WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
1. Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
4. Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
May 02, 2020· The Boiler drum level control is used to maintain these conditions. The objective of the control system is to provide steam at a constant pressure, and to do so with a safe minimum cost. The control must provide adequate feed water to exactly compensate for the extracted one as steam and the last one as blowing.
In general, firing control is accomplished with a Plant Master that monitors the pressure of the main steam header and modulates the firing rate (and hence, the steam production rate) of one or more boilers delivering steam to the steam header.
Effective Boiler-Level Control | HPAC Engineerin. This article will discuss problems associated with high- and low-water-level conditions, the effects of steam pressure and load on water level, components of an effective water-level-control system, the importance of maintaining a mass/heat balance, boiler-level-control strategies, and types of level-measurement sensors.
Steam Boiler Water Level Control | The Industrial …: Mead O'brien Electronic steam boiler controls - Spirax Sarco. 2015-9-10 · Electronic steam boiler controls LC2650 and LP20 / PA20 level control system For accurate control of water levels in boilers and tanks select the LP20 / PA20 capacitance probe and LC2650 multi-functional level controller.
These circumstances combine to make it very difficult to monitor and control the boiler water level to any accuracy. What is required is a calm area of water which is representative of the actual boiler water level. With float and probe type level controls, this is achieved in two ways: External chambers. Internal protection tubes.
The first instrument in this control system is the level transmitter, or “LT”. The purpose of this device is to sense the water level in the steam drum and report (“transmit”) that measurement to the controller in the form of a signal. In this case, the type of signal is electronic type DP Level Transmitter.
This is the simplest form of drum level control and used only for small boilers, where the production of steam is less and constant. This consists of a proportional signal(element) coming from the drum level transmitter. This signal is compared to an input setpoint of water level and the difference between these two is a deviation value.

For a boiler to provide an appropriate amount of such steam
Boiler steam drum water level is one of the most important power plant parameters to both measure and control. Control of the proper water level in the boiler is critical for safe operation of the boiler. If the level is too low, boiler tubes will be damaged by overheating. If the
