DD202938A1 - HEATING CELL IN SEGMENT CONSTRUCTION FOR MULTIVALENT HEAT SUPPLY - Google Patents

Abstract

The modular boiler room for multivalent heat supply is used in heating technology and district heating for the timely, parameter-related supply of hot and hot water heating systems, steam heating systems and their combination including hot water preparation. The boiler room cell consists of a main segment and a Beistellsegment, the latter being adapted in the equipment of the respective supply task. The main segment contains a steam three-pass boiler with grate firing. The sequence of the segments is easy to assemble, since the cross-sections of the segments are the same in dimensions. The boiler room cell can be converted and the additional segment can be exchanged.

The boiler room in segmental design for the divalent heat supply client in the heating technology and district heating supply usually for limited time, parameterized supply of hot water and hot water heating systems, steam heating systems and their combination including the hot water, The boiler room cell requires only minimal structural engineering for commissioning Expenses and is easy to implement.

Well-known technical solutions

Abroad, a variety of co.ntainerartigen boiler room cells are built (/ 1 / bis / 5 / and / 8 / bis / IC /). These solutions are peculiar to that

- The heating takes place mainly with liquid or gaseous fuels;

- The container-like cells consist of one piece;

- they are prepared for a special use (steam or water heating systems).

In the GDR two Heizraumze Ilen / 5 / and / 7 / are manufactured. They are heated with solid fuels, each in

housed in a container and suitable only for the connection of small hot water heating systems to 90 ⁰ C flow temperature.

Object of the invention

The invention serves the purpose of using solid fuels, preferably crude lignite, in a boiler room cell and to be able to supply a wide range of heating systems of very different parameters with minimal connection preparation. Despite the required multivalent operating conditions, the design should summarize typically recurring components in container-like segments that can be flexibly combined. At the same time, the transport weight should be lowered.

Essence of the invention

The invention is based on the Aufaabe to supply in aer practice occurring diverse heating systems at short notice with heating heat in the form of hot or hot water and low or high pressure steam, with always only solid fuels are used.

This object is achieved by a boiler room cell in segmental design. In the main segment there is a steam three-pass boiler with grate firing and integrated a shell and tube heat exchanger, the coaling plant - preferably with V '/ urfbeschickung -, the SauQzug with connecting piece to be set up next to the main segment chimney, preferably as

Sheet metal chimney formed, the feedwater device SO ₁ WiS the safety devices and safety devices required for the proper operation of a boiler.

In the Beistellsegmenten the facilities for heating-side adaptation to the heat consumer are housed. For example, for the connection of a sliding or constantly operated water heating system consisting of mixing section for Rücklaufbeimischung in the supplied flow water including Temperaturregler- and limiter, static pressure maintenance system, preferably up to 0.7 MPa, circulating pump group, manifold and collector or as a connection system for a downstream steam heating system , consisting of water treatment plant, condensate collection vessel and steam distributor or combined supply, said assemblies are housed in a Beistellsegment.

Main and side segments are built in the style of the known container. They are, as they have the same cross-sections, reihbar. The construction cost is extremely low ·

The subdivision into segments offers the advantage of a continuous prefabrication with high volumes for the main segment, a flexible, the conditions of use adapted linkage and a transport weight reduction, Furthermore, in this solution, despite the use of a heat generator with grate firing the connection of '.

The invention is explained with reference to FIG. 1 It is to fulfill the task of temporarily supplying 190 residential units with heat. The building heating system has the parameters at full load:

110 ° C / 70 ^G C; Q = 1.0 MW; Δρ = 0.06 MPa.

It is a main segment 1 with a steam three-pass boiler 5 (fuel: lignite briquette or lignite coal) used. Its maximum output is 2 t / h steam at 0.3 MPa. In the steam room of the boiler, a heat exchanger is installed, which transfers the maximum heat flow of the boiler Q = 1.2 MW to the water at the given steam pressure and the water-side parameters inlet 70 ⁰ C and outlet 120 ⁰ G. Gas safety valve on the hot water supply is dimensioned for this performance. The pressure in the water system is a maximum of 0.7 MPa.

To the main segment is the Beistellsegment 2 add that contains the mixing section with temperature controller and limiter 10. By mixing return water with a maximum of 70 C into the supply line of 12O "C, the flow for the building heating system can be produced in a quality-appropriate manner.
