Abstract
A new type fuel with lime carbonate as main ingredient and its process for preparing are disclosed. The invention provides a covered granular fuel with lime carbonate as main ingredient and its process for preparing, in which the said lime carbonate contains more than 60 % of lime carbonate and less than 40 % of coal (weight ratio). The fuel is a multifunctional and composite new type fuel which is energy-saving, cleaning, no waste-slag burning and product-calcining.
Description
The invention belongs to synthetic fuel's technical field.
Present synthetic fuel is that the organic or inorganic waste, earth and other chemical industry that add town and country fire, auxiliary material is made with energy-conservation is the single purpose energy-saving fuel, but the burned material of synthetic fuel's user after using burning still produces new waste residue, the commercial value of this waste residue is extremely low or equal zero, so just become waste puzzlement urban and rural environment again because of the market utilization ratio is too low.
The invention provides with the Wingdale at the problems referred to above is that the novel fuel of base-material and making method have just solved this problem well.
The present invention is achieved in that with lime and makes binding agent and add coal dust and water is transferred and to be mixed the coal paste shape with viscosity, is particle diameter 5mm～50mm, optimum grain-diameter is that 10mm～20mm Wingdale small pellets is put into the coal paste stirring, make Wingdale small pellets particle outside cover one deck coal clothing, with artificial or natural mode with the coal clothing on the small pellets particle outside dry or solidify after, formed limestone content is more than 60%, the collection of coal dust content (weight ratio) below 40% is energy-saving, clean, no waste residue burning type, the Wingdale of product calcinated type multifunctional and composite type covers formula small pellets fuel.
The advantage that the present invention possessed has: the burned material after this fuel combustion is product-lime, so constituted the novel fuel that collects multiple function composites such as energy-saving, clean, no waste residue burning type, calcination product type.
Embodiment is described further below in conjunction with indefiniteness: it is 5mm～50mm that enterprise or individual A are broken into the material footpath with common stoning machine with the limestone block material, optimum grain-diameter is that the small pellets of 10mm～20mm is deposited in the material storehouse, with coal pulverizer coal cinder is ground into coal dust, binding agent with lime (best bond agent) work, its ratio is that coal dust is 80%, lime is 20% (weight ratio), add an amount of water again and transfer and mix coal paste shape and pour stirrer into viscosity, again the Wingdale small pellets also being poured into stirrer stirs, make outer the adhesion and covering one deck coal clothing of particle of Wingdale small pellets, then with nature or manual type make the coal clothing of small pellets particle outside dry or solidify after, formed Wingdale contains 70%, coal dust contains the formula that the covers small pellets fuel of 30% (weight ratio), sell to the usefulness that user B makes boiler oil, user C makes the usefulness of the fuel of life heating, user B and C are in use, its incendiary low-temperature zone 300～800 degree are made the usefulness of heating function, its incendiary high temperature section 500～1100 degree are made the usefulness of calcining function, so, Wingdale covers formula small pellets fuel and fires (forging) resultant after burning and do not produce waste residue, produce a kind of product: lime can be used as commodity again and sells to user D, user E etc. makes usefulness or other commercial articles for use of building materials.The heat that Wingdale covers in the coal stone ratio in the formula small pellets is taken into account user's heat demand, and present embodiment coal stone ratio is 30%: 70%; Therefore, to cover the formula small pellets be a kind of multifunctional and composite type novel fuel that integrates energy-saving, clean (sulphur removal is good), no waste residue burning type, calcination product type to Wingdale.
Example 2: sand-lime brick field conventional production process is: make fuel and lime masonry raw material with raw coal, adopt layer to burn formula skill wood lime kilning or outsourcing lime; Make fuel and burning in boiler steam with raw coal; This arts demand secondary raw coal and secondary combustion, the very big labour cost that consumes energy is also high.Now directly adopt Wingdale 75%, coal dust 25% to cover formula small pellets fuel, the input effect that boiler combustion produced is: small pellets fuel high temperature section is at lime kilning, and its low-temperature zone is being produced steam; Though the primary combustion of this fuel but is the cascade utilization form, produce the necessary two kinds of starting material of sand-lime brick field simultaneously: lime and steam, so comprehensively economize on coal reach more than 40%, labour cost reduces more than 25%.Binding agent is with lime the best, because it is the reversible reaction, combustion (forging) still becomes lime after burning.Certainly cement, water glass, clay also can be made binding agent.
Claims (2)
1. the novel fuel and the making method that with the Wingdale are major ingredient is characterized in that: make binding agent and add coal dust and water is transferred and to be mixed the coal paste shape with viscosity with lime, (best 10～20mm) Wingdale small pellets are put into coal paste and are stirred particle diameter 5mm～50mm, make Wingdale small pellets particle outside cover one deck coal clothing, with artificial or natural mode with the coal clothing on the small pellets particle outside dry or solidify after, formed limestone content is more than 60%, the collection of coal dust content (weight ratio) below 40% is energy-saving, clean, no waste residue burning type, the Wingdale of product calcinated type multifunctional and composite type covers formula small pellets fuel.
2, said according to claim 1 is the novel fuel and the making method of major ingredient from Wingdale: it is characterized in that: binding agent also comprises water glass, cement, clay etc.
