Boiler houses are a very complex complex consisting of main and auxiliary equipment, the purpose of which is to convert chemical energy into heat. The main structure includes: a frame, stairs, platforms, a steam boiler, sheathing, fittings, fittings. The auxiliary structure includes: fans, pumps, smoke exhausters, a fuel transmission system, an ash collection system, water treatment and dust treatment plants, and others.
DE steam boilers are vertical water-tube units operating mainly on fuel oil or gas, with natural circulation. They are intended to create superheated or saturated steam and are used in boiler rooms of industrial enterprises for heating, water supply and ventilation. These boilers are equipped with two side drums and a fully screened firebox. The steam capacity of such boilers is in the range of 1-25 tons per hour. Typically, the pressure and temperature are 1.4 MPa and 194 ° C, respectively. Indicators can reach pressures of 2.4 MPa and 380 ° C.
A superheater is a device that signals a steam temperature higher than the saturation temperature. It forms a system of coils connected at the saturated steam inlet to the drum, and at the outlet connected to the superheated steam chamber. At the same time, a water ekmizer - heats up or partially evaporates the incoming water into the boiler. Air heater - heats the air using fuel combustion products.
Valve - a device that is designed to adjust the flow rate of gas, water and steam flows by switching on and off. Also includes such units: shut-off, regulating; control, safety and special. Shut-off valves for switching on and off pipeline sections; the regulating one changes the pressure, and the control one determines the level of the substance; safety one to prevent the back movement of gas and liquids, and a special one is used to remove processed products.
