Natural draught, log burning boiler - (Coppers) on coal a tree. The market review on coal a tree boiler. How to make a choice to the consumer?
In the Russian market of heating, in a segment on coal a tree coppers, many manufacturers offering various models and updating are presented. The given review represents practically all palettes today and is aimed at the help to the consumer in a choice on coal a tree a "copper".
If for you the main gas - foggy prospect, and present cost of diesel fuel (95 gasoline’s practically made even to the price) - unreasonable expenses (a copper after all not luxury, and heating means), and an electricity - energy expensive, moreover and a variable (that it is it have disconnected) exit one - as energy source for heating to use firm fuel - fire wood, wood, brown or coal, anthracite, coke, pellets, peat briquettes.
To use of firm fuel as energy for heating are applied on coal a tree boiler.
The help information on cost of various kinds of fuel (gas, coal, a diesel engine, an electricity, fire wood, pellets and so forth), coppers of heating used at operation, look in the end of a material.
So, if other alternative is not present, we choose on coal a tree a boiler.
At once it is necessary to note some the important moments for the consumer.
The FIRST - coppers from the point of view of thermal energy reception share on "classical" and (). Well if with traditional "classical" coppers the situation is clear, burns down firm fuel - water (heat-carrier) heats up - the heat-carrier by means of heating devices (radiators, convector’s) gives heat to premises in a case High grade wood gasification boiler coppers in a stage «burns down firm fuel - water (heat-carrier)» heats up there are a little bit other processes.
The principle is put in a work basis Paralysis a copper Paralysis burning (or dry distillation) fuel. The essence consists here in what. Under the influence of a heat and in the conditions of a lack of oxygen the seasoned wood decays on a flying part - so-called High grade wood gasification boiler gas and the firm rest - charcoal (coke). Wood High grade wood gasification boiler is carried out at temperature 200 - 800°С. This this process экзотермический, that is going with heat allocation at the expense of what, by the way, improves having warmed up and fuel in a copper, and occurs heating of burning of air arriving in a zone. Mixture of oxygen of air with allocated High grade wood gasification boiler gas at a heat causes process of burning of the last which is used further for thermal energy reception. Pyrolysis coppers are recommended to be heated as more as possible a seasoned wood then copper work on the maximum capacity and long term of its service is provided.
The difference for the consumer consists here in what. In case of operation traditional "classical" a copper loading of firm fuel occurs time at three-four o'clock, in case of use High grade wood gasification boiler a copper, time between loadings, in difference from "classics" increases in 2 times and more. It is necessary to notice, that Pyrolysis gas in the course of combustion co-operates with active carbon therefore smoke gases on an exit from a copper practically do not contain harmful impurity, being, generally, a mix of carbonic gas and water steam. СО2 such copper will throw out in atmosphere to 3 times less, than usual wood and, especially a copper working on coal. Hence Pyrolysis coppers are more harmless. Also in process High grade wood gasification boiler burning the soot and ashes minimum quantity, therefore a copper is formed is more rare, than usual, requires cleaning.
Let's notice, that High grade wood gasification boiler stand more expensively classical.
Time we have mentioned the important question for the consumer about «manual giving» or periodicity of loading of fuel (that is one of inconveniences at operation coppers), it is necessary to note, as it can be avoided, by means of coppers working on pellets. We will tell in brief an essence. In such coppers giving of granules (pellets) is carried out automatically: pellets from capacity (bunker) with the help шнека move in special pellets a torch. It is necessary for you to fill only periodically the bunker pellets. Agree it more conveniently.
The note: pellets (pellets wood fuel granules) represent the pressed waste of wood manufacture made without application of any chemical additives, as provides ecological cleanliness of fuel. The sizes of wood granules make 6-8 mm in diameter and 5-70 mm long, depending on used raw materials and quality of manufacture). Are on sale in convenient for transportation and warehousing packings.
The SECOND - not all models coppers "are omnivorous", i.e. some manufacturers have models of coppers with the ordered (basic) and reserve kind of firm fuel: for example the basic fuel - fire wood, reserve - brown coal, briquettes, coke or the ordered fuel - brown coal, reserve - briquettes, coal, coke, a tree. For the consumer ignorance of this moment, and a permanent job of a copper instead of the basic fuel on reserve, can be expressed in copper decrease in EFFICIENCY (its thermal capacity) and as consequence - premises. At a choice of a copper and availability/cost to you of this or that fuel - pay to this distinction attention.
