an industrial production model has been identified with the intention of the society to limit the interference to the natural life cycle or the call "reduce your carbon footprint" which is accepted as the measuring mechanism for this limitation.
  • the renewable M DF production technique is developed as the result of the adaptation of the industrial production model as we determined framework here to the MDF production processes.
  • Heat transfer in a MDF plant is realised using a fluid material called oil which is a petroleum derivative .
  • Oil which is a petroleum derivative .
  • Heat required to generate steam and to heat the surface of the press is obtained through the enthalpy of the hot oil.
  • the hot oil used for heat transfer is deteriorated in time due to the problems related to exposure to high temperature, wear and low circulation speed.
  • the reduced fluidity of this oil will cause irreparable damages in the piping system, if the operation continues. That's why the used oil must be altered to new one in certain time intervals.
  • With the capacity of production line comparatively what is essential to be altered to big amount of petroleum derivative this used oil, whatever the decision is made to bring it to use again, or to dispose it as waste, in both cases it should be converted first using a series of chemical processes.
  • Cogeneration-w system can utilize its excess steam in the hand as an alternative fluid to the conventional hot oil system in order to realise the heat transfer and transport.
  • the only thing to do at this point is to decide to substitute steam to hot oil and to design the new structure and project accordingly.
  • steam is going to be assigned as working fluid to transport heat to the press, to heat the primary air circuit of the boiler, to process the resin, to heat up the boiler feedwater to 104° C and to supply the heat required for fuel and fiber drying.
  • this method which we are expressing as reversible cogeneration or obversely cogeneration is functioning as a closed cycle thermodynamic concept where it uses to the full inner heat content in the boiler except for the unavoidable flue gas discharge in order to generate power first and the energy demanded in the production line is supplied at the required level as an extraction from the turbine in form of steam or liquid fluid.
  • the controlling of the total system efficiency is at the energy production side ensured by closed circuit thermodynamic concept of CHP-w which gives priority to the power generation, at the consumption side as well by favour of the energy operating system which enables to the CHP-w functional.
  • the feature of this operating system is its treatment to energy in gradual , alternate and cyclical mode within closed and semi-closed circuits .
  • This stringent audit mechanism which is a spontaneous result of the systematic character of CHP-w increases to the power capacity up to the maximum possible level.
  • the expression " reduce your carbon footprint” which became the symbol to pollute the nature at minimum rate without limiting the activities of the society has succeeded to reach an ever increasing number of people in the recent years while the global warming problem that is developing on account of the wasteful consumption of fossil fuels is becoming the black trouble of the world.
  • this rate is presenting to a small share in the world population and coming forward as a feature which belongs to the societies at high development level where conscious consumers are living.
  • Cogen-w method has the motivation to create such a commercial stimulation due to its structure increasing the power capacity importantly.
  • This commercial stimulation triggered by CHP-w pushes the company to own a total energy efficiency monitoring and evaluation of policy to earn more revenue generating power.
