How many degrees can the temperature inside a home heating coal-fired furnace go?

The temperature inside a home heating coal-fired furnace can reach 600-700 degrees.

After the fuel is burned on the grate, the flame passes through the short wall to the combustion chamber, from the combustion chamber through both sides of the wing flue to the front smoke box, and then by the flue pipe bundle to the rear smoke chamber, and then by the induced draft fan extraction through the chimney into the atmosphere, not only to prevent the bottom of the pot shell by the high temperature radiation of the furnace, but also make the high temperature pipe plate inlet flue temperature drop, coupled with complementary backwater pilot, the bottom of the pot cylinder without dead water area, but also can effectively prevent the Tube plate due to overcooling, boiling and scaling and the bottom of the furnace convex bag, flue gas to smoke room can play a role in dust removal, but also reduces the original dust concentration.

The heating surface adopts dense rows of circular disk tubes, the heating surface is arranged sufficiently, which reduces the heat load on the surface of the tubes, and the thermal efficiency is high, and the use is safer.

Fuel adiabatic combustion in the combustion chamber, easier to catch fire, combustion is more adequate, improve the thermal efficiency of the boiler. Medium flow is reasonable, heat transfer oil has low inlet to high outlet, the gas generated in the operation is difficult to retain in the furnace, can be easily excluded from the system.

Extended information

Safety elements:

1, the heating furnace can not be installed in the bedroom or the room directly connected to the bedroom to prevent gas poisoning.

3, heating furnace outlet should be installed at the pressure reducing pipe. Its through diameter should be no less than the pipe diameter.

4, the system needs to be installed in the expansion tank, the height of the tank should be the highest point in the system 250mm or more.

5, water inlet and outlet using live connection, easy maintenance.

6, vertical smoke tube height: coal furnace should be more than two meters, bulk coal furnace must use 120mm diameter smoke tube, should be more than four meters, through the sky smoke tube to add a cap, the best summer smoke tube is not used to remove the horizontal smoke tube should be short, the elbow should be less, the wind should be added to the smoke tube tee.

7, the slope of the dry pipe in the horizontal case should be 100:1, conducive to exhaust.

8, it is strictly prohibited to install valves on the decompression pipe, exhaust pipe, make-up water tank, otherwise it is very dangerous.