The THIRD - heat exchangers at coppers can be steel or pig-iron.
The heat exchanger from pig-iron long heats up and slowly cools down, since pig-iron possesses a high thermal capacity. Pig-iron heat exchangers are more durable rather than the steel. During too time at operation of pig-iron heat exchangers as pig-iron is a fragile material, there is a problem of "a temperature shock» (thermo blow). The considerable difference of temperatures нагретой waters (a submitting line) and leads to "a temperature shock», and to destruction of section of the heat exchanger, excessive cooling by return water promotes formation on an internal surface of the heat exchanger of chemically aggressive condensate. Therefore manufacturers of pig-iron coppers in device characteristics sheet specify the minimum temperature of water in a return highway and measures on its increase. Pay to this attention at operation! Some firms apply design decisions which exclude temperature differences dangerous to pig-iron in the heat exchanger.
Coppers with steel heat exchangers, unlike pig-iron, are more tolerant to temperature differences. Such coppers are cheaper. Worse than pig-iron they that burn through faster, are subject to corrosion which provokes a condensate formed at fall of temperature in a copper below a dew-point. Service life of the steel heat exchanger depends on quality of a steel, its thickness, operation conditions.
The FOURTH. If all the same you soon have a main gas. In this case, not to trifle money, having bought for a current situation Natural draught, log burning boiler the copper, and then under long-awaited blue fuel - gas, for the consumer is an exit. In a ruler of many manufacturers’ coppers there are combined models which work on firm fuel, and then by installation in an existing copper only a corresponding torch (not changing the copper) can work on gas or solar oil. It is convenient and in the future since in a case when you have translated a copper on gas and there is a failure (for example, on a gas highway), you can translate a copper on an operating mode with firm fuel.
The overwhelming majority coppers of foreign manufacturers, from presented in our market, are issued so to say in a household variant, with the maximum capacity to 45-50 kW.
However to cost to notice, that such indicators of the maximum capacity coppers, compelled potential consumers of immense our country (numerous regional industrial companies) at possibility and desire to use firm fuel for heating, to search for other ways of an exit from a situation. Recently, with the beginning of deliveries to the Russian market Austrian твердотопливных coppers Wirbel (Austria) average and big capacity (to 380 kw), existing дисбаланс between a supply and demand it will be eliminated.
Having described, in our opinion, the basic important points at the approach to a choice a copper, we will pass directly to the review import the heating technics presented in the Russian market.
The review coppers, we structured in the form convenient for consumers. In our opinion such form will be most clear and will serve as the navigator at selection coppers.

Coppers are designed in such a manner that with left or on the right side of a copper which operates as the heat exchanger, Swedish torch ATMOS IWABO, which by means of loading шнека a beret pellet the bunker is built in. The bunker for fuel takes places near to a copper and whether in the next premise and can be any size (as a rule, 250 or 500). In case of command reception, i.e. if necessary to heat, the conveyor fills p in a nozzle of a torch and by means of a spiral накаливания there is their firing. When pellet enough inflame, the torch itself will choose the set capacity on which remains until all system will not be heated. Then the torch will be disconnected and pellet, the torches which have remained in a nozzle, will burn down. All cycle, in case of need, repeats. Productivity of a copper and the further work of a torch cope with the help of electronic adjustment which allows adapting copper work to concrete conditions of all system. The big advantage of coppers for pellet is also that in case of need it is possible to remove a torch, to replace with its cover and to heat wood. Thanks to it coppers are convenient as from the point of view of service, and useful properties as at heating by natural gas, prosier-butane or easy fuel oils.

In the present review the market review on heating systems in Russia for private houses in the present text is given - some inexact formulations of terms are possible so for example in Russia following designations operate:
Твердотопливные котлы – Natural wood-gasification-pellet boiler
Твердотопливный котел - Natural draught, log burning boiler
Пиролизный котел - High grade wood gasification boiler
Пеллетный котел - Pellet boiler
The literal translation of a word "котел" c Russian on English language “cooper” - though actually is a question about boiler (boiler’s)
