Brand Name: Yuanda Boiler
Model Number: WNS
Place of Origin: Henan, China (Mainland)
China boilers applied combined with building materials machin
A boiler is a closed vessel in which water or other fluid is heated. The heated or vaporized fluid exits the boiler for use in various processes or heating applications. Steam boiler / generator is a device used to create steam by applying heat energy to water, which used wherever a source of steam is required. Oil steam boiler/ generator is burn oil fuels to heat water in boiler drum to generate steam.
Fully welded pressure steel structure
Material, 1. Special steel plate for pressure vessels & boilers
2. Seamless steel tubes
Reverse chamber is in the end of corrugated furnace, which is set in boiler water completely, forming
wet-back structure.
Flame come out of burner and go into corrugated furnace. Central heating parts of boiler.
After coming out of corrugated furnace and reverse chamber, flame and high temperature gas go through short spirally smoke tubes to front smoke box, forming second heating pass, and then through spirally long smoke tubes to back smoke box, forming third
heating pass.
Flame and high temperature gas flow through them forming three heating passes, reinforcing heating, reducing welding stress.
Packed out of boiler proper, insulation layer reduce heat loss
Burner
Brand: Italy Baltur, Riello, German Weihaupt, Finland Oilon, etc.
Function:Ignite gas or oil fuels, two-stage operation (high/low flame). Burner's fan blows boiler furnace first, and then igniter lights fuel to burn.A controller of burner is equipped in electrical cabinet. When pressure reaches setting datas, electrical cabinet send signals to burner. Burner will adjust flame to large or small or stop automatically. When water level of the boiler is lower than the setting data, burner will stop automatically.
Electrical Cabinet
LCD screen, on/off button of burner, water pump, indicator light of auxiliary machines
Functions, showing working condition of boiler and all auxiliary machines. Showing steam pressure, temperature and water level datas. Showing on/off indicator light of boiler, burner, water pumps.Start or shut off boiler, burner, water pump and the whole working system. Automatically control all machines in the whole system work properly and safely based on signals of gauges and controller. When error occurs, shut off all machines automatically, and sound-light alarm.
Water Pump
Vertical stainless steel multistage centrifugal pump
including pump and motor
Generally install two sets, one is on-duty, the other is stand-by.
Functions, pump water into boiler drum in different flow based on water level of boiler drum. ON/off button is set on electrical cabinet. Electrical cabinet control its working according to signals send by water level indicator in boiler drum.
Water Treatment Equipment
Including Ion exchanger, salt tank, bag package resin
Functions, Na+ in the resin exchange Mg+, Ca+ of feed water before it flows into water tank and boiler drum to reduce water hardness, some impurities and algae, sterilization.
Steam Header
Material, special steel plate for pressure vessels & boilers
Functions, after steam come out from boiler, it flows into steam header to various pipes.
Stack
Material, carbon steel
Functions, exhausted gas flow tubes, promote combustion.
Condenser
Material, steel plate, rock wool
Functions, both exhausted gas and feed water flow through it to exchange heat. Hence, lower exhausted gas.
Safety Valve
Function, when boiler steam pressure is higher than its highest safety pressure, safety valve will turn on automatically to release steam protecting the whole system.
Pressure Controller
Function, feel and send boiler steam pressure to electrical cabinet to control burner.
Water Level Sensor
Function, send water level to water level indicator and electrical cabinet. Electrical cabinet control water pump work based on its signal.
Pressure Gauge
Function, show boiler steam pressure.
Electric Contact Pressure Gauge
Function, show boiler steam pressure.
Water Level Indicator
Function, show boiler water level.
