Firetube Boilers: These boilers have a flame that passes through enclosed tubes, heating the surrounding water. Firetube boilers are generally used in commercial and small industrial applications.
Watertube Boilers: These boilers heat gases in a furnace that circulates around water-containing tubes. Unlike firetube boilers, watertube boilers can handle higher pressures, making them ideal for demanding industrial processes.
Electric and Electrode Boilers: These boilers use electricity to heat water or generate steam, offering an efficient and emission-free alternative to traditional fuel-fired systems. Electric boilers rely on heating elements, while electrode boilers pass an electric current directly through the water to produce heat. Both types are ideal for applications where space, emissions, and efficiency are important considerations. Electric boilers are well-suited for residential, commercial, and industrial uses, while electrode boilers excel in a broad range of industrial settings that demand rapid steam generation and very large turn down capabilities.
There are three main types of steam boilers: firetube, watertube, and electric. Firetube boilers are compact and efficient, with combustion gases passing through tubes to heat the water, making them ideal for commercial and small industrial applications. Watertube boilers circulate water through tubes surrounded by combustion gases, making them suitable for high-pressure applications and large steam capacities. Electric boilers use heating elements to generate steam, offering an energy-efficient and emission-free alternative for residential, commercial, and smaller industrial uses.
To improve boiler efficiency, optimize combustion by maintaining the proper air-to-fuel ratio and adding advanced control systems for real-time monitoring and adjustments. If the boiler pressure vessel is in good shape, replacing an older burner will immediately improve efficiency. Regular maintenance, such as descaling and checking for leaks, also helps keep a boiler operating efficiently. Adding a condensing or standard - Flue gas economizer can also boost your efficiency.
Many industries use steam boilers, including manufacturing, food processing, pharmaceuticals, healthcare, hospitality, education, government, chemical processing, paper mills, petroleum and utilities.
In manufacturing, boilers provide heating, cleaning, and power for machinery. In food processing, they ensure safety through sterilization and pasteurization. Pharmaceuticals use them for creating sterile environments, while healthcare facilities rely on them for heating and sterilization. In buildings, on college campuses, and in the hospitality industry, boilers supply heating and hot water.
High-pressure steam is used in many industries including chemical processing, paper mills, petroleum and utilities. In the chemical industry, boilers are used for heating, distillation and reaction heating, and in pulp and paper mills, they are used to power machinery. In the oil and gas industry, high-pressure steam boilers generate hot water and steam for drilling operations, and in the utility industry, they are used for power generation.
Boilers have advanced safety features such as pressure relief valves, flame monitoring, and low- water cutoffs for safety. Adhering to boiler safety standards and regulations and performing regular maintenance further ensure boiler safety. Proper training for operators is also crucial so they know how to operate the boiler safely and respond to emergencies. Proper boiler combustion controls and boiler safety monitoring controls also contribute to long life and safe operation.
Reimers manufactures stainless steel electric steam boilers for those applications requiring pure steam and using de-ionized water having a minimum specific resistivity of 1 megohm/cm. These units provide a stainless steel surface to all wet areas and are designed and constructed within the scope of A.S.M.E. Code. This limits the design pressure to 100 psig and maximum pressure vessel size to 5 cubic feet. We offer various models from .15 to 12 B.H.P.
With competitive price and timely delivery, Partedon Group sincerely hope to be your supplier and partner.
If distilled water must be used, it will be necessary to add a "pinch" of salt once each week to the water. This will permit electricity to pass through the water for the probe controls. We suggest that "soft" treated water be used in lieu of distilled water and that the boilers be given a daily blowdown. This will prove less expensive and will work well even in hard water areas.
Yes, three options are available. 1. MFG- BY REIMERS, Underwriters' Laboratories (U.L.) allows us to "label" the boiler with your name if we include: "Mfg. by Reimers Electra Steam Inc., Clear Brook, VA. on the bottom of the label. There is no charge for this service. Our standard computer generated label can be used or you can provide your own.
2. MULTIPLE LISTING; Our name can be eliminated completely from the exterior of the boiler if a U.L. multiple listing is obtained by your company. U.L. has an initial charge for this service and an annual fee. Reimers adds no extra charges.
3. SPECIFIC DESIGN: Due to our CAD capabilities and resources of manufacturing equipment, it is feasible to design & produce equipment to your specific requirements. The UL and ASME labeling can be addressed .
