The cast iron block economizer EB2-236 is a tubular heat exchanger in which the feed water is heated before entering the boiler to a temperature of 30 - 40 ° C below the boiling point in order to prevent vaporization and hydraulic shocks inside it. Heating occurs due to the heat of the exhaust gases, thereby increasing the efficiency of the boiler unit. Economizers consist of bundles of finned pipes, interconnected and enclosed in a frame with a heat-insulating sheathing. Completed (at the request of the customer) with a box for gas supply. The movement of feed water in pipes that make up a common heating surface is towards the flow of flue gases. The use of cast iron in heating surfaces and fittings significantly increases the service life compared to steel economizers. The use of steam (P) or gas-impulse (I) cleaning will allow you to constantly have clean heating surfaces, which means that you save fuel with minimal maintenance and the complete elimination of manual labor. By agreement with the Customer, the economizer can be equipped with a device for cleaning heating surfaces GUV (shock wave generator). Supplied assembled, one transportable unit. The installation of the economizer is reduced to its installation on the foundation, the manufacture and installation of a supply gas duct with explosive safety valves, and its connection to the boiler feed pipelines. Installation of the cleaning system - in accordance with the boiler room project and passport. To ensure gas tightness, sheet or corded asbestos should be laid between the economizer and the foundation. Fastening to the foundation is carried out by welding the lower frame of the economizer to the embedded elements. The upper gas duct is welded to the economizer with a continuous seam. In two-column EB economizers, the economizer and gas duct partitions must be welded together. After completion of installation, subject the economizer to a hydraulic test. They are installed individually on a boiler or on a group of boilers of low pressure (up to 2.4 MPa) and low power and can be disconnected from the boilers both through the gas and water paths.

The PTB-1200 drive is used to drive the grate of mechanical furnaces TLZm, TChZm. Alternative name - PTB-1200 reducer. It has a stepless regulation of the rotation speed by changing the speed of the electric motor. The PTB-1200 drive is used to drive the grate of the furnace, which has a stepless control of the speed of rotation by changing the speed of the DC motor. The drive consists of: - worm gear, - gear boxes, - outer pair of gear wheels, - couplings, - frames. The worm gearbox is assembled in a cast iron housing. The worm wheel is mounted on a shaft that rotates on sleeve bearings. Axial loads are absorbed by the end face of the right or left hub, depending on the direction of the wheel movement. The axial position of the worm wheel is adjusted by rings installed between the wheel and the hub. The worm shaft is mounted on rolling bearings. Axial loads are supported by a thrust bearing. The outer pair is straight-toothed, installed in a special cast-iron casing. The gear wheel of the outer pair on the worm shaft is installed freely, and the torque is transmitted through the toothed discs of the safety clutch. The toothed discs are pinned to the toothed wheel and the coupling half. The overload clutch is adjusted to transmit a certain torque, depending on the size of the furnace. If the safety clutch fails, the pins holding the toothed discs can shear off. PTB-1200 drive gearboxes do not have gear shifting.
