pv cycle 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.
Technical advantages 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.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
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.
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.
The Rankine cycle operates in the following steps: 1-2-3 Isobaric Heat Transfer. High pressure liquid enters the boiler from the feed pump (1) and is heated to the saturation temperature (2). Further addition of energy causes evaporation of the liquid until it is fully converted to saturated steam (3).
2008-9-3 · A schematic of the components of a Rankine cycle is shown in Figure 8.11.The cycle is shown on -, -, and -coordinates in Figure 8.12.The processes in the Rankine cycle are as follows: : Cold liquid at initial temperature is pressurized reversibly to a high pressure by a pump. In this process, the volume changes slightly.

2005-8-8 · Ideal Rankine Cycle (a) Schematic representation of an ideal Rankine cycle (b) T-s diagram of an ideal Rankine cycle . Application of the First law of thermodynamics to the control volume (pump, steam generator, turbine and condenser), gives . Work done on pump, per kg of water, W P = h 2-h 1 . Energy added in steam generator, q 1 = h 3-h 2
2015-12-4 · 4.4 ENERGY EFFICIENCY OF SUPERCRITICAL RANKINE CYCLE It may be recalled that, the energy efficiency of the cycle is defined as the ratio of network done to the heat supplied in the boiler of the steam power cycle, From the figure 1.1, Energy efficiency = Wnet / H.S (4.1) Where Wnet = Wturbine - Wpump kJ/kg (4.2)

Steam Boiler | Working principle and Types of Boiler Boiler or more specifically steam boiler is an essential part of thermal power plant. Definition of BoilerSolar Photovoltaic (PV) Systems
Boiler Short Cycling Short Cycling. Boiler short cycling occurs when a boiler subject to its own internal thermostat 'fires up' - starts operating when the thermostat detects that the water in the boiler has cooled down.. For example: When your heating system does not require the boiler to fire, the heated water in the boiler's heat exchanger will begin to Zozene heat to the air around the
2017-1-16 · I - Power Plant Steam Cycle Theory - R.A. Chaplin some form of water treatment in the boiler or prior to the water entering the boiler was required. If however the exhaust steam was condensed and re-used the need for fresh supplies and for water conditioning was substantially reduced.
|2019-5-27 · The Rankine cycle is a model used to predict the performance of steam turbine systems. It was also used to study the performance of reciprocating steam engines. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work while undergoing phase change. It is an idealized cycle in which friction
