JPS5833032A - Stove with forcible heat exchanging section - Google Patents

Abstract

PURPOSE:To enable to use the stove using various different fuels in an interchangeable manner by providing a central space heater using air as a heat medium in a heating unit. CONSTITUTION:Heat generated by combustion in a combustion chamber provided with a burner is introduced into a heat exchanging section, and sent from the opposite direction of a heat discharging route using air as a heat medium with use of a fan. Thus generated heat is subjected to heat exchange by an overall heat transfer across the partition wall of the passage of the heat exchanging section, and thus obtained hot air is used for central space heating. In the case where a burner using coal as a fuel is of a Lumpen type is used, heat generated by the initial cracking combustion is accumulated, and with respect to the generation of soots, the quantity of produced soots is reduced by hot air from the fan.

Description

[Detailed Description of the Invention] This invention relates to a device in which a central heater that uses air as a heat medium is installed in a "fireplace" and can be used interchangeably with different types of fuel.O burner and combustion A fireplace with a structure that either radiates the heat produced by combustion to the outside as little as possible, or, if necessary, can directly radiate heat to heat the room in which the ``new fireplace'' is installed (hereinafter referred to as ``burner''). The above combustion generated heat is exchanged through the heat exchange section (hereinafter referred to as "heat exchanger section") of the "new fireplace" through heat exchange, and the resulting hot air (hereinafter referred to as "
hot air) is used for central heating. .

The upper part of the burner is used as a heat exchange part to create a new fireplace.
You can also connect it with ``Netbunbu''.

In addition to using the ``hot air'' in the usual way, there is also a method in which the heat is first stored in a heat storage material using parts other than the ``heat exchanger'' of the ``new fireplace'' (hereinafter referred to as ``thermal storage''), and then gradually extracted and used.

There are two combustion methods for ``burners'': one method uses variable input as needed without using ``thermal storage,'' and the other uses ``thermal storage'' and burns intermittently with a constant input.

When using heat storage to send air using a fan, it is sent through a duct to the heating area, and a heat sink is attached to the end of the duct, which sends hot air through the hollow inside of the heat sink. At the same time, the heat is radiated from the surface of the heat sink and used for heating (hereinafter referred to as the "heat sink"), but the method of installing a general-purpose fan in the exhaust direction of the "heat sink" is suitable for dormitory use. At the same time, it also has the advantage that heat distribution from the duct can be done easily and accurately.

The combination of "heat storage" (hereinafter referred to as "heat sink with dedicated fan") and "heat sink with dedicated fan" reduces the amount of warm air per unit time when blowing compared to the conventional method of passing hot air through a duct. It has the advantage of requiring only a small amount of water, making the diameter of the duct smaller and reducing noise.

In the case of lumpen-type "burners" that use coal as fuel, combustion is divided into "decomposition combustion" in the early stage and "boiling combustion" in the latter stage, but the heat generated by this "decomposition combustion" is transferred to Assuming that the heat storage material is cast iron and the specific heat is Al), the effective temperature difference is 250 t, the lumpen type "burner" - batch coal is lobed, r decomposition combustion" ratio is 50%, heat storage efficiency is 50%9 Calorific value of stone*111F is 6000 Km
When calculated as 1, cast iron can store heat in 6001y.During coal lumpen-style decomposition combustion, soot is generated.
However, this is mainly due to a lack of primary and secondary air9, and as a solution to this problem, the hot air obtained by the fan is sent to the combustion chamber using the above-mentioned "thermal section" to generate "swath". There are ways to reduce it.

If the temperature of the "warm air" is 185 degrees Celsius (1 atm), the air is approximately a! KaIt/l: Can send the amount of heat of a male.

The constituent materials of the "new fireplace" are: the "heat exchanger" is a metal body, the exterior is made of conventionally used bricks or something similar, and metal bodies, etc., and the floor is constructed and fixed;
) and "new fireplaces" were mass-produced at the factory, and 4
There is a method that requires 11 people to assemble and install.

In addition, the ``new fireplace'' is different from the conventional ``pechika'', in contrast to the ``pechika'', which connects multiple rooms and provides heating from the central part of the house, so to speak. , "New fireplace" can require heat dissipation from the places where cold air enters, such as the room side or the room divider.

Furthermore, it can be easily applied to "floor heating".

The upper part of the fireplace can also be used as a flue and a natural convection heat exchanger.
You can use a conventional central heater that functions as a flue, heat storage, and heat dissipation part (surface) by storing it in this fireplace, or you can install a ``burner'' and incorporate a ``heat exchange part'' and a fan. You can also use damono.
