SZL Coal Fired Steam Boiler Price

 The equipment is the product of coal fired steam boiler with vertical chain grate of double boiler barrel. Stable performance; The boiler body is composed of longitudinally placed upper and lower boiler barrel and convection tube bundles. The left and right sides of the boiler combustor are equipped with water wall pipes. There is a soda-water separating device and a surface blowdown device system in the upper pot, and a periodic blowdown device system in the lower pot. Economizer is arranged at the rear of the boiler. The combustion system adopts light chain grate to realize mechanical coal feeding, mechanical slag removal, and equipped with blower and induced draft fan for mechanical ventilation. 



After the fuel falls on the grate from the coal sill and enters the furnace chamber for combustion, the flue gas enters the first bundle to the front smoke box through the refraction of the rear arch combustion chamber, and then refolds into the second bundle to the back smoke box. Under the action of the induced draft fan, it enters the economizer and dust collector through the gas outlet, and then the flue gas is discharged to the atmosphere from the chimney.

SZL Coal Fired Steam Boiler Feature

1. High thermal efficiency

The combustion efficiency is more than 98%, which reduces the heat loss of mechanical incomplete combustion, and the coal fired boiler thermal efficiency can reach more than 90%.

2. Obvious environmental protection effect

(1) The use of fractional air swirl low ammonia burner, reasonable control of combustion temperature and oxygen content, effectively reduce NOx emissions.

(2) adopt advanced flue gas desulfurization method, SO2 emission concentration is low.

The tail adopts advanced bag filter, low concentration of smoke (powder) dust emission.

The use of closed feeding system and dust removal system, reduce dust pollution.

3. High security

The guarantee condition of high efficiency pulverized coal boiler system to avoid safety hidden danger is scientific and perfect technical system and advanced prevention means: adopt high reliable program ignition controller to prevent ignition and deflection in the furnace and complete extinguishing interlock protection; Electrostatic grounding, CO2 protection and other measures are adopted to prevent spontaneous combustion and explosion of pulverized coal in the tower.

4. Easy manipulation

High level of boiler system integration. And equipped with automatic intelligent monitoring system, boiler operation to achieve automatic control and regulation, continuous automatic parameter acquisition, fault alarm and safety interlock protection.

5. Compact boiler structure, reduce the height of boiler room. Do not need coal yard and ash field, less area.

Pulverized coal industrial boilers have the following advantages over traditional coal-fired boilers

(1) Centralized supply of pulverized coal: centralized mill unified supply of pulverized coal, pulverized coal quality stable;

(2) Friendly working environment: the whole system is closed operation, automatic pneumatic conveying for coal and centralized ash discharging, no dust running;

(3) Significant energy saving: full combustion of pulverized coal, high combustion efficiency, high boiler thermal efficiency:

(4) Clean emissions: low temperature combustion environment can achieve desulphurization in the furnace: burner with a low nitrogen burner, uniform temperature field, low NOx content produced during the combustion process; The tail of the bag filter, smoke (powder) dust emission concentration is low. The fly ash is discharged through the closed system without secondary pollution.

(5) Simple boiler operation: the system can be realized to start and stop, cut off the point fire source into normal operation: cut off the coal supply can be realized to stop the furnace: the system automatically monitor and adjust the operating parameters, so that the system in the best operating state;

Cost-effective: low operating costs, can recover equipment investment in a relatively short period of time;

Economize the land: boiler room cancelled the traditional coal yard and slag yard, cover an area of less.



Industrial boiler sales complete machines, automatic water treatment, high efficiency dust collector and electric control cabinet, fan and induced draft fan, slag machine, coal, machine speed regulation, economizer, decontamination device, for water pump, cylinder and conventional instrumentation equipment such as boiler using matching requirements meet the market customers, Zozen Boilers sincerely welcome you to the company business negotiations.

Parameters and technical requirements of 6-ton gas-fired steam boiler for hospital use

 The 6ton gas-fired steam boiler is commonly used in hospitals, and its process requirements are as follows: Natural gas boiler: natural gas → burner → boiler → steam → sub-cylinder → steam point. Tap water constant pressure water supply → water softener → soft water insulation water tank → energy saver → boiler. Hospitals are densely populated places, so the requirements for boiler equipment and suppliers are relatively strict. Suppliers of 6ton gas boilers must have a Class A boiler manufacturing license, a pressure vessel manufacturing license, a Class 2 boiler installation, renovation and maintenance license or above. The equipment supplier shall be responsible for obtaining relevant certificates and fees such as the registration certificate for installation and use of boiler equipment. The water supply of this series of gas boilers is designed with a flue gas condensation recovery device to recover the heat energy of the flue gas, and the exhaust gas temperature is less than...

SZS Gas-Fired Horizontal Water-Tube Saturated Steam Boiler

 The pipelines within the scope of the SZS watertube steam boiler only include the valves and pipelines from the flange of the return water check valve to the outlet valve and drain valve of the boiler body. Accessories include valves and gauges for the boiler body. Such as pressure gauges, air valves, spring safety valves, outlet and return valves, check valves, thermometers, etc. The SZS gas-fired steam boiler is equipped with a flue gas condenser at the tail of the boiler body, which reduces the flue gas temperature (<70°C), improves the boiler efficiency and reduces the harmful components in the flue gas. The boiler adopts micro-positive pressure combustion, and the furnace wall tube is a full-membrane wall structure. This series of boiler products has a certain pressure bearing capacity, and no smoke leakage and air leakage will occur when running under a slightly positive pressure state. The boiler is a self-contained boiler, which can shorten the installation period whi...

35 Tons SZS Gas Steam Boiler

 The SZS gas fired steam boiler is equipped with a flue gas condenser at the tail of the boiler body, which reduces the temperature of the flue gas, improves the efficiency of the boiler, and reduces the harmful components in the flue gas. The szs gas boiler adopts micro-positive pressure combustion, and the furnace wall tube is a full-membrane wall structure. The 35ton gas-fired boiler has a certain pressure-bearing capacity, and there will be no smoke leakage and air leakage when running under a slightly positive pressure state. The boiler is a self-contained boiler, which can shorten the installation period while meeting the transportation size requirements. At the same time, the aluminum casing and the skeleton are transported and connected by bolts, which are convenient for disassembly and maintenance. The furnace of this series of boiler products adopts a model water-cooled wall structure, and the whole boiler adopts an air-tight inner shield with a fully enclosed welding s...
