Hot water boiler Specifications Model: hot water boiler is one of the important energy equipment production and people's lives can not be separated, it is possible to provide heating, hot water and other purposes. Depending on the fuel, the operating environment can be divided into various types, and each type has a large range of optional capacity.
Boiler plant equipment as three major important energy conversion device, fuel chemical energy into heat energy, and the pot was heated using thermal energy to become hot water having a sufficient quantity and a mass (steam temperature, steam pressure) steam turbine for use. The Anyang City, the power company to my company to buy a split 2 tons of steam condensing gas steam boiler types and capacity for supplying electricity demand. The WNS series split condensing boilers using advanced technology designed to greatly improve the thermal efficiency of the boiler, up to about 96%.
During low nitrogen pressure inside the boiler rises, the need to go through several different stages, and the pressure is increased by certain units, the increase rate of the working medium corresponding saturation temperature is not the same, and the lower the pressure, the height of the unit pressure corresponding saturation temperature rise rate and the greater as the pressure increased, increase in the saturation temperature of the water will become increasingly smaller. Therefore, the national professional boiler manufacturers introduced low-nitrogen booster is very slow at the beginning of time, but wait until the situation under relatively high pressure can be suitably adjusted to improve the speed boost, because elevated pressure and elevated temperature has influence each other , it is not possible to separate transfers, must be considered to operate.
Gas-fired boiler feed pump selection method! Water pump is the main equipment of gas-fired boiler, which is mainly used to replenish water of boiler to meet the normal water demand of boiler. The type selection of water pump mainly determines its flow rate and head. The specific introduction is as follows: 1, the flow calculation of feed pump: Q = k (Q1Q2): the flow rate of Q-boiler feed pump, m3 / h; Q1-Total water supply at maximum steam load for boilers, m3 / h; Q2-other water consumption, such as continuous discharge, periodic discharge and thermostat, m3 / h; k-standby factor 1. 1 ~ 1. 2.2, calculation of feed pump head of gas-fired boiler: h = H _ 1 H _ 2H _ 3H _ 4: h-boiler feed pump head, m; H _ 1-boiler opening pressure of safety valve under designed pressure, MPa; Resistance of H _ 2-economizer and water supply pipeline system, MPa; H _ 3-difference between the highest and lowest water levels of the water supply system, MPa; H _ 4 & mdash The other. 3, the gas-fired steam boiler types and capacity feed pump shall be provided with a reserve, and when the maximum feed pump stops operating, the remaining total flow rate shall be able to meet 110% of the water supply required by all operating boilers at the rated evaporation capacity; When the boiler room is equipped with a dewarming device or a heat accumulator, the total flow rate of the feed pump shall be included in its water consumption. 4. One or more boilers with the same steam pressure may choose to operate side by side with two or more feedwater pumps, if the main pipe is used for water supply, Then you can choose two pumps and one backup, then frequency conversion water supply, which not only reduces the consumption of electric energy, but also makes the water supply pressure stable, although the one-time investment is relatively large. However, by means of frequency conversion and energy saving measures, the investment cost can be recovered in 3 years and 4 years. 5. Gas-fired steam boilers use steam-driven feedwater pumps as accident backup pumps. Its flow rate should be able to meet 20% ~ 40% of the water supply required by all operating boilers at rated evaporative capacity. Only when the boiler room with the first-class electric load and the feed pump stop running will not cause the boiler to be short of water, the steam-driven feed water pump may not be installed, and the non-power boiler room of the general industrial enterprise does not have such conditions, so it must be set up. Boiler selection has a direct impact on the boiler water supply system, it should be carefully selected.
The steam generator or boiler is an integral component of a steam engine when considered as a prime mover. However it needs to be treated separately, as to some extent a variety of generator types can be combined with a variety of engine units. A boiler incorporates a firebox or furnace in order to burn the fuel and generate heat.

Basic Function of a Boiler. As the name states the function of a steam boiler is very simple i.e. generating, storing and distributing the steam. The fluid is contained in the boiler drum called shell and the thermal energy released during combustion of fuel is transferred to water and this converts water into steam at the desired temperature and pressure.

BOILER TYPES FOR STEAM APPLICATIONS This article covers the basic difference between common boiler types for high pressure steam applications in the capacity range of 5,000,000 to 100,000,000 Btu/hr (5-100 MMBTU/hr or 120 - 2400 HP). This size range would be the larger commercial, institutional and industrial applications.

EFFICIENCY AND CAPACITY OF BOILERS. Two of the most important operating factors entering into the consideration of what constitutes a satisfactory boiler are its efficiency and capacity. The relation of these factors to one another will be considered later under the selection of boilers with reference to the work they are to accomplish.