Steam cleaning produces considerably less water and chemical runoff than pressure washers. It also allows the operator to "dry" the part with saturated steam after cleaning. This speeds up the process and improves productivity. For heavy steam cleaning in a production environment, we recommend our model RBH30Z- with syphon steam gun. This combination provides the versatility of using steam and/or detergent in mixture. If it is feasible, we suggest a stationary unit with appropriate steam lines to various locations with steam cleaning outlets. This eliminates moving a heavy unit (500 lbs. or more), trailing water hose and heavy electrical cable. This unit is a dry-type steam cleaner, which ejects raw steam at 80 to 90 psig. The only wetness you will get is the detergent which is syphoned into the end of the steam gun and mixes with the steam in the gun. The amount of detergent is controlled by the operator with an adjustable syphon valve on the steam gun.
Purpose:
The blowdown tank is designed to prevent high pressure steam and water from entering into drains and possibly scalding someone. Therefore, it is provided with a chamber that will allow the blowdown water to cool before discharging and allow the steam flashed from the blowdown water to vent to the atmosphere.
&#;Design:
Our blow down tank accomplishes this by:
&#; Cooling: The bottom half of the tank is full of cool room temperature water at all times. When the boiler blowdown valve is opened, the hot water from the boiler displaces (moves) this cool water out the overflow to drains. The hot water will then cool to room temperature after sitting for several hours
&#; Pressure: A large vent to atmosphere is provided on the top of the blowdown tank to allow the steam flashed from the blowdown water to vent to atmosphere. It is important that this vent be piped so that the steam will not discharge on any person.
&#;Installation:
&#; Mounting: Mount on the skid provided so that the blowdown tank is portable.
&#; Drain: Pipe this to floor drains (or to a bucket).
&#; Fill: Put water into the tank up to the drain fitting (approximately 4 gallons/ 15 liters).
&#; Vent: Thread a pipe up from the fitting to a safe discharge area.
&#; Blowdown inlet: Connect the flexible stainless steel braided hose from the boiler blowdown to this.
Our boilers require very little maintenance if blowndown daily. We do suggest that the boiler be examined after the first 90 days for small leaks (around gauge glass, valves, etc.), internally for calcium buildup (to evaluate if more or less blowdowns are required), clean probes, and generally look for problems. It is a good habit to have a technician replace the gauge glass every year, check for leaks, internally examine boiler, clean probes, etc.
Calcium is the biggest nemesis. Water of less than 1 grains hardness is preferred. For carbon steel boilers, do not use de-ionized water. Specific resistivity should be less than 25,000 ohms/cm. For stainless steel boilers, you must use de-ionized water of at least 1 megohm/cm specific resistivity.
We do not suggest that all or any replacement parts will be required for the first one to two years service. With proper maintenance, replacement parts are seldom required within this period. In some cases, specific items (i.e. elements) may need more frequent replacement. This is a factor of water treatment, maintenance, etc. The type and quantity of spare parts kept on site will vary with the application. Some high priority (surgical rooms & primary process boilers) will necessitate a replacement stock of heating elements, gaskets, fuses, and selected controls. However, Reimers does maintain a consistent stock level of parts ready for immediate shipment. Contact our factory Monday through Friday prior to 2:00 PM EST we will rush your part out the same day.
The cost of gas is generally much less expensive than electricity. However maintenance and installation costs for a gas boiler will offset the energy costs. This is because electric boilers can normally be located in the immediate vicinity where steam is required, saving considerable line loss. Also electric boilers do not use a flue/exhaust.
It is imperative that your steam piping be safely and properly installed. Poor piping will result in wet steam and poor efficiency. Some tips:
&#; Pitch steam and condensate pipes away from boiler a minimum of 2"/10 ft.
&#; Insulate piping with minimum of 2" high temp. insulation
&#; Size for loss of I BHP per 50 ft. pipe length.
&#; Maximum closed system = 25 ft. length.
Electric consumption:
(KW rating) x (#hours of operation) x (KW/HR charge) = cost per month.Normally, the customer will utilize 60% or less of this amount.&#;&#;
&#;Electric demand:
In the U.S.A., the electric utility company may also charge a "demand charge" each month equivalent to the peak amount of electricity used during a given span of minutes at anytime during the month. This is a government rule to make power providers have feed lines and reserve power that is capable of serving customer demands:(KW rating) x (demand charge) = demand cost per month
&#;Water feed costs:&#;
Blowdowns are important. Water used in these boilers should still be managed to minimize negative effects introduced by the water. We do suggest "softened" water if the normal water is very hard. This allows the blowdown to work better and reduces hard calcium buildup within the pressure vessel. Distilled water should not be used because of its expense. To calculate water usage:(B.H.P.) x (4.2 gallons per hour) x ( hours of operation) = water used(B.H.P.) X (l5.9 liters per hour) X ( hours of operation) = water usedThis formula calculates the maximum amount of water that the boiler can use. Normally, no more than 60X of this volume is used.
