Abstract

FIELD: boiler building.

SUBSTANCE: invention relates to boiler building and can be used to improve pyrolysis boilers. The device for the removal of gases from the fuel hopper during fuel loading through the loading rotary door contains a boiler body, a fuel booker, a loading rotary door, a gate valve made of a gate and a saddle and installed between the chimney channel and the fuel bin. The gate valve is installed perpendicular to the door leaf of the loading rotary door, and the gate is fixed to it from the inside and has the ability to rotate along with the door leaf. The chimney channel is formed in the cavity of the fuel bin and replaces the upper part of its volume. The saddle is made under the chimney channel in front of the chimney channel, and the damper is made under the upper groove of the inner side of the door for laying the seal.

EFFECT: creating conditions for the free removal of flue gases and improving the conditions for servicing the sliding gate valve.

Description

The invention relates to boiler building and can be used to improve pyrolysis boilers.

A device is known for venting gases from a fuel hopper, during the loading of fuel through a loading rotary door containing a boiler body, a fuel hopper, a loading rotary door, a sliding gate valve made of a gate valve and a saddle and installed between the chimney channel and the fuel bin, the sliding gate valve is installed perpendicularly door leaf of the loading rotary door, and the gate is fixed to it from the inside and has the ability to rotate along with the door leaf (1)

The technical result is the creation of conditions for the free removal of flue gases and the improvement of service conditions for the sliding gate valve.

The essence of the invention lies in the fact that the chimney channel is formed in the cavity of the fuel bin and replaces the upper part of its volume, the saddle is made under the chimney channel, in front of the chimney channel, and the gate is made under the upper groove of the inner side of the door for laying the sealant. The saddle is made parallel to the chimney channel. On the end surface of the saddle there is a groove for laying the seal. The gate is made under the upper groove of the inner side of the door for laying the seal, parallel to it.

In FIG. 1 shows an axonometric projection of a boiler with a mechanism for venting gases from the fuel hopper, during the period of fuel loading through the loading rotary door.

In FIG. 2 - section of the boiler, top view

In FIG. 3 - side section of the boiler.

In FIG. 4 - callout 1, section of Fig.3. Gate valve in closed position.

The mechanism for the removal of gases from the fuel bin during loading through the loading rotary door consists of the boiler body 1, the fuel hopper 2, the loading rotary door 3, the gate valve 4, the chimney channel 5, the chimney 6. The loading rotary door 3 is made airtight. To create tightness, both in the boiler body 1 there is a comb 7, and in the loading rotary door 3 there is a groove 8, which fit into each other. A sealant 9 is inserted into the groove 8 - an asbestos or silica cord. The gate valve 4 consists of a gate 10 and a saddle 11. The saddle 11 is made under the chimney channel 5, parallel to it and has a groove 12. A 13 asbestos or silica cord is inserted into the groove 12. Gate 10 is rigidly attached to the loading rotary door 3. To prevent the boiler from blowing up when filled with coolant, the boiler has pressure compensators 14.

The mechanism for removing gases from the fuel hopper during the loading of fuel through the loading rotary door operates as follows. To load fuel (wood, coal) into the fuel hopper 2, the loading rotary door 3 is opened. Since the loading rotary door 3 is rigidly connected to the gate 11, the gate 10 is extended.

The gate 10, as well as the loading rotary door 3, perform a rotary movement around the axis of the door 3. As a result of these actions, the gate valve 4 opens and gases exit through it. When the swing door 3 is closed, the slide valve 4 is also closed.

This mechanism makes it possible to prevent the entry of gases into the room when the loading rotary door 3 is opened and will create ease of maintenance.
